Trivalve

The Amazing (And Frankly Adorable) Trivalve Wiki!

The Trivalve is a small fauna species that appears in Subnautica: Below Zero.

Appearance
From a side view, the Trivalve's body resembles a magatama, and it is mostly covered in a colorful exoskeleton. The creature has six visible legs, with four large ones supporting its weight, and two small ones right next to two pedipalp-like extremities. It has three eyes arranged in a vertical line, two small eyes for depth perception and a large complex eye between these two. Under the eyes is a beak-shaped mouth pointing downwards.

The Trivalve species appears to have two morphs that vary from each other in coloration. One morph has a shell that is pale orange on the top and darker orange on the sides and underside and black stripes, with the fins sharing the same coloration. The other morph is pale blue in color, with irregularly-shaped white stripes radiating outwards from the centre of the body.

The orange-shelled Trivalve has bright yellow eyes, whilst the blue-shelled Trivalve has slightly darker, more orange eyes.

The shell of the Trivalve, despite appearing similar to the hard shells of many invertebrates is actually soft and flexible, as shown by the Trivalve's animations.

Behaviour
The trivalve is very passive and playful towards the player, it can also interact with the player. Its Behavior is similar to the Cuddlefish from Subnautica.

Design
The body of the Trivalve looks very similar to the shell of nautiluses, the most basal of living cephalopods. The name Trivalve is inspired by the class Bivalvia, possibly suggesting some comparable anatomical features. The creature's ability to swim upside-down seems to be inspired by horseshoe crabs.
