The red-bellied pointed-headed turtle ( Emydura subglobosa ) belongs within the family of the snake-necked turtle (Chelidae) to the genus of the pointed-headed turtle ( Emydura ).
description
The females of the red-bellied pointed-headed turtle reach a length of up to 26 cm, males about 20 cm. The skin color varies from light gray to dark gray with an olive shimmer. The rear part of the carapace is wider and generally relatively flat, but bulges with age . The longitudinal keel on the carapace recedes with age. The edge shields (marginal shields) are clearly rounded on the sides. The plastron is yellowish and has red to pink stripes. The head of the red-bellied pointed-headed turtle has a basic olive color. At the level of the eyes , a yellow stripe runs along the entire length of the head and extends to the tip of the snout . The nostrils are above the tip of the snout. The underside, in the area of the chin, is slightly pink in color. Males have longer tails than females. In addition, the sewer is further back with them. Due to the aquatic way of life of the red-bellied pointed-headed turtles, clearly visible webs have formed between the toes in the course of evolution . The red-bellied pointed-headed turtle is a very good swimmer. The legs are strongly built and end in strong claws . They only go to the country to lay their eggs and sunbathe. The diurnal red-bellied pointed-headed turtle is not yet threatened in its species.
distribution
The natural habitat extends over tropical and subtropical rainforest areas in Australia and New Guinea . They predominantly live on slowly flowing waters such as rivers, large lakes and extensive swamps.
food
Red-bellied pointed-headed turtles are omnivores and live on insects , mollusks and aquatic plants. With their strong jaws, they can crack snail shells, for example. They also eat ripe fruit when kept .
Reproduction
The main mating season begins in September. The female lays about 5 to 20 eggs in a hollow that is carefully closed. The eggs have a length of 35 to 38 mm, a width of 19 mm and an average weight of around 8 grams. Depending on the incubation temperature , the young hatch after 45 to 60 days. The juvenile turtles have a hatching length of 30 mm and a weight of 5 grams.
