Spinner Fish

The Spinnerfish (Placeholder name) is a future fauna species of Subnautica: Below Zero. It was originally designed for the first Subnautica, but has now been repurposed as an Expansion creature.

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

The Spinnerfish's appearance was likely inspired by the larval form of the ocean sunfish.

Appearance
The Spinnerfish has a roughly spherical body with six fleshy protrusions sticking out at 60 degree intervals down the midline. The larger portion of the body is pink and covered with pale-blue patches. The rest of the body is coloured yellow. A pair of small eyes with black pupils and blue and green sclerae are situated towards the front and above each eye are three siphons through which water is pumped for movement.
