Appearance

The Spinefish closely resembles a Hoopfish in form, but has drastic differences in colouration:

  • Much of the body is translucent, with many white stripes arranged in a manner that resembles a ribcage. It also features small red spots around its eyes and near its tail.
  • Its eyes are yellowish green in color, and its caudal fin has a dull red hue.

Data Bank Entry

Spinefish Encyclopedia Entry

Spinefish

Small, school-mentality prey fish, closely related to the hoopfish.

  1. Grey Coloration: A combination of near translucent flesh with white, rib-like markings gives this fish a deathly appearance. It takes advantage of this to avoid the attention of its predators.
  2. Behavior: Moves in schools for protection, but will disperse and flee if necessary, whereon those fortunate enough to escape the gaze of their assailants will make for the sea floor and hide amongst the detritus.

Assessment: Edible (low calorie count)

Trivia

  • Although the databank entry states that Spinefish plays dead by laying on the seabed, this behaviour is absent in-game.
  • The databank entry also shows that the Spinefish is blind.
  • In early versions of Subnautica: Below Zero, the Spinefish spawned in the Methane Ice Caves biome, which was cut from the final release.
