Emerita (genus) : ウィキペディア英語版 | Emerita (genus)
''Emerita'' is a small genus of decapod crustaceans, known as mole crabs, sand fleas, or sand crabs. These small animals burrow in the sand in the wash zone and use their antennae for filter feeding.〔(Sand Fleas (Mole Crabs or Sand Crabs) Prime surf fishing bait )〕〔http://www.baymoon.com/~ilga/crabs/ ''All About Mole Crabs''〕 ==Description== ''Emerita'' has a barrel-shaped body. It has a tough exoskeleton and can hold its appendages close to the body, allowing it to roll in the tidal currents and waves. It has feathery antennae, which are used to filter plankton and detritus from the swash.〔 Males are typically smaller than females, and in some species, such as ''Emerita rathbunae'', the minute males live attached to the legs of the female.〔 Females are around in carapace length, depending on the species, while males vary from a similar size to females in ''E. austroafricana'', down to carapace length in ''E. rathbunae'' and ''E. talpoida''.
