The Galapagos tortoise (giant Galapagos tortoise) was first documented by Charles Darwin last century when he went on his trip to the Galapagos islands.
The Galapagos Tortoise is the biggest species of tortoise in the modern world with some Galapagos tortoises reaching more than 4ft long! The Galapagos tortoise is also one the longest living species of tortoise with a number of Galapagos tortoises getting older than 150!
The Galapagos tortoise, like most other species of tortoise, is a herbivore spending its time grazing on grass and low trees. Today only 10 out of the 12 Galapagos tortoise species still exist on the Pacific islands due to the introduction of goats a few hundred
The Dusky Dolphin is a small species of dolphin that is found inhabiting the cooler waters along continental shelves throughout the southern hemisphere. This distinctive looking cetacean is closely related to other large marine animals including other dolphins, porpoises and whales but despite their fish-like appearance Dusky Dolphins are true mammals that both breathe air in and out of their lungs and also suckle their young on milk produced by the mother's mammary glands. Dusky Dolphins are widespread throughout the southern hemisphere with three species being recognised that have been grouped by their geographical range, with one found off the coast of South America, one near South Africa

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
