Ceadeus

Ceadeus is an Elder Dragon introduced in 2009 video game called Monster Hunter 3. Ceadeus resembles a giant whale with a face similar to a Dunkleosteus. It has a prominent beard of fur and two massive horns, which constantly grow and eventually overtake the creature’s eyes, leaving it blind. Luminous organs line the monster's underside, which turn from blue to red when it is enraged. The Ceadeus is known to be a rather peaceful creature until provoked. They do not bother humankind unless they feel threatened. It resides in a series of underwater canyons and ruins deep below Moga Island, but is unable to travel onto land.
