Procelain crabs superficially resemble true crabs but are related to squat lobsters. They have three rather than four pairs of walking legs.
Porcelain crabs, Neopetrolisthes maculatus
Hermit crabs have an asymmetrical soft abdomen that is concealed in a scavenged gastropod shell carried by the crab.

anemone hermit crab, Dardanus pendurculatus
Decorator crabs use material from their environment to hide from or ward off predators.

Squat lobsters hold their long tails curled under the thorax. They are related to hermit crabs and porcelain crabs.

Zebra crabs live in association with Indo-Pacific sea urchins. The last segment of each leg forms a hook to hold onto sea urchin spines.
