Die Waldschildkröte (Chelonoidis denticulatus)[1] ist eine Art der Gattung Chelonoidis aus der Familie der Landschildkröten (Testudinidae).
Die Waldschildkröte kann 60–70 cm groß werden. Die Grundfarbe des Panzers ist dunkelbraun bis hellbraun, aber niemals schwarz wie bei der nahe verwandten Köhlerschildkröte (Chelonoidis carbonarius). Auffällig sind die gelben Schuppen an den Beinen, im englischsprachigen Raum wird sie daher als Yellow-Foot Tortoise bezeichnet. Gelbe Flecken finden sich auch als Zeichnung des Kopfes, diese gehen jedoch niemals ins Rötliche über, wie sehr oft bei der Köhlerschildkröte. Trotzdem ist die Abgrenzung zu dieser ähnlich gezeichneten Schildkröte manchmal schwierig.
Der Panzer ist hoch aufgewölbt, aber relativ schmal. Es gibt einen Geschlechtsdimorphismus, die erwachsenen Männchen sind bei dieser Art meist kleiner als die Weibchen.
Charakteristisch für die Waldschildkröten sind paarige, relativ große Schuppen an der Kopfoberseite direkt hinter der Nase, die bei Köhlerschildkröten nicht zu finden sind.
Die Waldschildkröte stammt aus Südamerika, wo sie die immerfeuchten, aber auch die wechselfeuchten tropischen Regenwälder bewohnt. Man findet sie in Kolumbien, Venezuela, den Guayanas, Brasilien, Peru, Bolivien und Paraguay, aber auch auf der Insel Trinidad.
Die Tiere sind relativ leicht zu halten, wenn man ihnen entsprechende Temperaturen und Luftfeuchtigkeit bieten kann. Sie brauchen aber wegen ihrer Größe viel Platz und wegen ihrer Lebhaftigkeit am besten ein großes Freilandgehege.
In ihrem natürlichen Lebensraum haben die Waldschildkröten ein breites Nahrungsspektrum zur Verfügung. Gräser, Blätter und tropische Früchte sind die Hauptnahrungsquelle, daneben fressen sie auch Schnecken, Würmer und Insekten.
In Gefangenschaft haben sich Löwenzahn, Endivien, Spinat, Petersilie und Zucchetti bewährt, wichtig ist eine abwechslungsreiche, kalziumreiche und phosphatarme Nahrung. Auch Früchte wie Bananen, Kiwi, Äpfel, Zitrusfrüchte und Erdbeeren werden gefressen. Im Freilandgehege fressen die Schildkröten auch lebende Schnecken und Würmer.
Die Nachzucht der gefährdeten Art ist unter geeigneten Bedingungen möglich. 28–31 °C Bebrütungstemperatur sind nötig, mindestens 85 % Luftfeuchtigkeit. Die Eier werden dabei in Vermiculite gelegt, das Substrat muss sehr feucht gehalten, jedoch Staunässe vermieden werden. Nach 120 bis 160 Tagen schlüpfen erfahrungsgemäß (nicht aus allen Eiern) die Jungtiere.
Die Waldschildkröte (Chelonoidis denticulatus) ist eine Art der Gattung Chelonoidis aus der Familie der Landschildkröten (Testudinidae).

The yellow-footed tortoise (Chelonoidis denticulatus), also known as the Brazilian giant tortoise,[2] commonly referred to as the Brazilian giant turtle, or more commonly, the big turtle, is a species of tortoise in the family Testudinidae and is closely related to the red-footed tortoise (C. carbonarius). It is found in the Amazon Basin of South America. The species name has often been misspelled as denticulata, an error introduced in the 1980s when Chelonoidis was elevated to genus and mistakenly treated as feminine, an error recognized and fixed in 2017.[3]
With an average length of 40 cm (15.75 in) and the largest known specimen at 94 cm (37 in), this is the sixth-largest tortoise species on Earth, after the Galapagos tortoise, the Aldabra tortoise, the African spurred tortoise (Geochelone sulcata, typical size 76 cm (30 in)), the leopard tortoise (Stigmochelys pardalis), and the Asian forest tortoise (Manouria emys emys, typical size 60 cm (23.6 in)).
The yellow-footed tortoise is also called the yellow-foot or yellow-legged tortoise, the Brazilian giant tortoise, or South American forest tortoise, as well as local names such as morrocoy, woyamou or wayamo, or some variation of jabuta. Many of the local names are shared with the similar red-footed tortoise.[4]
Originally, Karl Linnaeus assigned all turtles and tortoises to the genus Testudo and identified this species as Testudo denticulata in 1766 with testudo meaning turtle, and denticulata meaning "tooth-like", referring to the jagged or serrated edges of the shell. Soon the term Testudo was only being used for tortoises as opposed to all chelonians, with tortoises defined by completely terrestrial behaviors, heavy shells, and elephant-like limbs with nails but no visible toes. The species got several other names, as well, for several reasons such as difficulty in distinguishing it from the red-footed, confusion over locations, researchers thinking they had discovered a new species in collections or in the field, etc.
Leopold Fitzinger created the genus Geochelone, meaning "earth turtle" for medium-to-large tortoises that did not come from the Mediterranean area (which remained Testudo), or have other special characteristics such as the hinged shells of the genus Kinixys. Fitzinger further used the term Chelonoidis as a subgenus to categorize Geochelone from South America. Neither term was widely used until they were resurrected by researchers such as Williams in 1960.[5]
Researchers such as Roger Bour and Charles Crumly separated Geochelone into different genera based largely on their skulls. They created or re-established several genera: Aldabrachelys, Astrochelys, Cylindraspis, Indotestudo, Manouria, and Chelonoidis. The debate is on-going over the definitions and validity of some of these genera. Chelonoidis is primarily defined as being from South America, lacking a nuchal scute (the marginal scute located over the neck) and a large, undivided supracaudal (the scute or scutes directly over the tail).[6]
Chelonoidis is made up of two very different-looking groups: the C. carbonarius group with the yellow-footed and red-footed tortoises; and the C. chilensis group with the Galapagos tortoises (C. niger), Argentine tortoise (C. chilensis), and Chaco tortoise (C. petersi). The taxonomic and evolutionary relationship of these two groups is poorly understood.[7]
Yellow-footed tortoises are a large species – fifth-largest overall and third-largest mainland species, after the Aldabra giant tortoise (Aldabrachelys gigantea), Galapagos giant tortoise (Chelonoidis niger), African spurred tortoise, and Asian forest tortoise. Typical sizes average 40 cm (15.75 in), but much larger specimens are common. The largest known specimen is a female that was 94 cm (37 in) long.[8] They closely resemble the red-footed tortoise, and can sometimes be difficult to tell apart, especially as a preserved specimen, which led to quite a bit of confusion over the names and ranges.
The carapace (shell top) is a long oval with parallel sides and a high-domed back that is generally flat along the vertebrals (scutes or shell scales along the top of the carapace) with a slight peak near the hind end. There are five vertebral scutes, four pairs of costals, eleven pairs of marginals, no nuchal scute (the marginal over the neck) and a large, undivided supracaudal (the marginals over the tail). The front and rear marginals (scutes along the edge of the carapace) are slightly serrated in front and rear of young yellow-footed tortoises. The carapace is yellowish brown to dark brown or even black at the edges of the scutes. The areola in each scute are pale yellow, orange or light brown and blend into the darker carapace.
The plastron (shell bottom) is thick around the edges, and the gulars (front pair of plastron scutes) do not project past the carapace. The plastron is yellow-brown turning nearly black near the seams.
The head is relatively small and longer than wide. The upper jaw has three tooth-like points. There are large black eyes with a tympanum behind each eye. The skin of the head and limbs is black with yellow to orange scales on top and around the eye and ear. The forelimbs have five claws, are long and slightly flattened. They are covered with fine, dark scales and slightly overlapping larger scales on front in the same color as the head. The hind limbs are elephant-like with four claws, and are covered in small scales colored like the forelimbs. The tail varies in length by gender and has a row of colored scales on the sides.[9]
Adult males average slightly larger than females, but the largest specimens tend to be females. Males develop a distinctive incurving of sides, giving them a well-defined "waist", and a deeply in-curved plastron. The female has a short, conical tail, while the male has a longer, more muscular tail that is generally carried tucked along one side. The anal notch of the male is also larger, presumably to allow better tail mobility.[10]
There is some disagreement as to which habitat is the preferred type for yellow-footed tortoises. Some feel they prefer grasslands and dry forest areas, and that rain-forest habitat is most likely marginal. Others suggest humid forest is the preferred habitat. Regardless, they are found in drier forest areas, grasslands, and the savanna, or rainforest belts adjoining more open habitats. The red-footed tortoise shares some of its range with the yellow-footed tortoise. In ranges shared in Surinam, the red-footed tortoise has moved out of the forests into grasslands (created a result of slash and burn agriculture), while the yellow-footed tortoise has remained in the forest.
These tortoises make a sound like a baby cooing with a raspy voice. Tortoises also identify each other using body language. The male tortoise makes head movements toward other males, but the female does not make these head movements. Male tortoises also swing their heads back and forth in a continuous rhythm as a mating ritual. Mating occurs all year round for the yellow-footed tortoise. There is no parental care of the young and the baby tortoises will fend for themselves, starting by eating calcium-rich plant matter.
The yellow-footed tortoise eats many kinds of foliage. They are too slow to capture any fast animals. In the wild, their diets consist of grasses, fallen fruit, carrion, plants, bones, mushrooms, excrement, and slow-moving invertebrates such as snails, worms, and others they are able to capture. In captivity, they are fed oranges, apples, melons, endive, collard greens, dandelions, plantain, ribwort, clover, shredded carrots, insects, worms, cuttlebone, tortoise vitamins, edible flowers, and alfalfa pellets. Each yellow-footed tortoise in the wild reaches the age of maturity at about 8–10 years. The fecundity of a female generally depends on her size; the bigger they are, the more eggs they can produce. On average, a female will create about six to 16 eggs per year, although some female individuals may not reproduce each year. The eggs have brittle shells and are elongated to spherical, about 3–6 cm in diameter. The egg size will increase with the body size of the tortoise. The young are self-sufficient from birth. The yellow-footed tortoise can live around 50–60 years.
Breeding is synchronized with the onset of the rainy season (from July to September), where a general increase in activity is noted. Males identify each other by eliciting a characteristic head movement, a series of jerks away from and back to mid-position. Another male will make the same head movements. No head movement in response is the first indication that the other tortoise is a female. Scientific experimentation and observation has also indicated head coloration has to be correct. He will then sniff the cloacal region of the other tortoise. Copulation usually follows, though sometimes there is a period of biting at the legs. During courtship and copulation, the male makes clucking sounds very much like those of a chicken, with a set pattern in pitches of the clucking sounds. Rival males will battle, attempting to overturn each other, but neither the males nor females will defend a territory. They are considered nomadic in their movements. In almost every tortoise species where male combat occurs, the males are always larger than the females. This is in comparison to aquatic species, where the males are usually smaller than the females and do not engage in male-to-male combat. Species with male combat are thought to have evolved larger males because they have a better chance of winning a bout and mating with a female, thus passing on their larger size to their offspring. Species with smaller males evolved because smaller males are more mobile and can mate with a large number of females, thus passing on their genes.
Chelonoidis denticulatus is an endangered species. The major populations located in South America are protected under the Convention on International Trade in Endangered Species, Appendix II.
As with many species of turtles and tortoises, many yellow-footed tortoises end up as food items in local markets.
This species of tortoise is popular in the pet trade.

The yellow-footed tortoise (Chelonoidis denticulatus), also known as the Brazilian giant tortoise, commonly referred to as the Brazilian giant turtle, or more commonly, the big turtle, is a species of tortoise in the family Testudinidae and is closely related to the red-footed tortoise (C. carbonarius). It is found in the Amazon Basin of South America.

La tortuga terrestre de patas amarillas, motelo (en el Perú), morrocoy de la selva o morrocoy amazónico (Chelonoidis denticulata) es una tortuga que vive en el bosque tropical húmedo. Originaria de Suramérica, se encuentra en las selvas de Colombia, Venezuela, Guayanas, Trinidad y Tobago, Brasil, Ecuador, Perú, y Bolivia.
La tortuga de patas amarillas es mucho mayor que su vecina, la tortuga de patas rojas (Geochelone carbonaria), y es la mayor tortuga terrestre continental de toda América del Sur. Su caparazón mide de 50 a 65 cm en los machos y entre 65 cm y 75 cm en las hembras, es de color marrón oscuro (nunca negro) con círculos más claros o amarillos. El pecho es marrón con cuadros amarillos, aplanado en las hembras y cóncavo en los machos. Tiene múltiples manchas amarillas en las patas y en la cabeza, por eso es conocida como la tortuga de patas amarillas. La piel es de color negro brillante con marcas amarillas en la cabeza y en la mandíbula inferior.
Hay un cierto desacuerdo sobre qué hábitat es el preferido de las tortugas de patas amarillas. Algunos expertos consideran que su hábitat son los pastos y los bosques secos tropicales y subtropicales, y que el hábitat de la selva tropical es marginal. Otros sugieren que los bosques húmedos son su hábitat preferido. En cualquier caso se encuentran en zonas forestales secas, prados y sabanas, o en hábitats más abiertos. La tortuga de patas rojas comparte algunos hábitats con la tortuga de patas amarillas. En los rangos que se comparten en Surinam, la tortuga de patas rojas ha salido de los bosques para ir a los pastos (que son el resultado de la tala y quema para la agricultura), mientras que la tortuga de patas amarillas se ha mantenido en el de los bosques.
Las tortugas se identifican entre sí mediante el lenguaje corporal. La tortuga macho hace movimientos de la cabeza hacia otros machos, pero las hembras no hacen estos movimientos de la cabeza. Las tortugas machos también giran la cabeza hacia atrás y hacia adelante en un ritmo continuo como ritual de apareamiento. El apareamiento se produce durante todo el año en la tortuga de patas amarillas.
En su hábitat natural tiene un amplio espectro de alimento disponible. Las hierbas, hojas y frutas tropicales son su fuente principal de alimento. Además comen caracoles, gusanos e insectos. En cautividad se alimentan de naranjas, manzanas, melones, escarola, col rizada, diente de león, plátano, ribwort, trébol, zanahoria rallada, insectos, gusanos, sepia, vitaminas de tortuga, flores comestibles y alfalfa. La tortuga de patas amarillas en la naturaleza llega a la madurez a los 8-10 años. La fecundidad de una hembra en general depende de su tamaño, cuanto más grandes son más los huevos que pueden producir. En promedio, una hembra puede producir unos 6-16 huevos por año, aunque algunas hembras no se pueden reproducir cada año. Los huevos tienen una cáscara frágil y se alargan esféricamente, y son de aproximadamente 3-6 cm de diámetro. El tamaño de los huevos aumenta con el tamaño del cuerpo de la tortuga. Los jóvenes son autosuficientes desde su nacimiento. La tortuga de patas amarillas puede vivir unos 50-60 años.
Maduran sexualmente entre los 5 y 7 años de edad. El macho suele ser muy territorial frente a sus semejantes. Durante el apareamiento sigue a la hembra y la presiona con mordeduras y golpecitos, hasta conseguir que acepte el acoplamiento, tras el cual la hembra deposita 3-8 huevos, lo que pasa hasta 7 veces al año. Los huevos requieren de un período de incubación de alrededor de 4 a 5 meses, con una temperatura de 28 °C a 29 °C y con un alto grado de humedad. La reproducción está sincronizada con el inicio de la temporada de lluvias (de julio a septiembre), donde se observó un aumento general de la actividad. Los machos se identifican entre sí mediante un movimiento de la cabeza característico. Si no obtiene del otro un movimiento de la cabeza en respuesta, es la primera indicación de que la otra tortuga es una hembra. La experimentación científica y la observación también han indicado que la coloración de la cabeza debe ser la correcta. A continuación, hará olor la región cloacal de la tortuga hembra. La cópula en general sigue, aunque a veces hay un periodo de persecución. Durante el cortejo y la cópula el macho emite sonidos que suenan muy parecido al de un pollo. Los machos rivales se enfrentarán en un intento de anulación, pero ni los machos ni las hembras defienden un territorio, son considerados nómadas en sus movimientos. Los machos son más grandes que las hembras, se cree que con el combate el macho ha evolucionado más grande, porque los machos más grandes tienen una mejor oportunidad de ganar un combate y de conseguir el apareamiento con una hembra, por lo que pasa su mayor tamaño a sus descendientes. Las especies con machos más pequeños que las hembras evolucionaron en machos más pequeños porque son más móviles y pueden aparearse con un gran número de hembras, y eso se transmitió en sus genes.
Como con muchas otras especies tropicales en la Amazonia la tortuga se utiliza como ingrediente principal de diversos platos de los pueblos indígenas, y es posible encontrar su carne a la venta en mercados de ciudades amazónicas. Su estado de conservación es vulnerable. En Perú no se recomienda adquirir tortugas vivas o su carne en los mercados, ya que han sido extraídas de su hábitat natural, ya que no hay viveros para estos animales. Asimismo, está prohibido su transporte y su comercialización en el país y su salida al exterior. La tortuga de patas amarillas es una especie vulnerable. Las poblaciones principales se encuentran en América del Sur, y están protegidas por el Convenio sobre el Comercio Internacional de Especies Amenazadas, (CITES), en el Apéndice II. Al igual que con muchas especies de tortugas, muchas de ellas acaban como alimento en los mercados locales.

Chelonoidis denticulatus, la Tortue charbonnière à pattes jaunes ou Tortue denticulée, est une espèce de tortues de la famille des Testudinidae[1].
Cette espèce se rencontre en Bolivie, au Brésil, en Colombie, en Équateur, en Guyane, au Guyana, au Pérou, au Suriname, au Venezuela et sur l'île Trinité[1].
Sa taille moyenne est de 40 à 50 cm de long mais certains individus de 70 cm ont été observés. Elle est la troisième plus grande espèce de tortue terrestre du monde (hors espèces fossiles) et la deuxième plus grande d'Amérique du Sud après la tortue géante des Galapagos.
Chelonoidis denticulatus, la Tortue charbonnière à pattes jaunes ou Tortue denticulée, est une espèce de tortues de la famille des Testudinidae.
La testuggine dai piedi gialli sudamericana (Chelonoidis denticulatus (Linnaeus, 1766)) è una specie di tartaruga della famiglia Testudinidae che vive nelle foreste pluviali del Sud America.[2]
Le dimensioni del carapace sono 50-65 cm per gli esemplari maschi e 65-75 cm in quelli femmina; è di colore marrone scuro (non nero) e presenta cerchi giallo chiaro. Il piastrone è marrone con riquadri gialli, appiattito nelle femmine è invece concavo nei maschi. Sono presenti più macchie gialle sulle gambe e la testa.
Si trova nelle giungle di Colombia, Venezuela, Guyana, Brasile, Ecuador, Perù, Bolivia e Paraguay.
Nel suo habitat naturale ha un ampio spettro di cibo disponibile. Erba, foglie e frutti tropicali sono la principale fonte di cibo. Anche le chiocciole, lombrichi e insetti sono fanno parte della dieta di questa specie.
La maturità sessuale è raggiunta tra i 5 e i 7 anni. Il maschio è in genere molto territoriale nei confronti di altri esemplari. Dopo che la femmina ha deposto 3 o 8 uova, ciò si può verificare anche sette volte l'anno, le uova necessitano di un periodo di incubazione che dura circa dai 4 ai 5 mesi, ad una temperatura costante di 28 a 29 °C ed un alto grado di umidità.
Come molte altre specie esotiche in Amazzonia è utilizzata come ingrediente principale di molti piatti ed è possibile trovarne la carne nei mercati delle città.
In Perù, nessuno può acquistare tartarughe vive o carni nei mercati. È anche vietato il trasporto e la commercializzazione nel Paese e la sua riproduzione all'estero.

Jabuti-tinga (Chelonoidis denticulata) é uma das duas espécies de jaboti ou jabuti. Conhecido por seu casco brilhante, é encontrado majoritariamente na Região da Amazônia e nas ilhas ao norte da América do Sul, mas pode habitar também o centro-oeste do Continente, e em menor escala, Região Sudeste do Brasil.[2]
É considerada uma espécie vulnerável.[1]
Em Tupi, Jabuti-tinga quer dizer "O que come pouco branco". Em Inglês, é chamado de Yellow-Footed Tortoise (Tartaruga de Pés Amarelos), pois possui escamas amarelas, ou amarelo-alaranjadas, nas patas e na cabeça.[2] Seu casco possui coloração mais opaca.[2]
O jabuti-tinga é maior do que o jabuti-piranga.[2] Possui cerca de 70 centímetros, podendo chegar a ter mais e 1 metro de comprimento, contando só a carapaça, o que faz dele a maior tartaruga terrestre da América do Sul continental.[2] Chega a pesar 60 quilos.[2]
Em média, um jabuti-tinga vive 80 anos, mas pode ultrapassar os 100 anos de idade.[2]
Esses répteis são onívoros: cerca de 85% de sua dieta ideal é composta de vegetais folhosos[2], 10% à base de frutas, e os 5% restantes podem ser complementados com proteína animal[2], tais como insetos, minhocas e outros pequenos animais.
Geralmente os machos da espécie atingem a maturidade sexual entre os 6 e 8 anos, e as fêmeas, entre 12 e 15 anos.[2] Na época do acasalamento o macho monta na fêmea, encaixando o seu corpo sobre o dela. Depois de alguns meses o jabuti fêmea cava uma toca e nela deposita de 3 a 20 ovos.[2] Seus filhotes, logo no primeiro mês de vida, são muito vulneráveis aos predadores por terem um casco muito mole.
Pelo fato de terem uma coloração muito brilhante, os jabutis-tingas são capturadas para o tráfico de animais e isso fez com que ele entrasse para a lista de extinção. Atualmente, é proibido possuir um jabuti-tinga como qualquer outro animal silvestre sem a autorização do IBAMA pois muitos animais, que são capturados para o tráfico, muitas vezes, acabam morrendo no caminho, antes de chegarem nas lojas, para serem vendidos como animais de estimação. Além do tráfico de animais, o jabuti-tinga está sofrendo com o desmatamento de seu habitat: a floresta Amazônica.[carece de fontes?]
