1. The orca is classified as an odontocete, so we write: \[ \text{Orca: Odontoceti} \] 2. The beluga whale is a toothed whale and thus is an odontocete: \[ \text{Beluga Whale: Odontoceti} \] 3. The grey whale is a baleen whale, which places it in the mysticete suborder: \[ \text{Grey Whale: Mysticeti} \] 4. The blue whale is also a baleen whale, so it belongs to the mysticetes: \[ \text{Blue Whale: Mysticeti} \] 5. The narwhal, being a toothed whale, is part of the odontocetes: \[ \text{Narwhal: Odontoceti} \] 6. The humpback whale is a baleen whale and is classified as a mysticete: \[ \text{Humpback Whale: Mysticeti} \] 7. The bottlenose dolphin, a toothed whale, belongs in the odontocete suborder: \[ \text{Bottlenose Dolphin: Odontoceti} \] 8. The sperm whale, being a toothed whale, is classified as an odontocete: \[ \text{Sperm Whale: Odontoceti} \]
