The Stalker is a rather large creature, possessing an elongated, smooth body with smooth skin. Its head features a long snout, which greatly resembles that of real life gharials.
Seven dorsal plates protrude from its back, running along the body from the neck to the tail. It has two pectoral and pelvic purple-tipped fins on each side of the body. The body ends with a broad, whale-like tail fin. It resembles some extinct marine reptiles.
The Stalker's dorsal side is blue-green in color, and is patterned in dark blue and purple, with a bright green and aqua underside.
The Stalker seems to have a fondness for metal; it will approach metal objects such as Metal Salvage, Silver Ore, and Titanium, pick the object up with its mouth and drop it again after carrying it for a short time. Sometimes when it picks an object up it will drop one of its teeth. It may also drop them when grabbing a Camera Drone or attacking a Seamoth. These teeth are required for creating Enameled Glass which is needed to make a Cyclops and other advanced objects. Stalkers will sometimes place metal salvage in a certain area with other pieces. The player can use this as a means of distraction to give the player time to escape so it is recommended to carry metal, or peepers when planning on entering the creepvine forests.
Stalkers can grab Camera Drones (as mentioned above), including ones housed in their sockets on the Scanner Room and will carry them in their mouths similarly to Metal Salvage. During this time the drones are incapacitated.
Being predators, Stalkers will attempt to chase and eat nearby Peepers and other small prey. They will also attack the player upon close encounters with each bite dealing 30 damage. The player should be cautious while exploring Kelp Forests to avoid getting attacked by surprise, as Stalkers often form small groups that will lurk in the dense Creepvines.
At night, besides being more difficult to spot due to being one of only two non-bioluminescent creatures in the game, Stalkers become more aggressive and have a wider aggressive radius, so it is advised to avoid swimming near Kelp Forests at night without adequate protection.
Stalkers can be found guarding or lurking near their Eggs and will attack if the player gets too close.
Spoiler alert: The following section contains story related material.
The Stalkers inside Primary Containment Facility's Aquarium are not hostile to the player, and are thus not a threat, although they will still steal cameras.
Interactions with the Player
It is possible to temporarily placate a Stalker by feeding them any kind of catchable fish. Doing this will pacify the creature for a short while, however this behaviour is temporary and the Stalker will soon resume its normal, aggressive behaviour. Stalkers hatched from an Alien Containment will remain passive, but will still steal cameras and attack the player's vehicles.
Data Bank Entry
A streamlined predator encountered in the kelp forests in wait of prey leaving the safety of the shallows to feed. The stalker likely carved out its evolutionary niche at the sweet spot between speed and size millions of years ago, and may be one of the oldest species on the planet.
The stalker appears to be attracted to titanium deposits, which tends to sharpen and put stress on its teeth.
As with many predators, it may be possible to temporarily distract hungry stalkers by feeding them.

Assessment: Stalker teeth may have applications in enameled glass fabrication
- As of 14.12.2014, the model of the Stalker was changed. Until then, the model of the Lava Lizard was used.
- The Stalker was also listed as Snout Shark in development documents.
- Stalkers and Lava Lizards are the only creatures that do not have some degree of bioluminescence.
- Although the Stalker cannot damage the Cyclops, it will attack it which normally results in the Stalker losing a tooth.
- Stalkers from the Kelp Forest can be observed wandering into the Safe Shallows quite often. Sometimes they will bump Lifepod 5 causing it to list slightly. Other times a few pieces of metal salvage in an area such as the Safe Shallows will result in a small group of them congregating to play with it which will create a small area dense with Stalkers and danger for an unprepared and sluggish player.
