The Common Long-necked Turtle’s shell can grow up to 25 cm with its neck sometimes as long as the body. The shell is known as a ‘carapace,’ which can vary from a light brown to a dark brown. In the lighter coloured turtles, you can clearly see the black outlines across the shell. On the lower part of the shell (plastron) yellow markings can be seen with the black outlines. Their feet and claws are very strong and are webbed for swimming and tearing apart large food items. With strong jaws, they can have quite a nasty bite so be sure not to touch or aggravate them.
