Jellyfish use stinging cells to protect themselves & catch food
Animals use or are born with camouflage this is to protect themselves against predators. Though some have this so they can easily hide and catch other animals to eat.
To protect themselves, like when they're in the arena. Or just to catch animals when they go hunting for food.
dolphins swim in pods to protect themselves and to catch food
They swim around the ocen and use it for how all other animals use energy
By running faster than the animals trying to catch them. Usually speed goes hand in hand with endurance, so an animal which is reasonably fast but also has a lot of stamina has a good chance of escape usually, if it's lucky.
Horses are not predators and are not carnivores. They don't have prey to catch. They can protect themselves from being preyed upon by running or fighting back.
Caecilians protect themselves by using camouflage to blend into their surroundings, some species also have toxic skin secretions to deter predators, and others can secrete a sticky, smelly substance from their skin when threatened to discourage predators from attacking.
The humans have build nature parks and catch poachers
In the ocean! They use their stinging tentacles to catch small fish.
They are a shoal fish, each with very sharp teeth. The natives do catch them for food. But I doubt if they need to protect themselves from natural predators - due to their ferocity when they smell blood from an injured animal swimming in the river.
no theyy onlyy eat fish small enough for them to catch and eat.
