The North Pole is called the Arctic and contains polar bears. The South Pole is the Antarctic. It has no polar bears, but many penguins. Both the Arctic and Antarctic are extremely cold, often averaging -40°C. In the Northern hemisphere summer the North Pole has has 24 hours of daylight and the South Pole experiences 24 hours of night. This is then reveresed during the Northern hempisphere winter.

Penguins at the South Pole have many of the same adaptations. In addition, the male Emperor penguins have evolved to insulate their egg on their feet throughout winter. This is a behavioural adaptation.

Deep sea volcanic vents

Deep sea volcanic vents are places on the ocean floor where the volcanic gases of underground magma chambers bubble through. These form plumes of gases which are very hot. These are extreme environments because of this heat and the high pressure that comes at the bottom of the ocean. They are utterly dark.
