World Whale Day

These giants of the ocean are magnificent creatures. Whales belong to the order of cetacea – which includes whales, dolphins and porpoises. Of the whales there are two suborders: toothed whales and baleen. Baleen whales are the largest species of whale and have a comb-like fringe, called a baleen, on the upper jaw, used to filter plankton, small fish and crustaceans. Toothed whales have teeth and prey on fish, squid, other whales and marine mammals. They sense their surrounding environment through echolocation.

The blue whale may be the largest animal to have ever existed. These animals were much smaller, up until about 4.5 million years ago, when climate change increasing the food supply and causing a growth spurt – tripling their size. Their change lines up with the beginning of an Ice Age. As new ice caps formed, nutrients would have seasonally been washed into coastal waters, increasing the food supply.
