[2] Decorator crabs such as the Macropodia rostrata will use the algae covering their limbs as camouflage and an emergency food ...
Horseshoe crabs primarily live at the water's bottom but they can swim if needed. In the modern day, their distribution is limited, only found along the east coasts of North America and South Asia. Horseshoe crabs are often caught for their blood, which contains Limulus amebocyte lysate, a chemical used to detect bacterial endotoxins.

A heatwave in the Bering Sea's waters may have sped up the crabs' metabolisms, ... The scientists analyzed changes in ice cover, temperatures at the bottom of the ocean, algal blooms under the sea ...
Similarly, snow crabs likely will have an adverse effect on the native species of the Barents Sea. [6] Snow crabs are found in the ocean's shelf and upper slope, on sandy and muddy bottoms. [3] They are found at depths from 13 to 2,187 m (43 to 7,175 ft), but average is about 110 m (360 ft). [7] In Atlantic waters, most snow crabs are found at ...

Kiwa tyleri, the Hoff crab, is a species of deep-sea squat lobster in the family Kiwaidae, which lives on hydrothermal vents near Antarctica. [1] The crustacean was given its English nickname in 2010 by UK deep-sea scientists aboard the RRS James Cook, owing to resemblance between its dense covering of setae on the ventral surface of the exoskeleton and the hairy chest of the actor David ...
This crabs are found in the Indian Ocean and on the west coasts of Western Australia.They can live in shallow waters, and down in deepwater a few hundred meters deeply. They especially live near sea sponges, at the bottom of rocky shores for protection and camouflage.
