Blue Crab Underwater
Hairy Red Hermit Crab or Dark Knee Hermit Crab Dardanus lagopodes occurs in the Indo-Pacific from east coast of Africa to Japan and Tuamotu Archipelago in a depth range from 0-120 m, max. length 10cm. \n\nThe diet of the Hairy Red Hermit Crab is primarily herbivorous, as it feeds on various types of algae and detritus found in its habitat. It has been observed using its claws to scrape off algae from rocks and other surfaces. \n\nAs a hermit crab, Dardanus lagopodes constantly looks for suitable shells to upgrade into, as it grows throughout its life, a vital behavior, as the shell acts as its primary defense against predators. \n\nTriton Bay, Indonesia \n3°57'4.944 S 134°8'1.032 E at 16m depth

Swimming Crab or Harlequin Crab Lissocarcinus laevis occurs in tropical Central Pacific in a depth range from 9-82m. The size of the carapace is max. 3cm. \nHarlequin crabs are predators, that eat shrimps and other tiny planktonic organisms, as well as leftover food from their hosts. \nThe last hind legs are larger and flatter than the other ones. This is typical for crabs of the Portunidae family, the swimming crabs. With these flattened hind legs, they are capable of swimming through the water column, when the need arises. However, like most swimming crabs, Lissocarcinus laevis prefers to keep its feet firmly on the seafloor, or on its host for that matter. \nThis specimen was encountered in the Lembeh Strait, Indonesia.\n1°28'47.196 N 125°14'12.42 E at 10m depth

Small-dot Anemone Crab or Porcelain Anemone Crab Neopetrolisthes maculatus (ex. Neopetrolisthes ohshimai) occurs in the tropical Indo-Pacific in a depth range usually from 5 to 20m, max. size 7cm, average size 3cm. The non-territorial species lives as a couple or alone, protecting its eggs from nearby predators. Porcelain crabs are filter feeders and they filter water with their mouthpart appendages (known as the third maxillipeds) rather than using their antennae. \nThis specimen was encountered in a Merten's Sea Anemone Stichodactyla mertensii in the Lembeh Strait, North Sulawesi, Indonesia\n1°28'47.196 N 125°14'12.42 E at 17m depth
