Depends on the species of shark, and its size. The Red Finned shark in my aquarium is 3 inches long, and does not eat the same as a Great White Shark 20 feet long.
he can eat his wight in food
allot of food
whenever it really feels like eat needs food when the shark see it
whatever they find
200pd
As Much as it can eat!!!!! (2% of it's own body weight)
75,000,000 plankton in 1 hour
if you are asking can a shark eat another shark then yes because they do it for food
a food about a size of common human if you need to feed them you can just throw a nother shark in their and you can throw a hobo in their and pee on it
they eat crill
It all depends on the size of the family, how much they eat, and how often they eat.
Shark Food is scraps of human food like fish bones and mashed up body parts, if you are asking if humans eat sharks, yes they do predominately in Asia
