  1. Toothed Whales By: Lauren Granville

  2. There are around 70 different species of Toothed Whales. • Some Toothed Whales are: Sperm whale, Bottlenose dolphin, River dolphin, Beaked dolphin, Orca, Pilot, Narwhal, and Beluga whale.

  3. There is a wide distribution of Toothed Whales all over the world. • They can be found in deep water habitats, coastal shores, in Antarctic seas, tropical seas, and in fresh water. • Most migrate for food or to breed. Others, like the Sperm whale, are said to be the wanderers of the ocean because they inhabit oceans all over the world.

  4. Toothed Whales diet varies among the different species. • They actively hunt prey using echolocation. • Toothed whales have peg-like teeth for grasping their prey. • The whalesthat feed on fish, seals, and other whales, generally have more teeth than the ones that feed on invertebrates. DIET

  5. Orcas will strand themselves on a sandy beach in order to catch and eat seals. • Bottlenose dolphins will herd schools of fish up onto a mud bank, stranding themselves until they are finishedeating. Feeding Methods

  6. The melon is a fluid-filled structure, unique to Toothed whales. • Its located between the blowhole and beak and is believed to function in echolocation. • They use the melon as an adjustable acoustic lens. The melon

  7. The blowhole is usually located on the top of the head, except for in the case of the Sperm whale. • Sperm whales have a blowhole that is located on the front left-hand side of the head. • These whales are the largest in the Toothed whale group. Sperm Whales

  8. Dolphins and porpoises are aesthetically similar. Dolphins are more talkative and make whistling sounds through their blow holes for communications; porpoises do not. • Both are very intelligent. Dolphins and Porpoises

  9. This family, Monodontidae, has only two species: the Narwhal and Beluga whale. • Narwhal and Beluga’s are found in arctic seas and major rivers draining into them. • Both lack a dorsal fin. Narwhal and Beluga

  10. Whether whales sleep or not remains a mystery. • Scientists believe whales rest one side of the brain at a time. They do this by closing one eye at time before swapping to the other eye while swimming close to the waters surface. Do whales sleep?
