Finn whale.

The finn whale is the second largest animal on earth. They are found in every ocean on earth,  the west coast of Ireland is a great place to see them. November is the peak period for finn whales. The first sign to look for is the large column of steamy breath that they blow into the air as the finn whale exhales from its lungs. Common dolphins feed on the same prey as finn whales so are a good indicator if spotted. Dolphins will be seen coming to the boat as they swim in the bow wave that's created by the hull of the boat as it moves through the water.The dolphins move in front of the boat to save energy as they swim, but i also think they do it for fun as well. Good dolphin numbers show that there is lots of fish. The finn whale`s fin is about two thirds of the way along its back. They are dark in colour, they may be seen for a short while before they disappear to hunt below the surface, only resurfacing to exhale from their lungs before they dive down again. Very little is still known about these magnificent animals.
