Chaceon quinquedens, commonly known as the red deep-sea crab, [2] but sold as Atlantic deep sea red crab, or simply Atlantic red crab or red crab, is a crab that lives in the Atlantic Ocean off the East Coast of the United States and Canada, from North Carolina to Nova Scotia, [3] [4] and in the Gulf of Mexico.
During their larval stage, millions of red crab larvae are eaten by fish and large filter-feeders such as manta rays and whale sharks which visit Christmas Island during the red crab breeding season. Coconut crabs (alternatively known as robber crabs) have also been filmed on Christmas Island preying on red crabs. [14]
Many terrestrial crustaceans (such as the Christmas Island red crab) mate seasonally and return to the sea to release the eggs. Others, such as woodlice, lay their eggs on land, albeit in damp conditions. In most decapods, the females retain the eggs until they hatch into free-swimming larvae. [22]
Little is known about the red crab as they are usually found from 700 feet to over a mile down the canyons, off the Southeast side of Georges Bank and mid-Atlantic bight. ... The larval red crabs ...
Minuca minax, commonly known as the redâjointed fiddler crab or brackish-water fiddler crab, [1] is a species of fiddler crab that is found in the United States from Massachusetts to the Gulf of Mexico. It is one of the most common macroinvertebrates in salt marshes in these states. [2]
Pelagic red crab (Grimothea planipes)Grimothea planipes usually feeds on protists and zooplankton, but will feed by filtering blooms of diatoms. [7]As the most abundant species of micronekton in the California Current, Grimothea planipes fills an important ecological niche converting primary production into energy that larger organisms can use. [8]
The crab's round, flat carapace is slightly longer than 8 centimetres (3.1 in). Young G. grapsus are black or dark brown in colour and are camouflaged well on the black lava coasts of volcanic islands. Adults are quite variable in colour; some are muted brownish-red, some mottled or spotted brown, pink, or yellow.
A phyllosoma larva of the spiny lobster Palinurus elephas, from Ernst Haeckel's Kunstformen der Natur. The larvae of the Achelata (slipper lobsters, spiny lobsters and furry lobsters) are unlike any other crustacean larvae. The larvae are known as phyllosoma, after the genus Phyllosoma erected by William Elford Leach in 1817. They are flattened ...
