  • Dolphin | Orca or Killer Whale (Orcinus orca)

  • Porpoise | Dall’s Porpoise (Phocoenoides dalli) & Harbor Porpoise (Phocoena phocoena)

 

dolphins vs. porpoises

Showcasing the morphological differences between dolphins & porpoises:

  • Body Size: Dolphins generally have larger, more elongated bodies than porpoise, with porpoise being quite petite in comparison to most dolphin species. (There are, however, exceptions!)

  • Beak: Dolphins generally have elongated snouts, or “beaks,” whereas porpoise have a shortened, blunt beak. (Again, you will find exceptions…)

  • Teeth: When in doubt, check those pearly whites! Dolphins have cone-shaped teeth, whereas porpoise have spade-shaped teeth.
