Mostly there are excotic animals e.g. Lions, tigers, monkeys, giraffes and gorrilas but they can have other animals such as birds and water animals :)
Yes, I have two eastern box turtles and two Russian tortoise's that live in the same enclosure.
Competition.
Two homonyms for "pen" are "pen" as in the tool used for writing and "pen" as in an enclosure for animals.
Two animals that compete with squirrels are rats and mice. They often live in the same areas and compete for food.
Quite a few animals don't live in Antarctia!
No because if two animals have the exact same scientific name then they would be the same animal.
Where two animals interact
Animals don't live together unless they are a family, husband, wife, kids. Its highly unlikly that two different animals are in the same family.
Two animals of the same class would have broader similarities compared to two animals of the same order. Animals of the same class share basic characteristics and evolutionary history, while animals of the same order share more specific traits and behaviors within a class.
It is possible for one snake to continue swallowing - taking the other snake in with the mouse. The solution is to never feed two snakes in the same enclosure at the same time !
No, these two animals cannot live together well. The turtle will often attack the crab in an effort to eat it, and it is not advisable for them to live in the same tank together.
Stripey animals.......
