Crab Crabs are in the subphylum Crustacea. They are decapods (having eight walking legs and two grasping claws), along with lobsters, crayfish and shrimps. Crabs form an order within the decapods, called the Brachyura. Their short body is covered by a thick exoskeleton. They are an extremely successful group, found all over the world.

- Even though the horseshoe crab has a hard shell and numerous appendages with claws, it is not really a crab. Horseshoe crabs belong to the phylum, Arthropoda, along with crabs, insects, and other invertebrates with jointed legs, but their closest living relatives are spiders and scorpions.True crabs have two pairs of antennae and a pair of mandibles, or jaws; horseshoe crabs lack these structures.nit Five COAST/Horseshoe Crabs Project Oceanography Fall 2001 82 with claws. In adult males, the second pair of claws (pedipalps) has a “boxing-glove” appearance and is used to grasp females during spawning. Horseshoe crabs also have four simple eyes on the top of their carapace instead of two as with the true crab.

Blue Crab FAQ Most crabs, like stone crabs and spider crabs, walk or run across the bottom. However, crabs in the family Portunidae have specially modified back legs called swimmerettes. These paddle-shaped legs rotate at 20 to 40 revolutions per minute, allowing the crab to quickly swim through the water. One of the most well known crabs in the Portunidae family is the blue crab.

- This enables the crab to orient the shell maintain its position within the shell. When a hermit crab outgrows its current shell, it will select a new one to inhabit. Long-clawed hermit crabs live mostly in shallow water and are common in tide pools and salt marshes. Broad-clawed hermit crabs live in deeper waters.

Hermit Crab Facts and Information Hermit Crab Description. The Hermit Crab has a shell that is also their home. They crawl in it and live in it when they need to rest or they fear what is around them. They have a long body and long legs that are very soft. Their bodies are quite vulnerable and that is why they have to rely on that shell to offer them plenty of protection.

- Technically hermit crabs have 10 legs including the chelipeds. 2nd &3rd pair - walking legs used for movement. Gonopores are located at the base of the 3rd pair of legs on a female. 4th pair - stubby looking legs used to move in and out of shell. 5th pair - gill grooming appendages that end in pinchers for cleaning the gills and removing excrement from the shell. Male crabs have tufts of hair concealing openings at the base of the 5th pair of legs.

They occasionally come onto shore to mate. They are commonly used as bait and in fertilizer.orseshoe crabs are used as bait to fish for eels (mostly in the United States) and whelk.

- Common hermit crab biology. In Britain, small hermit crabs are a common feature of the shore, where they frequently adopt the shells of edible periwinkles (Littorina littorea), flat periwinkles (Littorina obtusata) and dog whelks (Nucella lapidus).n deeper water, the shells of the whelk (Buccinum) are often occupied. Occasionally, if two hermit crabs meet, one will attempt to 'steal' the other's shell by forcibly evicting the current owner. The common hermit crab is an omnivorous scavenger, and can also obtain food by filtering organic particles from the water.

- Erinaceidae is the only living family in the order Erinaceomorpha, which has recently been subsumed with Soricomorpha into the order Eulipotyphla. Eulipotyphla has been shown to be monophyletic; Soricomorpha is paraphyletic because Soricidae shared a more recent common ancestor with Erinaceidae than with other soricomorphs.
