The Reginald is a common, passive, herbivorous fauna species.

Cooked and cured Reginald have the highest food value of any fauna, making them an excellent food source.

They are also useful as Bioreactor fuel, showing one of the highest power per unit ratios in the game.


The Reginald is characterized by its slim, dull green, yet tall body with two large eyes protruding from its sides. Its entire rearside is composed of one large, bioluminescent purple caudal fin.

Its front features a set of four small slits in place of a mouth.


The Reginald is fast and is mostly seen darting around the open space in various biomes, often forming small schools.

It is also a shy creature and will eventually flee from the player upon being noticed.

Reginalds can be found hanging around the fronts of Reefbacks in small schools of 4 or 5.
