I like to photograph all kinds of animals, both insects and mammals. These photos I save for the collection. Sometimes I upload these photos to social media to find out how are good my photos.
One of the photographs of the animal that I am portraying is a crab. There are several types of crabs that are already collections in my document. First the sea crab, and then the fiddler crab. Although in general the shape of crab is the same, but I see the difference of some crabs and fidle crab is from the color of their shells. This is what makes me interested to collect pictures of crabs, although until now not all types of crabs, succes to my photos.
Crabs are ten-legged animals. He entered the family of crustaceans. The crab has a very short tail, its stomach completely hidden beneath the chest (thorax). The body of the crab is protected by a very hard shell, almost like a turtle or a sea turtle. In addition, the crab body consists of chitin, and is armed with a pair of claws. Although there are certain types of crabs that only have one large claw and one small claw.
