Different Types of Crab

Helmet Crab

These are a burrowing species of crabs that are referred to as the “masked crab” due to the way the patterns resemble a human face on the carapace.

They live in sandy substrates and feed on infaunal invertebrates like molluscs and worms. Helmet crabs have two antennae that form a type of breathing tube, allowing oxygenated water to flow to the subtrate.
