Seals
Seals are carnivorous animals that live partly in the ocean and partly on land. Most seals come on land to mate and to shed their hair. But, seals can live up to 90% of their life in the water. So, they have webbed feet for swimming.
Seals eat fish, squid, molluscs and zooplankton. Incredibly, seals can also kill and eat penguins and other seals! Unfortunately for seals, sharks, killer whales and polar bears eat them.
Oil spills can have a direct effect on seal colonies. Toxic chemicals will be taken in by the seals because they have eaten food with toxins in it. These toxins can eventually get into the blood stream making them prone to disease and death. Seals are also often caught in nets! So, humans need to be careful not to disrupt seal populations!
