Crab is a creature that is found residing, along side beaches, in almost all the countries of the world. It is omnivorous in nature and feeds on a diet comprising of algae, mollusks, worms, other crustaceans, fungi, bacteria and detritus, etc. Here are some interesting facts about these creatures :-
1. The teeth of a crab are in its stomach. After losing its claw, a crab can grow it back.
2. Crabs are also called decapods, since they have ten (deca) legs (pods). The first pair of legs is modified into claws, biologically known as CHELAE.
3. Crabs are crustaceans i.e. unlike most of the other animals; they do not have an endoskeleton. Rather, they have an exoskeleton that acts like a shied for their body.
4. In March of 2005, a new species was found 7,000 feet below sea level. It is blind. It has hair-like cillia on its arms. It lives near volcanic vents in the sea floor. It was named the "Yeti Crab".
5. Every year, 1.5 million tons of crabs are eaten over the world by humans. The species of crab that is consumed the most in the world is the Japanese Blue Crab or the Horse Crab.
6. Unlike most of the other creatures, crabs do not have separate thorax and abdomen. Rather, in most of the crabs, they are joined together and known as CEPHALOTHORAXES.
7. The male crabs have narrow abdomens, while the female crabs have broader abdomens.
8. Japanese Spider Crab can have a walking leg span of 3 to 4 m, which can go to 8 m when outstretched.
9. Japanese Spider Crab is the oldest crab of the world and is also believed to be the most deep-living crab as well as the one with the longest lifespan.
10. The most colorful crab in the world is probably the Sally Lightfoot Crab. It has red, orange, yellow and white colors.
