The cuscus is a large marsupial native to the Northern forest of Australia and the large, tropical island of Papua New Guinea. The cuscus is a subspecies of possum with the cuscus being the largest of the world's possum species.
The cuscus is known to range in size from just 15cm to more than 60cm in length, although the average sized cuscus tends to be around 45cm (18inches). The cuscus has small ears and large eyes which aid the cuscus through it's nocturnal lifestyle.

Sharks are a group of fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Modern sharks are classified within the clade
Selachimorpha (or Selachii) and are the sister group to the rays. However, the term "shark" has also been used for extinct members of the subclass Elasmobranchii outside the Selachimorpha, such as Cladoselache and Xenacanthus, as well as other Chondrichthyes such as the holocephalid eugenedontidans. Under this broader definition, the earliest known sharks date back to more than 420 million years ago. Acanthodians are often referred to as "spiny sharks"; though they are n

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
