Ever wondered if an animal could have 10 eyes? This may appear to be an unknown fact for many, however, it is true. Even zoologists are astonished by the unique features of horseshoe crabs.
Every year in May and June, these animals crawl to the beach to mate and bury their eggs. Research reveals that this practice by horseshoe crabs is as old as 445 million years old. The crabs have survived four mass extinctions and are believed to be rare living fossils of their own kind. The crabs are also distinctly related to scorpions and spiders.
They usually copulate on the beach. During the epoch when horseshoe carbs were evolving, land animals did not come into existence. Therefore, their eggs, that were laid on the beach, remained safe and evolution continued.
Not many people know but horseshoe crabs are unique creatures with 10 eyes and carry blood that has saved innumerable human lives – including yours.
Every single crab is colored glossy green brown and has a shape of a shallow combat helmet. They are born with a six-inch long spine sticking out. Mostly, horseshoe crabs look alike, though males and females have many distinctions. The limbs of the males end in pincers while female carapaces are linked to thousands of pale green eggs.
According to a report, Conservation ecologist John Tanacredi, director of the Center for Environmental Research and Coastal Oceans Monitoring at Molloy College in New York,says,
These animals walked below the legs of brontosaurus at some point in time, they really should be the paradigm for survival and sustainability.
