8. TURTLES IN CYPRUS 8.1. Family: Bataguridae (formerly Emydidae) Mauremys
caspica (GMELIN, 1774) (Caspian Turtle, Stripe-necked Turtle) Identification: Carapace length up to 25 cm, or slightly
longer; carapace ankylosed to plastron; axillar and inguinal plates present. Carapace
low-domed; vertebral and costal plates with distinct central keels in young, gradually
become indistinct in older specimens. The suture between the anals is shorter than
that of femorals. Carapace is gray to grayish-green with reddish or yellowish markings,
the plastron with large dark or black patches. The head, neck and limbs with yellowish
stripes. Habitat & Biology: Inhabits lakes, rivers, ditches, etc. Feeds on fish and other suitable aquatic animals. Hibernates under water. A
female lays 9-20 eggs in terrestrial nests. Distribution: Its range extends from NW Africa, S Europe to
Turkey, Transcaucasica, Iran, Iraq, Syria, Israel, Northern Cyprus and some Aegean
islands. In Northern Cyprus, M. c. rivulata (Valenciennes, 1833) is present being only
in Küçük Kaymakli District, Kanli Dere River (Nicosia). 8.2. Family: Cheloniidae Caretta caretta (LINNAEUS, 1758) (Loggerhead
Turtle) Identification: Marine, carapace up to around 100 cm in adults.
Two pairs of prefrontal plates on the head; 5 pairs of costal plates on the carapace;
nuchal plate in contact with the first costals. On the outer edges of the flipper-like
limbs two claws at most. Usually 3 pairs of inframarginal plates, without pores. The
dorsum is usually reddish-brown; the venter whitish to light yellow. Habitat & Biology: Feeds on fish, molluscs and
coelenterates. A female deposits around a hundred eggs to nests dug into beach sands. Nest
building is, as in C. mydas, nocturnal. The
hatchlings emerge during the night after an incubation period of approximately two months
and enter the sea. Because of the touristic, urban and industrial usage of suitable
nesting beaches, the Mediterranean populations are gravely endangered. To prevent their
extinction, they are now protected under “Mediterranean Action Plan” (MAP). Distribution: Widespread in warm and temperate oceans, also in
the Mediterranean; sometimes seen in the Sea of Marmara and the Black Sea. The nests of
the Mediterranean populations are usually built on the southern sandy shores of Anatolia
and the northeastern shores of Northern Cyprus between Kyrenia and Dipkarpaz. Chelonia mydas (LINNAEUS, 1758) (Green Turtle) Identification: One of the bigger marine turtles with a
carapace length up to 140 cm. Only one pair of prefrontals on head; nuchal plate does not
contact the first costals; 4 pairs of costals on carapace. Each of the flipper-like limbs
contain at most only one claw. Usually 4 pairs of inframarginal plates. The dorsum is
grayish-brown, usually with yellowish or brownish markings. The venter is light yellow to
white. Habitat & Biology: The adult usually feeds on turtle grass
and other seaweed, the young is carnivorous. A female deposits around 200 eggs to its nest
dug in the beach, usually laying more than one batch (in one breeding season, up to 5
batches with a total 468 eggs have been observed). For a long time the species had an
economical importance because of its edible meat and fat, so its populations dangerously
decreased. The usage of its nesting sites with various aims further endangered the
survival of the species in the Mediterranean basin, so now, like the loggerhead, the green
turtle is also protected under MAP. Distribution: Warm oceans, also present in the Mediterranean,
rarely seen in Black Sea. Nesting sites in Turkey and Northern Cyprus exclusively in the
eastern Mediterranean coasts. In Northern Cyprus, they especially nest in the sandy shores
of Yayla (=Kum Köy) (Güzelyurt, Nicosia), Acapulco Vilage (Kyrenia) and Yeni Erenköy
(Karpaz Region). [Site Main Page] [Site Ana Sayfa] [English Herpetofauna Main Page] [Türkçe Herpetofauna Ana Sayfa] |
