Study: Polar Bear Populations Have Plummeted 40 Percent in Alaska and Canada Previous studies linked declines in summer sea ice due to warming temperatures to “reduced physical condition, growth, and survival of polar bears,” the report said. Polar bears depend on sea ice to let them travel across the frozen water to hunt for seals—their preferred diet—that emerge through cracks in the ice to breathe. The study found that low survival rates from 2004 through 2006 led to a 25 to 50 percent decline in the number of bears in the region.

Meet the toughest animal on the planet: The water bear that can survive being frozen or boiled, float around in space and live for 200 years (shame it isn't much to look at) Molting Water Bear or Tardigrade with an egg mass. Water Bear's can surivive 5,700 grays of radiation, when 10-20 grays would kill humans and most other animals. This Tardigrade or Water Bear is infested by fungi. The animals can also live for a decade without water and even survive in space.

The Polar Bear Habitat Polar bears prefer the ice packs to other parts of their habitat because it allows them to remain in close contact with their main food source. Seals. Polar bears will remain in this ice pack habitat all year. They prefer the sea ice over all other places. When summer comes, and the polar regions warm up, the polar bears will travel many miles to remain on the ice, near their food source, seals.

KidZone Animal Facts The Polar Bear Polar bears have wide front paws with slightly webbed toes that help them swim. They paddle with their front feet and steer with their hind feet. Paw pads with rough surfaces help prevent polar bears from slipping up on the ice. Polar bears have been known to swim 100 miles (161 kilometers) at a stretch. Polar bears primarily eat seals. They often rest silently at a seal’s breathing hole in the ice, waiting for a seal in the water to surface. Once the seal comes up, the bear will spring and sink its jagged teeth into the seal’s head.

- Most polar bears remain with the pack ice as it recedes north during the summer melting season; however, along Alaska’s Beaufort Sea coast, some polar bears also come on land to rest until shore-fast ice begins to develop along the coast in late fall and the pack ice advances south, once again providing them with a suitable platform for hunting seals.

Indestructible 'water bear' bug that can survive in space could revolutionise computing Microscopic animals known as water bears, or the the more formal name of tardigrades, have a remarkable ability to withstand extreme environments of hot and cold, and even the vacuum of space. Their results potentially offer a simple way to improve the efficiency of electronic devices such as light-emitting diodes, optical fibers, and solar cells.
