The Mesmer is an aggressive carnivore life form that could be found in the dark deep caves of the Subnautica game in certain biomes such as Kelp Forest and Bulb Zone. It is dangerous to approach it, as it has the ability of hypnosis, and it will lure you in, with yes.. swim towards it.. towards its beauty. Mesmer lures its prays with its small and colorful body, and four large skin panel wings capable of closing and opening like a peacock. Those four wings are green with purple stripes, patterns on those wings radiate and ripple mesmerizing its prey. A fanart Subnautica progress bar for YouTube with Mesmer.
