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.


The Reginald is characterized by its slim, dull green, yet tall body which has two large eyes protruding from its sides. Its entire rear 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 shoals.

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 Reefback Leviathans in small shoals of four or five.
