The Red Reef Hermit Crab (Dardanus arrosor) is a decapod crustacean in the Diogenidae family of crabs. It is also known as the Mediterranean Hermit Crab.
The Red Reef Hermit Crab has a beige-coloured shell, called a carapace. The body of the Hermit Crab is hidden in the shell. The colour of its body varies from bright red to bright orange. Its eyes are at the tips of two eyestalks. The eyestalks are streaked red and white, and the eyes are bluish. It is a decapod, which means that it has ten appendages (two claws and eight legs). Its two red claws have a black or yellow tip. The claws have hair-like spines and warty tubercules. The left claw is larger than the right claw.

The Geoffroy’s Side-Necked Turtle (Phrynops geoffroanus) is a freshwater aquatic reptile in the Chelidae family of long-necked turtles. It is a chelonian or a chelid. Chelonians include turtles, tortoises, and terrapins. It is also known as the Geoffroy’s Toadhead Turtle.
The Geoffroy’s Side-Necked Turtle is black to dark-grey. Its carapace (top shell) is slightly domed. Its tail and legs are grey-brown, and its plastron underbelly (bottom shell) is yellowish. Instead of its neck sticking in and out, it has a side-necked position where it places its head sideways in its shell. It has four sharp claws on its feet.
The Geoffroy’s Side-Necked Turtle does not have a hinged plastron, so it has to put its head sideways under its shell. But this means that it has a strong neck. When it is upside down, it can flick its muscular neck to right itself – to turn itself the right way up. Other terrapins and tortoises are unable to do this.
