The basking shark, the largest fish to reguarly occur in Canadian waters, is the second largest shark in the world, second only to the whale shark. This shark can range in length between 8 and 10 metres and is usually greyish brown in colour, often with a mottled or spotted appearance. Often, the basking shark is misidentified as another unusual shark, the Greenland shark.
Similar to the whale shark, the basking shark is considered to be a whale in the shark world. This slow-moving giant is a filter-feeder. In order to feed, basking sharks strain zooplankton and small crustaceans out of the water as it passes over their large gills.
