What is the spider's crab?
The spider crab is a member of the crustacean family Madijae , which includes about 700 kinds of crabs. The common properties of these crabs are the body that is slightly longer than wide and the legs are very long. These characteristics are what gave the crabs its common name "Spider Crab".
The largest kind of crab spider is macroheira kaempferi or Japanese crab spider. This crab has the longest legs of all known arthropods and these legs can move up to 12.5 feet (3.8 meters). The Japanese crab spider usually lives as a carnivore and catches meat from the Dead Sea creation. Although it is originally from southern Japanese seas, it is not strongly hunted - most crabs of caught disintegration only between 3 and 7 feet (about 1 and 2 meters), while larger crabs remain alone. These crabs can live for 100 or more years.
Another widely known type of spider is Maja squinado or European spider Crab, which usually live in the mud of soft sea beds. These crabs are much smaller than their Japanese PROtěšky, diameter as little is 0.7 feet (about 22 cm) and live only five to 10 years. The European spider crab also lives on an all -powerful diet with a wide range of foods such as algae, mussels and plankton. It also differs from Japanese diversity, these crabs are commercially hunted, at least 70% of the annual catch is found off the coast of France.
with 700 or more types of crab spider can be difficult to explain every species. While most have barbed exoskeletons, very long legs and long body, there are some that do not look much different than other types of crabs. However, all the spider crabs have 10 legs with the first two tilt in claws. Many use the spine and hooks on their backs to deliberately attach seaweed, dead creatures and other remnants for other camouflage. These species can be found around the world, some even discovered in the depths of Antarctica.
as many as manyAbout crustaceans, spider crab passes through the phase melting because it grows its "shell". This happens throughout his life crab. The mating season may not be the same every year because it starts as soon as the female crab melts. The egg fertilization takes place internally and then the woman puts them in shallow waters with lots of weeds and rocks to protect them.
