Would you expect the RBCs of a blue whale (Balaenoptera musculus) to look more like the typical mammalian RBC, or would you expect differences like those seen in the even-toed ungulates (camels etc.)? Why?
  1. Typical - There's no particular reason a blue whale would look different from the typical mammal
  2. Different - They should have RBCs with nuclei and organelles like fish RBCs, since they are also aquatic and breathe water.
  3. Different - They should have much larger RBCs, since RBC size scales with body size.
  4. Different - They might look more like an ungulate's RBCs since they are closely related species (Super Order: Cetartiodactyl).
