Did you know there is a shark called Blind shark? Other than the Greenland shark who seems to become really blind once infected with a ophthalmic parasite, the Blind shark (Brachaelurus waddi) isn’t blind at all – it only protects its eyes by retracting its eyeballs and shutting its thick lower eyelids when caught.

Living solely off the eastern coast of Australia, the Blind shark is a nocturnal, bottom-dwelling species of carpetsharks. It likes rocky areas and seagrass beds in shallow coastal waters up to 360 ft -110 m- deep. Since it is easily trapped in tidal pools it is able to live out of water for up to 18 hours.

Blind sharks are up to 3.0–3.9 ft -0.9–1.2 m- long, but mostly much smaller. They mature at 24 in -62 cm- for males and 26 in -66 cm- for females. The females are ovoviviparous and give birth to 7–8 pups every summer. Newborns measure cute 5.9 to 7.1 in -15 to 18 cm- long. Despite being inactive and hiding during the daytime blind sharks are popular (and quite easy) aquarium fish. They are no danger to humans, but can bite if provoked and are then difficult to remove, due to their strong jaws.
