Question

What animals have been known to be cannibals, particularly ones that are normal to the species?

Answer 1

humans, some monkeys. In many species a male will eat any babies not sirred by him

Answer 2

I think the most obvious animal-cannibals are scavengers; so vultures and hyenas.

Hope this helps! :D

Answer 3

Sand Goanna's will eat each other.

I think that Death Adders and Whip Snakes will eat each other too.  

Big roaches will eat each other if they are trapped with no food.

Answer 4

Humans, some species of spider (female will eat male after mating), some species of shark will eat their own young on occassion, as well male lions.

Carrion species, for example crows, will obviously eat anything including thier own. The same goes for pigs.

Answer 5

many, many species eat their own kind -

lions, sharks, spiders, chimpanzees, men, are just a few.

It might be easier to ask which carnivoruous or omnivorous species do NOT, at some point, eat their own
