An ocean (from Ancient Greek á½ ÎºÎµÎ±Î½ÏÏ, transc. OkeanÃ³s, the sea of classical antiquity[1]) is a body of saline water that composes much of a planet's hydrosphere.[2] On Earth, an ocean is one of the major conventional divisions of the World Ocean.
Iguanas are native to the jungles of central and south America, and the Caribbean. The iguana is a large docile species of lizard, meaning that iguanas are often a popular choice when keeping exotic pets.
Because the marine iguana is ecothermic the ocean is cold enough to immobilize the lizard if it is immersed too long. This unique species has adapted to very different temperature variations. The marine iguana is an endemic species to the Galapagos Islands. These islands are located between 600 and 700 miles west of Ecuador in equatorial waters.
