Pacific spotted ratfish (Hydrolagus colliei), or ghost shark
The Pacific spotted ratfish (Hydrolagus colliei), or ghost shark, lives in deep waters near the ocean floor and possesses strange morphologies like large, rabbit-like eyes and a giant bulb on the forehead of males that grows spiky teeth resembling shark teeth. Researchers are using remotely operated underwater vehicles to search for their nesting grounds to learn about the developmental processes that lead to these morphologies.
