Peeper

The Peeper is a small, yet fast, passive fauna species. It could be considered the mascot of Subnautica. It is easily identified by its large, bright yellow eyes.

The Peeper will try to flee from most life forms bigger than itself, such as Stalkers or the player. They can be caught, though their speed allows them to easily outrun a poorly equipped player. With the use of a Grav Trap, Seaglide, Stasis Rifle or Propulsion Cannon, they can be easily captured.

Cooked Peepers have above average Food properties. For this reason, they are very useful for players in Survival mode, and are always worth the catch.

Appearance
The Peeper is small, with its body being mainly a bluish hue, turning more greenish near the tail. Its head is composed of a yellow, beak-like mouth on the front and a pair of large eyes situated on both sides of the head. The eyes feature black pupils with bright bioluminescent yellow sclerae and brown irises. It is also noteworthy that the Peeper has eyelids.

It has a small caudal fin. There are three holes running along on each side of the body that resemble gills. It has two tube-like organs that extend from its body to the top and the bottom of its head, resembling backward-facing jets, that propel it forwards, leaving water trails when it does so.

Behavior
The Peeper is mostly active during the day, and can often be seen jumping out of the water. At night, it seems to rest more, though it is still somewhat active. When chased by the player, the Peeper may sometimes shut its eyes, making it harder to be seen - it often does so at night, making it near impossible to find and catch in the darkness. It can be heard making chirping-like noises when swimming.

Peepers can sometimes be seen being chased by Stalkers, as they are their preferred prey.

Peepers can often be seen following close behind Reefbacks in groups of 3 or 4.

Garryfish: Shows no immunity to infection - death commonly occurs within 4 days. Does show limited symptom remission on exposure to emperor stomach enzymes, but symptoms quickly recur.

Sea Dragon Embryos: Adult specimen too large to study in containment. Egg specimens acquired from nesting site. Embryos show no signs of immunity - death commonly occurs within 3 weeks. Small sample of eggs has been retained for continued, high priority research on leviathan hatching mechanisms.

Peeper: Shows no immunity to infection. Shows advanced learning behaviors. Shows some capacity to transmit enzymes to other specimens.

Unidentified Leviathan: The closest translation of the alien symbol for this specimen is 'sea emperor'. Bone samples from deceased leviathan specimens indicate some potential for carar immunity. Single specimen captured for study at purpose-built emperor containment facility, constructed in volcanic region at depth 1200m.

PDA Assessment: While it is unlikely that the emperor specimen is still contained within the facility described, it may be possible to acquire there further data on their attempts to develop a vaccine.
