They live almost exclusively in the Southern Hemisphere, with only one species, the Galapagos penguin, found north of the equator.

Most penguins feed on krill, fish, squid and other forms of sea life which they catch while swimming underwater. They spend roughly half of their lives on land and the other half in the sea.

Land is often cleared for investment purposes due to pastureland prices exceeding forest land prices. In this case, large amounts of forest are torn down and replaced with savanna
