Dead grey whale (Eschrichtius robustus) on a beach. This species of 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. Whale carcasses are sometime washed up on beaches, and live strandings occasionally occur due to rough weather, navigation errors, illness or injury. Photographed in Baja California, Mexico.
