Beavers are most well known for their distinctive home-building that can be seen in rivers and streams. The beavers dam is built from twigs, sticks, leaves and mud and are surprisingly strong. Here the beavers can catch their food and swim in the water.
Beavers are nocturnal animals existing in the forests of Europe and North America (the Canadian beaver is the most common beaver). Beavers use their large, flat shaped tails, to help with dam building and it also allows the beavers to swim at speeds of up to 30 knots per hour.
The beaver's significance is acknowledged in Canada by the fact that there is a Canadian Beaver on one of their coins.
The beaver colonies create one o
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

Electric Eels are found in the waters of South America, and are capable of generating a 500volt electric shock through 28ft of still water. The shock that the electric eel produces is enough to harm any large mammal, including humans.
Electric eels can grow up to 2.5 metres and only need to surface for air every 10 minutes due to the eels complex circulatory system. Electric eels tend to live in muddy beds in calm water, eating fish and small mammals.
Despite the name electric eel, the electric eel is actually related most closely to a catfish and not the common eel fish and many electric eel adults tend to be smaller than their eel fish counterparts.
