Have you ever pondered upon the fact that carnivores don't eat other carnivores?

Some carnivores do, but it is true that most don’t seem to. If a carnivore goes after another carnivore, it would probably get more of a fight for it’s meal, since the other carnivore is designed to hunt animals too, not just plants. It’s probably just a matter of what’s easier.
Great White sharks generally kill with two hits to reduce chance of being injured or losing extra teeth. On the other hand, Tiger sharks just don’t care, and will happily eat other sharks.
Some Orcas have actually taken to eating Great Whites! They’ve figured out that when you tip a Great White upside-down, it essentially becomes paralyzed, making it an easy meal.

A carnivore that eats other carnivores is known as a tertiary consumer. Killer whales, polar bears, eagles, and wolves would all be examples. As @Prosb noted, however, hunting other carnivores is more difficult. It takes a lot of work to become dominant in an ecosystem’s food web, which is why there are different kinds of carnivores.

See also the Wikipedia article on trophic levels.

Actually,they do.
Coyotes in my neck of the woods kill and eat dogs and cats regularily.

As already mentione they do. However not all of them do. Maybe its because the meat is too gamey and they don’t have any meat tenderizer.

Maybe there’s something in the flesh of herbivores, or whatever isn’t a carnivore, (based on what herbivores and wtv else eat) that highly compliments the diet of a carnivore? I really don’t know…I’m also guessing as was already said; it’s probbaly harder to hunt down something that spends its life hunting.

They do eat other carnivores! Lions will kill and eat their own young, same with hyenas, chimps, bears, raccoons, foxes, rats. All kinds of creatures eat their own kind as well as other carnivores.

@Prosb Welcome to Fluther?

@Neizvestnaya I know that they will kill their young, for whatever resason, but I don’t know that they will eat them for nutritional value.

I agree with @Dutchess_III that we need to distinguish killing and eating as a matter of disposal from killing and eating as a matter of nutrition. Circumstantial cannibalism does not make something a tertiary consumer.

Very good question I was confused about this as well until I saw this documentary on Nat Geo wild. There was a hyena passing through a pride’s territory and she was killed by the lion.
The narrator said that the lions will not eat the hyena as a show of respect to a fellow carnivore or something along that line.

But there are plenty of animals which do eat their carnivores such as hyenas and jackals.

In that case they hyena was killed because it was competition. But I HOPE the narrator didn’t really say the lions would eat the hyena as a show of respect to a fellow carnivore! That’s just silly…for a lion!
