The crab porcelain is a small crab of the Porcellanidae family. With a maximum length of three inches across the leg span. The carapace length is one inch on average. Their compressed body acts as an advantage for staying stable against turbulent waters.

On the other, the body parts have many uniform small, reddish-purple spots.

The porcelain anemone crab inhabits the oceans, seas. They are endemic to the Indo-Pacific. They are primarily native to coral reefs and rocky habitats with tropical and temperate shores.
Anemone crabs are prevalent under rocks and are regularly seen on rocky beaches and shores. When an invader finds it beneath a rock, the anemone crab will run away, shocked.

Porcelain crabs live as pairs on sea anemones, displaying territorial behavior with their species.
The crab porcelain can live from three to five years under favorable conditions in rocks and coral reefs of water bodies and aquariums.
Generally, these animals are found as heterosexual pairs. They retain internal implantation, where the male passes sperm to the female as tiny packets caked spermatophore. The female imports eggs in the brood flap over the abdomen. The female can contain 1600 eggs at a time. The eggs are reddish-brown and feed on plankton. After transforming into larvae, the eggs remain in a planktonic state for many weeks before they conclude. The larva goes through one megalopa stage and two zoeal stages.
The conservation status of this porcelain anemone crab is not listed in the red list of the International Union for Conservation of Nature.

The male and female porcelain crab are called male porcelain crab and female porcelain crab.
The baby porcelain crab is called young or juvenile. The larvae resemble plankton.
They feed mainly on plankton algae. They separate their food from water with their fan-like mouthparts. They also have the mucus from anemone as food. Porcelain crabs take support of their claws for feeding and hunting for food. Their diet also includes zooplankton, brine shrimp, bloodworms, marine snowflakes, spirulina, sponges, and everything that comes their way, which they filter through the help of their fans.

Porcelain crabs spend most of their time on the adhesive and carpet anemones. Therefore, these crabs are in a commensal relationship with the anemones. Therefore, these crabs get protection, and anemones are also not disrupted by these crabs.
Neopetrolisthes maculatus of western Australia, which live in the tropical reefs, is constantly staying on or around giant sea anemones. The stinging tentacles of these anemones guard them against predators.
