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.
What do Seals Eat? Seals find the foods that they need in the water around them, which is why you will only find them where there is plenty of water. Their primary sources of food include fish but they will consume just about any type of meat they can get in the water. Other types of food that they enjoy include squid, octopus, and shellfish. Sometimes food sources are low due to the big ships fishing for such items in the same waters as the seals hunt.
