It's difficult to say definitively which animals are strictly carnivores, as there are very few species that truly eat only meat. Even animals considered carnivores might occasionally eat plants or insects.

However, here are some animals known to be primarily carnivorous:

* Big Cats: Lions, tigers, leopards, jaguars, cheetahs, etc.

* Other Cats: Domestic cats, lynx, bobcats, etc.

* Canids: Wolves, dogs, foxes, coyotes, etc.

* Bears: Polar bears, brown bears, black bears (although they are omnivorous with a preference for meat)

* Whales: Killer whales, dolphins, etc.

* Sharks: Great white sharks, tiger sharks, etc.

* Birds of Prey: Hawks, eagles, owls, falcons, etc.

* Crocodiles and Alligators:

* Snakes: Constrictors and venomous snakes

It's important to note that even within these groups, there can be exceptions. For example, some bears, like the panda, have a primarily vegetarian diet.

Ultimately, it's more accurate to describe animals as obligate carnivores, facultative carnivores, or hypercarnivores, based on the proportion of meat in their diet and their physiological adaptations for consuming meat.
