What eats porcelain crabs?

Porcelain crabs, small crustaceans found in coral reefs and rocky shore environments, have a few natural predators. These include larger fish species, such as snappers and groupers, as well as some larger invertebrates like octopuses. Additionally, certain seabirds may prey on them when they are exposed during low tide. Their small size and camouflaged appearance help them evade many potential threats.
