Porcelain crab with eggs. Porcelain crabs (family Porcellanidae) live in symbiotic relationships with different hosts such as corals and anemones. They hide within the shelter of the coral arms and in return will attack predators such as crown of thorn starfish. Female crabs carry and protect their eggs until they develop and hatch into planktonic larvae. Photographed off Komodo National Park, Komodo, Indonesia.
