River Prowler

The River Prowler is a large, aggressive fauna species that dwells exclusively in the Lost River.

Appearance

The River Prowler has a thin, elongated body with many protrusions coming from both the top and bottom and a spine-like structure visible within its transparent body. The head is fleshy red in color, featuring two round, yellow eyes, a large jaw with many visible sharp teeth, and four tendrils trailing behind its head.

The majority of the River Prowler's body, including the internal organs, is transparent, emitting a faint white bioluminescent glow. Part of its skeletal system is visible, although, oddly enough, none of its organs.

Behavior

River Prowlers are aggressive towards the player as well as small, medium and shark classified fauna. The predator attacks by lashing out its tendrils before biting for moderate damage. Despite living in caves, River Prowlers swim slower at night while docile. This does not impact their aggression range or chase speed. The creature will flee for a few seconds upon being struck once with the knife.

River Prowlers will target the Seamoth or Prawn Suit when the player is piloting them.

Like most carnivores, holding any fauna will cause the River Prowlers to eat the fish upon attacking the player, preventing damage from being taken. This will decrease the creature’s aggression for a short time.
