Thermal Lily

The Thermal Lily is a flora species that will appear in Subnautica: Below Zero.

It has been stated that it is farmable, growing fruit that can be picked. It also acts as a heat source for the player and grows within caves above water.

Appearance
The main body of the plant consists of an eight-pointed star shaped structure, dark pink in colour with a yellow core that lightens towards the centre. In the middle of the core is a diagonal black cross. The main body of the plant is anchored to cave walls by a thick stem with a tough top side a fleshy dark pink underside.

Three points on each side of the main body bear large transparent "petals", with the uppermost and lower points remaining uncovered. Within the petals, the petals extend into long tendrils that extend outwards before looping back and connecting back to the main body. It appears when nearby movement is detected these loops glow and emit heat.

Behaviour
Based on the concept art, it appears that in their resting state the plants face upwards towards the sun in order to gain sunlight. However it appears they react to nearby movement, twisting round to face the source of the movement and emitting heat. This may act as a deterrent to potential predators or potentially encourage them to seek shelter in the warmth rather than eating the plant.
