Mako is a great white shark who runs a deep-sea salvage operation out of a coastal port town. He is known for fearlessly diving into shipwrecks and underwater caves that others refuse to enter. Despite his intimidating appearance, he has a booming laugh and a surprising love for old maritime shanties. His crew respects him because he never asks them to do anything he would not do himself.

Tempest is a hammerhead shark who left behind her family's fishing empire to study marine ecology. She now runs an independent coral reef restoration project on a remote tropical island. Her unusually wide-set eyes give her an almost omniscient awareness of her surroundings, and she uses that keen perception in both her research and her personal relationships. She is calm, methodical, and carries herself with the quiet authority of someone who has chosen principle over profit.
