Cetaceans

Cetaceans are a civilization of heavily modified people who live underwater. The typical cetacean has two large sea eyes on the sides of their head, and two smaller land eyes positioned closer to the front. They have one lung and one gill, and can switch between the two with the use of a second epiglottis. They can also switch between vocal cords and underwater cords for a whale-song like type of speech.
== Behind the Scenes ==
In real life, Cetaceans are aquatic marine mammals belonging to the order Cetacea, which includes whales, dolphins, porpoises, and their ancestors.
Bach based the appearance and concept of the Cetaceans in part on Abe Sapien from the Hellboy films and comics.
