True Crabs

True brachyuran crabs have powerful chelae which they use to rip fish and even snails apart. To get pinched by one can be a memorable experience. Some swim, while others crawl, creep and sidle. It’s best to keep them in separate aquaria or they may eat your prized tank mates.

that survives well in the aquarium. It will normally bury completely out of sight in sand or light gravel but when food is placed in the aquarium it erupts dramatically to seize it. To demonstrate their striking respiratory current, place them in a shallow dish with just enough water to cover their legs and they pump a geyser of water several inches high. Size: 3-6 cm.

The famous edible crab of the seafood industry, its bad disposition is redeemed by its delicious taste. Maintained in isolation from other specimens, their elaborate feeding behavior can be observed. They meticulously open juvenile oysters by expertly turning them and prying the hinges apart. Sometimes a blue crab can be observed delicately cleaning its own carapace. Blue crabs are used by physiologists to study vision and quick muscular responses. Size 12-14 cm.

two huge grinding claws are used to crush oysters, one claw for crushing and the other claw for delicately picking out the meat. Stone crab claws are an epicurean dish; and fishermen break off the huge claws and throw the crab back to regenerate new ones. It is perhaps the only living creature that you can eat partially while the rest of the animal is running around trying to survive. Lives on rocky bottoms, constructing burrows through limestone. Size: 10-12 cm.

is as preoccupied with sex as fiddler crabs. Males sit at the edge of their burrows, continuously beckoning the females with their vastly larger claw enticing them to join them down below. On a warm day when the tide recedes, the “herd” leaves their holes and parades down to the water’s edge by the thousands to eat diatoms. They sound like rustling leaves in a fall wind, when moving through the marsh grass. While they may not replace the white mouse as a laboratory experimental animal, Uca pugilator runs a close second. They are used to study neuro-secretory hormone control of mechanisms regulating light adaptation. Removal of the eye stalks causes chromotophores to contract, and the crab lightens. Injections of extract made of eye stalks into destalked crabs causes darkening. For more information, visit this site: www.fiddlercrab.info
