The Humpback Whale
The humpback whale is one of the bigger species of whale with the average adult humpback whale measuring more than 15m long (thats still about half the size of the blue whale).
The humpback whale is a species of Baleen whale and is thought to be closely related to the blue whale and the minke whale. As the humpback whale is a type of Baleen whale, this means that the humpback whale has rows of plates in the enormous mouth of the humpback whale, which the humpback whale uses to filter small particles of food out of the water. The humpback whale therefore does not have teeth.
Humpback whales primarily feed off krill and plankton that are present in their billions in richer waters. The humpback whale will also eat small fish and crabs that get taken into the vast mouth of the humpback whale when the humpback whale is filtering large amounts of water in order to extract the nutrients from it.
The humpback whale has not one but two blow holes, which are located on the top of the humpback whales head. The blow holes of the humpback whale enable the humpback whale to breathe in air on the surface of the water. Humpback whales spout (breathe) around 1-2 times per minute when the humpback whale is resting, and 4-8 times per minutes after the humpback whale has made a deep dive into the ocean. The blow of the humpback whale is a double stream of spray that rises between 3 and 4 meters into the air above the surface of the water.
Humpback whales are often seen migrating together in large pods but the relationships between groups of humpback whales are thought to be temporary and only last for a number of days. Humpback whales are also highly acrobatic animals and are often a favourite with whale watchers as the humpback whales can launch themselves high above the surface of the water.
