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
Falcons are medium sized birds of prey found all across the world although falcons tend to prefer the more temperate regions of the Northern Hemisphere. Falcons are best known for their ruthlessness and their incredible flying abilities.
Falcons have tapered wings that allow the falcon to change direction extremely quickly especially when compared to other birds. Falcons have been recorded diving at speeds of up to 200mph, meaning they are the fastest creatures on the planet!
There are more than 40 different species of falcon that can be found all around the world such as the peregrine falcon and the black falcon. Falcons vary in size from 25cm tall to more than 60cm tall, but th

The horn shark is a small species of shark, natively found in the coastal waters of north-west North America. The horn shark is named for the broad, flattened head and high ridge found behind this shark's large eyes that is almost horn-like in appearance and makes this shark one of the hardiest of all shark species.
