How do sharks hunt at night?
Midnight Cravings? When great white sharks hunt from below in daytime hours, they spot their prey by silhouette against the lit background above them. Mosselbaai’s seals use the cover of darkness to swim to their hunting waters and back—perhaps to avoid being easy targets for sharks.

Ovoviviparous shark pups depend on yolk for nutrition, and when an embryo has expended its own yolk sac, it turns to the eggs around it. Some species practice intrauterine cannibalism, or eating the other fertilized or unfertilized eggs in the womb. The best-known intrauterine cannibal is the sand tiger shark.

What is a sharks sixth sense called?
Except they have a sixth sense, called the Ampullae of Lorenzini which are first described in 1678 by researcher Stephan Lorenzini. Sharks have a network of special cells that can detect electricity, called electroreceptors, in their heads. They use them together with the olfactory for hunting and navigation.
