A crab’s teeth is in it’s stomach. Crabs greatly vary in size. Smallest species, Pea Crab, reaches from 0.27 to 0.47 inches in length. Largest species, Japanese Spider Crab, has a leg span of 12 feet. Crabs have eyes on the stalks, just like snails. They can distinguish colors, but their eyes see a lot less details than human eyes. Crabs are omnivores (they eat both meat and plants). Crabs breathe with the help of gills. That is why they need to stay close to the water even if they live mainly on the land. Average lifespan of the crab is between 3 and 4 years. Pregnancy lasts one to two weeks and female deposits between 1000 and 2000 eggs.
