Prince Aesril: Journey, V

Zealots were the ants of the sea. These magical creatures lurk under the deeps of the ocean. They moved in a group of not less than a dozen. Each group consists of one higher ranked. Their mandibles were able to chew wood if left unchecked, and their pincer-like limbs were used to crash their unfortunate prey. And since they lived underwater, where the light was barely a luxury, they were blind. Aside from their sensitive and slimy scales, they used their whiskers, attached under their jaws, to locate their prey. The closest resemblance to these beasts was cuttlefish's head and a body of an old and wrinkled frog ( spotted with black). They used their pincer limbs to climb the rope.

They built their nest near the Under Current. It might be their predator's instinct since ships, if not properly maintained, would have no chance at all to survive the bombarding pressure of the Current. Which leaves them with a wrecked ship and dead bodies floating in the sea.
