what is it?
Goneplax rhomboides is a species of crab. It is known by the common name angular crab because of its angular carapace. Although it is also called the square crab , its shell is in fact more trapezoidal than square (or rhomboidal, as its scientific name might suggest). This species is also known as the mud-runner because they are able to run away quickly when threatened.
