Sometimes kept as scavengers in salt water aquaria. The yellowline arrow crab eats many of the smaller particles that might be found in an aquarium. Territorial behavior usually prevents more than one crab from flourishing in a tank. They work well with other species, but not usually with their own.

Morphology ( Anglèis )

fornì da Animal Diversity Web

The yellowline arrow crab, on average, is 3 to 6 centimeters in length.

What makes the yellowline arrow crabs unusual is their long, spider-like legs, and and extremely pointed head. The eight legs are extremely long, more than three times the length of their body, and resemble the legs of a daddy long-legs spider. The entire body of the yellowline arrow crab is a medium golden brown in color. Along the dorsal side of the crab's body are stripes that are white, brown, or gold depending on the individual crab. The tips of their legs are a deep violet in color. As crabs grow, they occasionally shed their exoskeleton. The new skin hardens with calcium carbonate, obtained from sea water and by ingesting the old shell (Humann 1992, and Snyderman and Wiseman 1996).

Reproduction ( Anglèis )

fornì da Animal Diversity Web

During mating, a male yellowline arrow crab holds the female against his belly to deposit a sperm packet into the female crab. A female yellowline arrow crab then carries her eggs under her abdomen until they are ready to hatch. The young crabs that emerge are called zoea. They are called zoea only during the larval stage of growth. During this time the zoea are transparent, have a rounded body, and swim towards the surface of the sea They live in open water, feeding on small plankton. The zoea grows and molts the old skin by replacing it with the new skin. Eventually the larval crab emerges from the molt in a new stage, called a megalops. During this stage of growth the body and limbs finally start to look more crab-like in form, though the abdomen has still not folded up. The yellowline arrow crab will continue to shed, replacing their exoskeleton, and will eventually grow to look like any other adult yellowline arrow crab. The reproduction cycle can then begin again (Olhausen and Russo 1981, and Anonymous 2000).

Stenorhynchus seticornis ( Anglèis )

fornì da wikipedia EN

Stenorhynchus seticornis, the yellowline arrow crab or simply arrow crab, is a species of marine crab.

Description

S. seticornis off Tenerife

The body of S. seticornis is triangular, and the rostrum is drawn out into a long point with serrate edges.[1] The legs are also long and thin, up to 10 cm (3.9 in) across,[2] and the animal's carapace may be up to 6 cm (2.4 in) long.[3] Colouration is variable in this species; the body may be golden, yellow or cream, marked with brown, black or iridescent-blue lines; the legs are reddish or yellow, and the claws are blue or violet.[3] This species presents as diagnostic features: triangular body with long pointed snout (rostrum), carapace decorated with fine dark lines and claws often have violet tips. S. seticornis is most commonly associated with anemones, in groups ranging from one to six individuals in south-eastern Brazil.[4]

Distribution

Stenorhynchus seticornis is commonly found in the shallow sub-tidal on rock bottoms, corals, calcareous algae, and also on soft sediments, such as shelly gravel and sand. Its geographical distribution is restricted to the Occidental Atlantic, from North Carolina to Argentina.[5] Stenorhynchus seticornis is found in the western Atlantic Ocean, from North Carolina and Bermuda to Brazil, including throughout the Caribbean Sea,.[3] It lives on coral reefs at depths of 10–30 feet (3.0–9.1 m).[6]

Ecology and behaviour

S. seticornis is nocturnal and territorial.[7] It eats small feather duster worms and other coral reef invertebrates.[7] This crab is commonly kept in reef aquariums to control bristle worm populations.[8]

S. seticornis is one of a number of different invertebrates that are found living in association with the sea anemone, Lebrunia danae. It is often found among the anemone's pseudotentacles along with Pederson's cleaning shrimp (Ancylomenes pedersoni) and the spotted cleaner shrimp (Periclimenes yucatanicus).[9]

S. seticornis have displayed notable negative phototaxis, meaning the organism prefers to avoid sunlight.[10] This species changes location during the day and nighttime.[10]

S. seticornis is also notable for its propensity to decorate its body by attaching materials as camouflage, or if the attached organisms are noxious, to ward off predators through aposematism.[11][12]

Symbiotic Relationships

There is a considerable number of reports on cleaning symbiosis among reef fish, moray eels, and squirrelfish.[4] This is a somewhat unexpected relationship as moray eels and squirrelfish can be considered dangerous clients, because crabs are important elements of their diets.[4] This behavior has only been observed in the natural environment in Brazilian waters but it is believed that this behavior also exists throughout its distribution.[4]

Life cycle & Reproduction

During mating, the male places a spermatophore on the female, which she uses to fertilise her eggs. These fertilised eggs are then carried on the female's pleopods until they are ready to hatch into zoea larvae.[7] These swim towards the ocean surface and feed on plankton. They grow through a series of moults, and eventually metamorphose into the adult form.[7] When mature, the spermatozoa of S. seticornis show five lateral arms, similar to the sperm morphology of Inachus phalangium.[13]

Breeding Period

Climate majorly regulates the breeding period of the arrow crab. Seasonal variation of water temperature and sunlight duration are considered as the most important variables determining the breeding period of arrow crabs.[14]

There is a positive relationship between fecundity and the size of the parental female.[5] In fact, the size of the female is the key variable in determining the number of eggs per batch. The female also determines the reproductive output of arrow crabs.[15]

Larval Stage

Larvae that have grown in shallow water differ from larvae that grow in deeper water. The key difference is in the setation of the endopodite of the maxilla.[16]

Taxonomic history

Stenorhynchus seticornis was first described by Johann Friedrich Wilhelm Herbst in 1788, under the name Cancer seticornis. It was also described as "Cancer sagittarius" by Johan Christian Fabricius in 1793, a name which is now a junior synonym of S. seticornis.[17] Pierre André Latreille erected the genus Stenorhynchus (originally mis-spelt Stenorynchus) in 1818,[17] and S. seticornis was confirmed as the type species by the International Commission on Zoological Nomenclature in 1966.[18]

Stenorhynchus seticornis ( Spagneul; Castilian )

fornì da wikipedia ES

Stenorhynchus seticornis es una especie de crustáceo decápodo de la familia Inachidae. Su nombre común es cangrejo flecha de línea amarilla o cangrejo araña. Recibe su nombre gracias a sus patas largas y delgadas, parecidas a las de una araña.

Morfología

Tiene un característico largo rostro espinoso y unas largas, y muy finas, patas. El apéndice nasal lo utiliza como arpón para atrapar presas.[3]​ El caparazón y las patas son de color marrón rojizo, y las pinzas de un gris violáceo. Sus articulaciones son de color rojo vivo, con líneas marrones o negras. Sus antenas sensoriales son mucho más pequeñas que las de las langostas o gambas. Todo su cuerpo está recubierto de un exoesqueleto o cutícula fuertemente calcificado, que le brinda protección. Su sistema nervioso es muy compacto y centralizado, si lo comparamos con la mayoría de artrópodos. Los órganos reproductores están, en ambos sexos, en la parte ventral del caparazón. La especie tiene quelíceros que utiliza para atrapar presas, provocar a los rivales y atraer pareja.

Es una especie muy pequeña, su caparazón raramente supera 1 cm de tamaño,[4]​ y el tamaño total del cuerpo alcanza unos 6 cm.[3]

Alimentación

Se alimenta de pequeños crustáceos y otros invertebrados como gusanos poliquetos.

Reproducción

Como en la mayoría de braquiuros, la luz y la temperatura son los principales factores medioambientales que determinan la actividad reproductiva, no obstante, en su caso no está sujeto a periodos determinados y se produce en cualquier época del año. El ciclo de vida comienza con una fase larval planctónica. Según madura la larva, tiene una serie de mudas que le permiten crecer y finalizar el proceso de maduración.

Hábitat y distribución

Habita en arrecifes y sobre rocas. Camuflados en especies de anémonas, corales duros y blandos, o esponjas. Su rango de profundidad es de 9 a 180 m, y el rango de temperatura entre 18.85 y 27.70 ºC.[5]

Se distribuye en el océano Atlántico occidental, desde Carolina del Norte hasta Argentina, siendo común en Florida y el Caribe.

Crabe flèche ( Fransèis )

fornì da wikipedia FR

Stenorhynchus seticornis

Le crabe flèche (Stenorhynchus seticornis) est une espèce de crustacés décapodes de la famille des Inachidae.

Distribution

Ce crabe se rencontre sur les côtes tropicales de l'océan Indien, de l'océan Pacifique et de l'océan Atlantique occidental.

Description

Les pinces

Le crabe flèche peut facilement fouiller dans les trous entre les coraux grâce à ses longues pinces. Les poissons qui s'y réfugient ont tort d'aller dans les cachettes à cause de cela.

Le museau

Si un petit poisson passe à proximité du crabe flèche alors celui-ci l'empale. Le poisson se débat pour fuir, en vain. Il reste embroché et le crabe attend qu'il meure pour le manger.

Autotomie

Si un crabe flèche perd une patte, quand il mue, un morceau de patte réapparaît. Au bout de sept mues, la patte perdue est reconstituée.

Pour les humains

Si un être humain passe à proximité d'un crabe flèche alors celui-ci le pique. C'est son moyen de défense contre un agresseur qui passe tout près.

Stenorhynchus seticornis ( portughèis )

fornì da wikipedia PT

Stenorhynchus seticornis, também conhecido como Caranguejo-aranha, Caranguejo-seta ou Caranguejo-de-linhas-amarelas, é uma espécie de caranguejo marinho encontrada no Atlântico Ocidental, da Carolina do Norte (Estados Unidos) até a Argentina.

Descrição

 src=
Stenorhynchus seticornis

O corpo do Stenorhynchus seticornis é triangular, e o rostro é alongado em uma ponta com bordas serrilhadas.[1] As pernas também são longas e finas, até 10 cm (3.9 in) transversalmente,[2] e a carapaça do animal pode ter até 6 cm (2.4 in) muito tempo.[3] A coloração é variável nesta espécie; o corpo pode ser dourado, amarelo ou creme, marcado com linhas marrons, pretas ou iridescentes-azuis; as pernas são avermelhadas ou amarelas e as garras são azuis ou violetas.[3] Esta espécie apresenta-se como características diagnósticas: corpo triangular com focinho longo e pontiagudo (rostro), carapaça decorada com finas linhas escuras e garras frequentemente com pontas violetas. S. seticornis é mais comumente associado a anêmonas, em grupos que variam de um a seis indivíduos no sudeste do Brasil.[4]

Distribuição

Stenorhynchus seticornis é comumente encontrado em submarés rasas em fundos de rocha, corais, algas calcárias e também em sedimentos moles, como cascalho e areia. Sua distribuição geográfica restringe-se ao Atlântico Ocidental, da Carolina do Norte à Argentina.[5] Stenorhynchus seticornis é encontrado no oeste do Oceano Atlântico, da Carolina do Norte e Bermudas ao Brasil, incluindo em todo o Mar do Caribe.[3] Vive em recifes de coral a profundidades de 3 a 9 10–30 ft (3.0–9.1 m).[6]

Ecologia e comportamento

Stenorhynchus seticornis é noturno e territorial.[7] Ele come pequenos vermes espanadores e outros invertebrados de recife de coral.[7] Este caranguejo é comumente mantido em aquários de recife para controlar as populações de vermes de cerdas.[8]

S. seticornis é um dos vários invertebrados encontrados vivendo em associação com a anêmona do mar, Lebrunia danae. É frequentemente encontrado entre os pseudotentáculos da anêmona junto com o camarão limpador de Pederson (Ancylomenes pedersoni) e o camarão limpador manchado (Periclimenes yucatanicus).[9]

S. seticornis exibiu notável fototaxia negativa, o que significa que o organismo prefere evitar a luz solar.[10] Esta espécie muda de localização durante o dia e a noite.[10]

Relações simbióticas

Há um número considerável de relatos sobre a simbiose de limpeza entre peixes de recife, moreias e esquilos.[4] Esta é uma relação um tanto inesperada, visto que moreias e esquilos podem ser considerados clientes perigosos, porque os caranguejos são elementos importantes de suas dietas.[4] Esse comportamento só foi observado no ambiente natural das águas brasileiras, mas acredita-se que esse comportamento também exista em toda a sua distribuição.[4]

Reprodução e ciclo de vida

Durante o acasalamento, o macho coloca um espermatóforo na fêmea, que ela usa para fertilizar seus óvulos. Esses ovos fertilizados são carregados nos pleópodes da fêmea até que estejam prontos para se transformar em larvas de zoea.[7] Estes nadam em direção à superfície do oceano e se alimentam de plâncton. Eles crescem por meio de uma série de mudas e, eventualmente, metamorfoseiam na forma adulta.[7] Quando maduros, os espermatozóides de S. seticornis apresentam cinco braços laterais, semelhantes à morfologia dos espermatozoides de Inachus phalangium.[11]

Período de reprodução

O clima regula principalmente o período de reprodução do caranguejo-seta. A variação sazonal da temperatura da água e da duração da luz solar são consideradas as variáveis mais importantes na determinação do período de reprodução dos caranguejos-seta.[12]

Existe uma relação positiva entre a fecundidade e o tamanho da fêmea parental.[5] Na verdade, o tamanho da fêmea é a variável chave na determinação do número de ovos por lote. A fêmea também determina a produção reprodutiva dos caranguejos-flecha.[13]

Estágio de larva

As larvas que cresceram em águas rasas diferem das larvas que crescem em águas mais profundas. A principal diferença está na configuração do endopodite da maxila.[14]

História taxonômica

Stenorhynchus seticornis foi descrito pela primeira vez por Johann Friedrich Wilhelm Herbst em 1788, sob o nome de Cancer seticornis. Também foi descrito como "Cancer sagittarius" por Johan Christian Fabricius em 1793, um nome que agora é um sinônimo júnior de S. seticornis.[15] Pierre André Latreille erigiu o gênero Stenorhynchus (originalmente escrito incorretamente Stenorynchus) em 1818,[15] e S. seticornis foi confirmado como a espécie-tipo pela Comissão Internacional de Nomenclatura Zoológica em 1966.[16]
