The genus blind sharks ( Brachaelurus ) belongs to the nurse shark-like (Orectolobiformes) and is placed in the monotypical family Brachaeluridae. It includes two species, the blind shark ( Brachaelurus waddi ) and the blue-gray blind shark ( Brachaelurus colcloughi ). Both live on the coast of Australia from the water surface to depths of 110 meters.
features
Blind sharks grow to be 75 to 120 centimeters long. The number of vertebrae is 117 to 142. Your eyes are on the sides of the top of your head. The sharks are not actually blind, but the German vernacular name arose from the fact that the blind sharks caught by fishermen (probably for protection) close their eyes as soon as they are pulled out of the water. Your injection hole is large and the nasal barbels are very long.
