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.

There are three main species of black widow spider, all of which have very similar characteristics and inhabit areas in Northern America and parts of Mexico. Until very recently all three species of black widow spider were classified as one but recent research shows that as the species inhabit different areas, the three species of black widow spider have adapted to their environment in different ways.
The Northern black widow spider is primarily found in the north east of the USA and parts of south east Canada, although the range of the northern black widow spider overlaps with that of the western black widow spider a great deal.
The Western black widow spider inhabits areas of t
