This article is about the Lava Larva. You may be looking for the Lava Lizard.

The Lava Larva is a mid-sized, parasitic fauna species.


The Lava Larva has a dark violet body, which is slightly flattened on the top and underneath. It has a striped pattern on the back.

On the front, the Lava Larva has two short, bulbous antennae-like appendages pointing forward. It has a pair of useless eyes surrounded by an orange ring. A glowing, orange-colored pattern rims the creature's mouth and stretches all the way to the other end of its body.

While moving, the Lava Larva emits black particles from its back; these dissipate after a short time.


The Lava Larva will swim around aimlessly and flee from potential threats while producing high-pitched chirping sounds. It will attach itself to the SeamothPrawn Suit, and Cyclops, draining Energy and slowing the vehicle down.

The more Lava Larvae there are attached, the more quickly the energy will drain. In order to get the Lava Larva off, the player must hit it with the Knife, freeze it with the Stasis Rifle, or blast it off with the Propulsion Cannon or Repulsion Cannon. They can also be removed by the Prawn Suit Propulsion Cannon and are repulsed by the drill arm and will not come near the prawn if the arm is active, they will not approach and attach to a Cyclops with an active Cyclops Shield Generator, and can also be scared off with the Seamoth Perimeter Defense System. A Grav Trap will also drag them away from vehicles. Lava Lizards will also eat the larvae off of the vehicle without causing any damage. If the vehicle's energy is turned off by removing all Power Cells, or the Power Cells are depleted, they will detach and swim away. Alternatively, one can just remove the active power cells, making the Lava Larva detach from the vehicle.

Lava Larvae on the Cyclops can present a real threat if gone unnoticed, as the cyclops can quickly run out of power without the player noticing. The damage indicator will show the location of any Lava Larvae attached to the ship, making removal easier.

Influence on Vehicles

Number of Lava Larva Time attached Energy Lost
1 33s 1%
2 18s 1%
3 12.5s 1%
4 9s 1%
5 6.5s 1%
6 3s 1%
7+ 1s 1%
  • If the number of Lava Larvae should exceed six, vehicles will lose 1% of energy every second.

Data Bank Entry

Lava Larva-0.png

A grub-like species which appears to lack sight and smell, but is able to sense and drain thermal and electrical energy in its immediate environment.

1. Suction Cup:
Capable of attaching to smooth surfaces and generating high-pressure suction. Will release if it comes under sufficient strain.

2. Torso:
Thick scales protect from extreme temperatures. The lava larva lacks a traditional digestive system, instead it powers its internal processes directly from the energy it consumes.

3. Behavior:
Attracted to energy sources of all kinds. Draws energy from its prey to survive.

Assessment: Avoid when piloting vehicles - Remove to conserve batteries



  • Despite being called a larva, the Lava Larva is not currently suggested to be the immature form of any known creature on Planet 4546B; presumably, this name is based purely on outward appearance.
