Umbcruel drifts on the ocean surface, communicating with one another over long distances at night with bright yellow bioluminescent flashes. The frequency and brightness of the flashes hold specific meanings that researchers are trying to determine.

Umbcruel floats on the ocean surface at night, with its yellow rings and orbs glowing brightly as it absorbs moonlight. It conjures tentacles of pure shadow which it uses to drag prey to its true mouth, hidden by the physical tentacles at its base.

It lives in complex rock formations on the ocean floor and traps prey using its 80 tentacles. Umbcruel evolved from exposure to the moon's energy pulses.
