Grey whale blowhole. Close-up of a grey whale (Eschrichtius robustus) at the surface, showing its blowhole (on top of its head) and barnacles on its skin. Whales dive to feed, coming to the surface for air. This whale is found in coastal waters, migrating with the seasons from Arctic waters to tropical equatorial waters. It can grow up to 15 metres in length and weigh 16 tonnes. It feeds on crustaceans and worms extracted from seabed sediment. Photographed off Baja California, Mexico.
