Alien (Subnautica)

It's not really an alien, he's kind of a jumper of the Covenant, he travels through portals, can be found everywhere except for the initial biome and the Islands, it is not of the race of aliens, just a highly developed animal

This is one of the species created by the Forerunners
PS, this location is not modified, and this appears out of nowhere. In the last version (before the update with the tower defense) - was the same cave without warper
