Are you asking which animals are predatory toward other animals? Which are predators? This question has a complicated answer. There are "top" predators like the big cats (tiger, lion, leopard, puma, etc.). They can prey on (hunt, kill, and eat) other animals which are considered their prey, but some of these prey animals (coyotes or hyenas, for example) might also be predators of smaller or weaker animals lower in the food chain, like deer, rabbits, mice or birds.
Some animals feed exclusively on plants. They are called Herbivores. An example is a horse. Some animals feed exclusively on meat. They are called Carnivores. An example is a lion. Some animals eat both plant and animals. They are called Omnivores. An example is humans.
they have their own way of comnunicating with each other for example the way humans talk
a specialized structure is something that a animal has that is for protection or something the some animals have that others animals don't have for example= ex:the long tailed salamander has no lungs
