Sea Monkey Nests are natural structures found in Subnautica: Below Zero. The Sea Monkey has a habit of stealing interesting objects and returning them to its nesting grounds, therefore many fragments of Alterra technology can be found in their nests for the player to scan.
Up to three Sea Monkey Eggs can be found inside nests found in the Arctic Kelp Caves. Nests can be found prominently in the Arctic Kelp Caves and the Lilypads Crevice.
Few nests can also be found in some Arctic Kelp Forests
Appearance[]
The nests appear to be composed of packed sediment with plant matter intertwined to give structural support. Several large chunks of metal scrap can be seen embedded into the nest walls.
Databank Entry[]
| Sea Monkey Nest |
 |
|---|
Sea Monkey nests are large bowl-like structures made of packed sediment and plant matter. The sea monkeys use their wide flat tails to pack the materials and form the structure of the nest. Sea monkeys are naturally curious creatures often drawn to metallic materials, which they gather to reinforce the sides of their nests. |
| Source: Scan Sea Monkey Nests |
Sea Monkey nests which are scannable used to be identical to those that were not, but a scannable nest will now be "decorated" with a ring of components around its approximate midsection, either the thing that the scan is for (for equipment) or parts of the vehicle it is an upgrade for (Seatruck or Prawn Suit parts). The player needs to aim the Scanner at the components specifically to get the scan, not the body of the nest.
