Shore Crab Amazing Life
Those Amazin Crustaceans
Love crabs? Who doesn’t! But how much do you know about crabs? Today, we explore the interesting life of crabs in this article. Hailing from the crustacean family, the crab comes in all manners of shapes and sizes. There are more than 4500 known species of crab out there, most of them living on the shores of salty and fresh (or both) waters, though some live underwater as well.
In addition, terrestrial and semi-terrestrial crabs live on sandy and rocky areas. However, considering that crabs breathe with their gills, they need to stay close to the water even if they live on the land.
They also have a cool history. Crabs first appeared on the scene two hundred million years ago (i.e. the Jurassic Age). Thousands of species continue to inhabit our shores and seas, but many crab species are endangered because of habitat loss, and especially because of hunting.
The defining feature of the crab is it’s “exoskeleton”, its shell-like external skeleton. This shell (or carapace) is made of chitin, which gives it the protective feature to secure the soft tissue under As far as their diet is concerned, crabs are omnivores, eating everything from bacteria and fundu to worms, mollusks and even other crustaceans.
A lot goes in the world of crabs. While some species live alone, others thrive in groups. Just like fish have schools, crabs have ‘casts’. Casts thrive as crabs live in cooperation, providing food and protection to their families.
Crabs use their pincers and claws to make different sounds, with which they communicate with each other.
The male crab waves with its swimming paddles, which is the art of seduction in the crustacean world. Mating occurs mostly when the water temperature and the temperature outside is high. The female crab is pregnant for up to two weeks and deposits up to 2000 eggs. Crabs usually live for 3 to 4 years.
