Lamarckdromia Beagle
''Lamarckdromia beagle'' (often called fluffy crab) is a crab species in the genus ''Lamarckdromia'', discovered in 2022. Description The ''L. beagle'' usually is 4-9 centimeters wide, and its body and legs are covered with long golden colored fur. Its clawed frontal legs are slightly larger than the pereiopods, or walking legs. The rearmost pair of walking legs is smaller than the others and shifted to the side of the abdomen, having been specially adapted for holding sponges to the body. Like other sponge crabs, the crab cuts a sponge or ascidian with its chelae and trims it to shape, which it holds with its hind legs for camouflague in a manner that looks similar to human headwear. They let the sponge grow and fit the shape of the crab's body. The sea sponge produces toxins to deter aquatic predators from eating it or the crab. Distribution and habitat This crabs are found in the Indian Ocean and on the west coasts of Western Australia. They can live in shallow waters, ...

Crab
Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (abdomen) ( el, βραχύς , translit=brachys = short, / = tail), usually hidden entirely under the thorax. They live in all the world's oceans, in freshwater, and on land, are generally covered with a thick exoskeleton, and have a single pair of pincers. They first appeared during the Jurassic Period. Description Crabs are generally covered with a thick exoskeleton, composed primarily of highly mineralized chitin, and armed with a pair of chelae (claws). Crabs vary in size from the pea crab, a few millimeters wide, to the Japanese spider crab, with a leg span up to . Several other groups of crustaceans with similar appearances – such as king crabs and porcelain crabs – are not true crabs, but have evolved features similar to true crabs through a process known as carcinisation. Environment Crabs are found in all of the world's oceans, as well as in fresh w ...
