Reimann’s snake-necked turtle description

KingdomAnimalia
PhylumChordata
ClassReptilia
OrderTestudines
FamilyChelidae
GenusChelodina (1)

Due to its preference for remote rivers, Reimann’s snake-necked turtle was only first described in 1990 (4). Its skin is a rough, greyish-brown on the upperside and slightly more yellow on the underside. Tiny, round tubercles can be seen on the upper surface of the neck creating a bumpy texture to the skin (3). The smooth carapace, or shell, is dark chestnut to hazel brown in colour with un-serrated edges, and it is rather flat in comparison to many other turtle species. The head is also smooth, wider than most turtle species and dark brown to grey in colour, and the snout is slightly upturned. Reimann’s snake-necked turtles found in western Indonesia have slightly wider heads than those found in the more eastern areas such as Papua New Guinea (2).

Average female carapace length: 20 cm (2)

Reimann’s snake-necked turtle biology

Little is known about the biology of this species in the wild. However, it is known that breeding usually occurs two to three times a year. The female will produce a clutch of 6 to 16, greyish-white, oval eggs with hard shells, measuring up to 34 millimetres long (2) (3). The eggs, which weigh four to five grams (2), are laid within a nest which is a deep hole in the substrate. In captivity the young hatch after 65 to 80 days (2). Reimann’s snake-necked turtle has a diet of insects, molluscs and crayfish (3).
