What is a Crab’s Life Cycle?

Crabs inhabit a variety of habitats in the world, most of which are coastal. Crabs are scavengers and feed primarily on dead or live animals, though they will also eat plant material. They can grow to be over one foot long and have a wide range in color, from nearly white to brightly red.

Male crabs tend to wander more than females, and during mating season they will leave the safety of their nests to search for a suitable female.

The young crabs undergo six molts before reaching adulthood.
