Mr Melonhead

I was doing some reading about whales, when I came across this little fella. He looked so happy, I thought I must write about him!

The Beluga whale is 1 of 2 members of the Monodontidae family and it shares this family with the unicorn of the sea, the Narwhal, and it is the only member of the genus Delphinapterus. The whale has a conservation status of near threatened; yet they are one of the most commonly kept whales in captivity due to their gentle and expressive nature.

The Beluga whale is found mostly in the Arctic, around the shores of North America, Greenland and Russia. It has a fairly wide diet, and tends to feast upon fish, crustaceans and deep-sea invertebrates.

In appearance the Beluga whale does not look like a 'normal' whale, it is all white in colour, and lacks a dorsal fin. Moreover it also has a large bump on its head, which is called 'the melon'. It is this 'melon' which allows the Beluga to use echolocation in order to locate other Belugas through sheet ice. Belugas vary greatly in size and can range from the size of a dolphin to the size of a small blue whale. They also have a lot of blubber and when well fed are almost spherical!

Although Belugas are able to see above water, their eyesight is not too great, however as their eyes have cone and rod structures, it is thought that they could potentially see in colour. These whales do not have a sense of smell, but they do have a highly developed sense of touch and they actually crave physical contact from other whales.

Explorer Fact: Beluga females give birth to a calf once every 3 years, with the gestational period being an average of 12-14 and a half months.
