Biology

provided by Arkive
Cagle's map turtle is a diurnal species that spends much of the day basking on logs and rocks in the water. A predominantly aquatic species, this turtle rarely comes onto land other than to nest (8). Hatchlings have been collected from September through November, indicating that the nesting season likely occurs in late spring to early summer (2). As many as three clutches of one to six eggs may be laid by a single female each year, deposited in nest-cavities approximately 15 centimetres deep near the water (2) (8). Sex is temperature-dependent, with lower nest temperatures producing males and higher temperatures producing females (8). Female Cagle's map turtle feed almost exclusively on Asian clams, while the males predominantly consume caddisfly larvae, and occasionally other insects and small molluscs (9). This difference in diet is correlated to the difference in head-width between the sexes (6). Plant remains have also been found in specimen's stomachs, but are thought to have been ingested incidentally (2) (8).

Description

provided by Arkive
Map turtles are so named for the distinctive fine lines covering their skin and upper shell (carapace), which somewhat resemble a road or contour map, and lend an air of beauty and elegance to these species that is hard to equal (3). Like most turtles found in the green-tinted rivers it occupies, Cagle's map turtle is a distinctive greenish colour (4), and arguably one of the most attractive of all map turtles (5). The upper shell is serrated at the back, bears a steep keel of sharp spine-like projections down the centre (2), and is brightly patterned with black and yellow-green concentric lines and circles (5). The head, limbs and tail are black with numerous cream to yellow lines, and there is a cream-coloured bar on the chin and a yellow 'V'-shaped mark on the top of the head (2) (5). Female Cagle's map turtles are larger than males and also have broader heads (6).

Cagle's map turtle

provided by wikipedia EN

Cagle's map turtle (Graptemys caglei) is a species of turtle in the family Emydidae. The species is endemic to Texas, where it is native to the Guadalupe, San Antonio, and San Marcos Rivers.[4]

Etymology

The specific name, caglei, is in honor of American herpetologist Dr. Fred Ray Cagle (1915–1968).[5]

Description

Cagle's map turtle has intricate patterns on the carapace and plastron, as well as serrated edges on the posterior of the carapace, as is typical of all map turtles. It is smaller than most map turtles, and very sexually dimorphic, with males reaching only 4 in (10 cm) straight carapace length, while females can exceed 7 in (18 cm) in straight carapace length.[4]

Diet

Adult females of G. caglei feed mainly on molluscs, but males and juveniles feed mainly on aquatic insects.[1]

Reproduction

Like all turtles, G. caglei is oviparous.[6] A sexually mature female may lay up to three clutches of eggs in a year.[1] Clutch size is small, only one to six eggs.[1]

De wetenschappelijke soortaanduiding caglei is een eerbetoon aan de Amerikaanse herpetoloog Fred Ray Cagle (1915 – 1968). Cagle heeft onder andere enkele soorten uit het geslacht Graptemys vernoemd.

Uiterlijke kenmerken

De schildkleur is groen, de maximale schildlengte is ongeveer 16 centimeter. Het schild heeft een duidelijke landkaarttekening de bestaat uit dunne gele lijnen. Op het midden van het schild is een lengtekiel aanwezig waarbij de hoornplaten voorzien zijn van een stekelachtige punt. De poten en kop hebben een meer afstekende strepentekening van gele en groene strepen. Rond de kop wordt de tekening golvender en aan de bovenzijde van de kop is een V-vormige gele vlek aanwezig.[2]

provided by wikipedia SV

Graptemys caglei[2] är en sköldpaddsart som beskrevs av David Haynes och Ronald R. McKown 1942. Arten ingår i släktet sågryggar och familjen kärrsköldpaddor.[3][4] IUCN kategoriserar Graptemys caglei globalt som starkt hotad.[1] Inga underarter finns listade i Catalogue of Life.[3]

Utbredning

Arten lever i floderna Guadalupe och närliggande San Antonio i delstaten Texas i sydöstra USA.[1][3] De flesta av artens individer lever i Guadalupeflodens nedersta 120 kilometer.[1]

Levnadssätt

Graptemys caglei föredrar att leva i floder med bottnar av kalkstensberggrund, varvat med stillastående partier med bottnar av finkornig sand och där det finns partier med räfflor av grus där djupet är mindre och strömmarna snabbare. Sköldpaddorna tycker om att sola på stockar, klippor och "cypressknän".[1]

Arten är i huvudsak köttätande, ungdjuren och hannarna äter mestadels insekter, medan honornas diet består i huvudsak av mollusker.[1]

Honorna lägger mellan ett och sex ägg åt gången mellan en och tre gånger per år.[1]

Опис

Загальна довжина карапаксу досягає 16—20 см. Спостерігається статевий диморфізм: самиці більші за самців. Голова дуже маленька. Панцир дахоподібний із зубчатим гребінцем уздовж хребта. Особливо добре він виражений у молодих черепах. З віком майже повністю зникає.

Голова та кінцівки темно—зеленого кольору з жовтими або темно—жовтими вертикальними смугами на. Позаду очей є великі темні плями. Карапакс зеленого кольору з великими жовтими плямами.

Спосіб життя

Полюбляє дрібні струмки з помірним перебігом, різні водойми з глибиною до 3 м із дном, який вкрито вапняком або мулом. Полює на їжу у воді, зазвичай вранці та опівдні. Харчується рибою, земноводними, водними комахами, личинками мух.

Самиця відкладає від 5 до 16 яєць у вологий пісок на березі. Температура інкубації впливає на стать черепашат. При 27-28 °C інкубаційний період триває 55—75 днів.

Розповсюдження

Мешкає у південно—центральній частині штату Техас в басейні річок Гуаделупе й Сан-Антоніо (США).

分布[編集]

アメリカ合衆国(テキサス州南部)固有種

形態[編集]

最大甲長は20cm未満。オスよりもメスの方が大型になる。背甲は緑色で、甲板に黄色い網目状の斑紋が入る。椎甲板には棘状の盛り上がり(キール)が入り、第2、3椎甲板で最も発達するもの属内ではキールは発達しない。成長に伴い背甲の斑紋やキールは消失する。

頭部や四肢は暗緑色で、黄色や暗黄色の縦縞が入る。眼の後部にはやや大型の斑紋があり、縦縞とつながり頸部へ伸びる。チズガメ属内でも頭部は小型。

生態[編集]

主に河川に生息する。水棲傾向が強いが、倒木や岩に登り日光浴を行うことも好む。

食性は動物食傾向の強い雑食で、魚類昆虫類甲殻類、貝類を食べる。主に昆虫類を食べる。

繁殖形態は卵生。

人間との関係[編集]

開発による生息地の破壊や、水質汚染等により生息数が減少している。生息地では保護され、流通も規制されている。

ペットとして飼育されることもあり、日本にも輸入されていた。流通量は少なかった。2006年にチズガメ属がワシントン条約附属書IIIに掲載され生息地であるアメリカ合衆国からの輸出が制限されたため、流通量はさらに激減した。
