Gerbils are naturally found in the sandy plains of Africa, Asia and the Middle East. The gerbil was originally known as a desert rat until they were commercially introduced to North America and bred as pets.
The gerbil is a small rodent, similar in many ways to by the mouse and the hamster. Gerbils have a long tail like a mouse which the gerbil is able to shed should the tail get trapped. This self defense mechanism allows the gerbil to escape predators, leaving them with just a tail.
Gerbils have sharp claws which the gerbils use to burrow their way into the sandy grounds of the desert. The gerbils are also able to use these underground burrows to get away from danger by quickly
The Capybara is a large, semi-aquatic rodent that is found inhabiting the water-logged regions of Central and South America. Closely related to other South American rodents such as Chinchillas and Guinea Pigs, the Capybara is the largest rodent in the world weighing up to 75kg and measuring nearly 1.4 meters long. Despite their enormous size though, these mammals have adapted well to life in the water and have a number of distinctive characteristics that aid their amphibious lifestyle, including the webbed skin between their toes which is particularly helpful when swimming. Interestingly enough, the common name of the Capybara is thought to mean "Master of the Grasses", whilst it's scientifi

There are around 100 different species of angelfish that inhabit the waters of the southern hemisphere. There are two main types of angelfish, those that live in the freshwater rivers in South America (freshwater angelfish) and those angelfish that inhabit the salty ocean waters (marine angelfish).
The freshwater angelfish has a more triangular shape and will generally only grow to a few inches in length. The marine angelfish can grow up to 12 inches (the same length as a big ruler) and generally have very brightly coloured markings but the exact colours depend on the angelfish species.
Both the freshwater angelfish and the marine angelfish are known to be relatively difficult fi
