2 Module Overview For the past 8,000 years, the ice cores of Antarctica and Greenland indicate that Earthâs climate has been unusually stable. Yet global climate has changed several times in Earthâs geological history, sometimes at a relatively abrupt rate, as shown by the Greenland ice core data. In the module, Temperature Over Time, you compared temperature patterns and trends over different time scales and regions.
It feeds on a wide variety of creatures. Smaller seals probably eat mostly krill, but also squid and fish. Larger leopard seals probably switch from krill to more substantial prey, including king, adelie, rockhopper, gentoo, emperor, and chinstrap penguins, and less frequently, other seals, such as crabeater seal.
They are extremely powerful seals and that is part of why they are such great hunters. They have very sharp teeth and they are also the fastest of all the seal species out there. In addition to consuming other seals they love to eat penguins as well while on land. They consume a variety of fish as well in the waters. The only predator that they have in nature is the killer whale. Ross seals also live in the colder regions but they are very unknown.
