Subnautica Wiki

The Spinner Fish is a fauna species of Subnautica: Below Zero. It was originally shown in concept art for the first Subnautica, but has now been repurposed as a Below Zero creature.


The Spinner Fish has a roughly spherical body with six fleshy protrusions sticking out at 60 degree intervals down the midline of its body. A large portion of the body near the top is pink and dotted with pale blue patches, while the rest of the body is colored yellow. A pair of small eyes with black pupils and multicolored sclerae are situated towards the front, with three siphons above each eye through which water is pumped for movement.


The Spinner Fish is a small herbivorous prey species with a peculiar method of swimming. Rather than using fins to propel itself through the water, the Spinner Fish instead uses three pairs of siphons on either side of its body for jet propulsion. As these jets are angled downwards the Spinner Fish spins around vertically when moving. What benefit this provides is unknown.

The Spinner Fish's appearance was likely inspired by the larval form of the ocean sunfish. Its arms also resemble Sea Stars.

The concept of a spiny-looking creature that moves very quickly with a rolling motion may be inspired by Sonic the Hedgehog.
