Oarfish

The Oarfish is an enemy that spawns in the 2nd and 3rd layers of the Abyss. It is a long enemy with multiple segments. Like most Abyss enemies, it won't attack the player unless they get too close or they attack it. It attacks by using its very long body to trap the player.

Trivia

 * Oarfish in real life live in deep sea away from turbulent, shallow water. The name likely refers to the discarded belief that the fish use their pelvic fins to "row" through water.
