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
The gila monster is a large species of lizard that is natively found in parts of the southern United States and northern Mexico. The gila monster is also one of only two species of venomous lizard found in North America.
The gila monster is found roaming through a range of habitats throughout the drier regions of central America. Gila monsters tend to inhabit areas that are more sheltered such as shrublands, woodlands, forests and semi-deserts.
In the same way that a camel's hump, the tail of the gila monster acts as a fat storage facility in order to help the gila monster to survive more successfully in such arid conditions. When the gila monster eats and therefore replenishes i

Ducks are omnivorous animals feeding on aquatic plants, small fish, insects and grubs both in and out of water meaning that ducks can easily adapt to different conditions. It is because of the duck's ability to eat such a diverse amount of food both in water and on dry land that makes ducks one of the most widespread birds in the world as they are found on every continent, with the obvious exception of Antarctica.
A duck's mouth contains rows of tiny plates that line their teeth, to help th
