While all whales, dolphins and porpoises fall under the order of Cetacea, the orca’s teeth are what classify them under the suborder Odontoceti, making them “toothed whales.” The orca’s teeth can grow to be up to around four inches long.

Odontocetes typically do not engage in the dramatic seasonal migrations known for some of the mysticetes, although there are exceptions among the larger species. Healthy mysticetes never leave the water, nor do they attempt to leave the water, in favor of land.
Is Odontoceti a family?
Animals belonging to suborder Odontoceti are a very diverse group of cetaceans with the common, distinctive feature of having teeth. Suborder Odontoceti comprises 10 families, for a total of 72 species.
What is the difference between an Odontoceti and Mysticeti?
Whales in the Mysticeti suborder have baleen plates that serve as a filter-feeding system, while marine mammals in the Odontoceti suborder—which includes dolphins and porpoises as well as whales—have teeth.
Is a blue whale Odontoceti?

How much does a whale tooth cost?

What is the difference between odontocetes and Mysticetes?
Generally, odontocetes are smaller than mysticetes. Odontocetes are also more social than mysticetes, and live together in family groups called pods. While all cetaceans have two nostrils, odontocetes have a muscular flap covering one nostril. Thus, odontocetes only have one blowhole.
What does a dolphin’s teeth look like?

Do mysticetes migrate?
Most baleen whales are highly migratory, moving toward high-latitude (polar) feeding areas in the summer and toward low-latitude (tropical) calving areas in the winter.
What is a suborder Odontoceti?
toothed whale, (suborder Odontoceti), any of the odontocete cetaceans, including the oceanic dolphins, river dolphins, porpoises, pilot whales, beaked whales, and bottlenose whales, as well as the killer whale, sperm whale, narwhal, and beluga whale.

What are the 3 subgroups of odontocetes?

What is the difference between odontocetes and mysticetes?
How many species of odontocetes are there?
70 species
The members of this branch of cetaceans are generally much smaller than the baleen whales, but they are far more numerous. They all have teeth, and the number of teeth is variable. They comprise about 70 species in six families.
