What is the anatomy of a crab?

Crabs, like other crustaceans, have several distinct body parts. Here are the main parts of a crab:


The abdomen of a crab is a soft, flexible portion located underneath the hard carapace.

It houses the crab’s reproductive organs and plays a crucial role in swimming, with specialized swimmerets that aid in propelling the crab through the water.

Swimming legs

The swimmerets, found on the crab’s abdomen, are small, leg-like appendages that facilitate swimming.

They create rhythmic movements, propelling the crab backward through the water, and also serve as brood pouches in female crabs, where eggs are carried and protected.

Crabs have compound eyes, positioned on either side of their cephalothorax.

These complex eyes provide excellent panoramic vision and are particularly sensitive to detect movement and changes in light, helping the crab spot potential predators and prey.


Crabs have two pairs of antennae on their heads.

The longer pair, called antennules, are essential for touch and taste sensations, while the shorter antennae are responsible for detecting chemical cues and smells in their environment.

Walking legs

Crabs possess four pairs of walking legs, which are sturdy and designed for mobility on various surfaces.

These legs allow the crab to walk in a sideways motion, providing stability and agility while exploring their surroundings.


The large, powerful claws, or chelipeds, are a defining feature of crabs.

They serve various purposes, such as defense against predators, capturing and handling food, and even attracting mates during courtship displays.

In some crab species, one claw is larger and used for crushing while the other is smaller and used for cutting.
