What Are Some Common Animals Around the World?

Some common animals around the world include fish, mice and snakes. These animals are found in nearly every continent. Fish are found all the seas of the world. The exceptions are snakes, which are not found in the Arctic or Antarctica, though they hibernate in places with cold winters.

Fish live anywhere from shallow, fresh water pools to the depths of the ocean. They are found in the cold waters of Antarctica and the warm waters of the Caribbean. Their skeletons can be made from cartilage, as is the case with sharks and rays, or bone. They are tiny or can grow to over 50 feet long, like the whale shark. Other examples of fish include barracudas, salmon and goldfish.

One of the most successful mammals, mice are found nearly everywhere on Earth. They are even found in Antarctica. They are small rodents that grow between 2 and 6 inches long and weigh between 3.2 and 6.4 ounces. They live between 2 and 5 years. There are about 40 species of mouse.

Snakes are reptiles. There are close to 3,000 species of snake, and they range in size from about 4 inches in the case of the Barbados thread snake to over 30 feet long in the case of South America's anaconda. Some snakes are venomous and dangerous to human beings.
