Crab Scientific Name Since there are so many different kinds of crabs, they have thousands of common names, such as king crab , horseshoe crab , blue crab, snow crab, coconut crab, and more. Crabs can also have smooth shells or they can be covered with spiny bumps that deter predators or help them hide in coral reefs or rocky niches. Crabs tend to be aggressive towards one another, and males often fight to gain access to females. Some live in the water all of the time, while others live at the edge of the water, in and among the rocks or the sand along the shores. The Kapsiki people of North Cameroon use the way crabs handle objects for divination. Most species of crabs live from three to four years, during which time they must evade predators, find food, molt, and reproduce. Some crabs live exclusively in the ocean, while others live along the shoreline, and some crabs live in freshwater instead of the saltwater environment of the ocean. Regulating the amount of crab caught each season helps to control their numbers and make sure that crab continue to be around in the future. Crabs also eat algae, mussels, barnacles, clams, seahorses, and even smaller crabs. They eat algae and other plant matter as well as hunting animal prey. The scientific name for these little creatures would be Brachyura. green crab scientific name MINS | Uncategorised In North America and South Africa, it bears the name green crab or European green crab. A Lot of Crabs! In general, a crab has a rounded or oval-shaped body that is sometimes smooth and sometimes covered with protrusions of varying lengths that offer the crab some protection from predators.Crabs have ten legs, five along each side of the body. Decapods occur in all oceans, in fresh water, and on Crabs are found in all of the world's oceans, while many crabs live in fresh water and on land, particularly in tropical regions. :28–29, 99, Crabs are omnivores, feeding primarily on algae, and taking any other food, including molluscs, worms, other crustaceans, fungi, bacteria, and detritus, depending on their availability and the crab species. Mud crab scientific name is Scylla serrata which known as one of the most popular crab to be consumed due to the incredible big size and nice taste. Crabs typically live around water, especially saltwater or brackish water.  The evolution of crabs is characterised by an increasingly robust body, and a reduction in the abdomen. Spider crabs, which have thick, rather rounded bodies and long, spindly legs, are generally slow-moving and sluggish. William Parsons, 3rd Earl of Rosse drew the Crab Nebula in 1848 and noticed its similarity to the animal; the Crab Pulsar lies at the centre of the nebula. This is especially common in species that have one very large claw, or pincer, such as the fiddler crab.  Indeed, surimi is an important source of protein in most East and Southeast Asian cultures, appearing in staple ingredients such as fish balls and fish cake. It is an important species for fish industry because it sold in high price. Hermit Crab Scientific Name. Often, they seek the water to breed, and the babies are born there and live in the water until they are developed enough to come out onto the land. The largest crab is the Japanese spider crab, which can grow as much as 13 feet (4 m) wide when its legs are spread – about the length of a Volkswagen.

When preparing for moult, the old shell is softened and partly eroded away, while the rudimentary beginnings of a new shell form under it. However, sometimes the color is very distinctive, such as with the bright red Christmas crabs from Christmas Island. Click on a scientific name below to expand it in the PLANTS Classification Report. They were previously thought to be a monophyletic group, but are now believed to represent at least two distinct lineages, one in the Old World and one in the New World.
