10 Dumbest Animals in the World

Nurse shark

Given that many shark species need to keep swimming to breathe, you wouldn’t think them lazy, but the nurse shark is a different matter. They don’t migrate like many species and spend most of their time lying motionless on the seabed, an activity made possible by the fact they can actively pump water over their gills. Not needing to eat much to sustain their lifestyle, they spend much of the day sleeping and hunt at night for fish, molluscs and crustaceans. They’re not known for their hunting skills though and feed by sucking up their prey.
