Arthropods

Crustaceans reproduce sexually. They are oviparous and undergo metamorphosis, which is the process crustaceans pass through from larvae to their adult form.

Crustaceans have two pairs of antennae. They also have ten jointed legs.

The body of a crustacean is divided into 3 parts: head, thorax and abdomen. In some crustaceans, like crabs, the head and thorax may be fused together to form a cephalothorax. They have bilateral symmetry

All crustaceans have a hard exoskeleton, which protects their flesh and organs, and from predators
