Whether its size is caused by adaptation to the island's other inhabitants, or by cross-breeding with another larger species, Melanocetus Anglerpescum is the largest form of Anglerfish I've ever heard of. Typically found only among the deepest, darkest expanses of the ocean, this creature preys on smaller fish while being an excellent source of food for larger predators.

Melanocetus has an array of bioluminescent light pods at the end of stalks on its head. Like typical anglerfish, it primarily uses these to attract smaller fish and trick them into coming close enough for Melanocetus consume the prey. This often makes wild Melanocetus itself relatively easy to spot among the briny depths.


Exploring the depths of the ocean can be difficult. The cold, the lack of air, and the shocking absence of light combine to make travel very dangerous. A tamed Anglerfish can use the natural light at the end of its stalks to illuminate the depths, making exploration not only safer, but more lucrative. Furthermore, these luminescent noodles can be harvested to create long-lasting organic light emplacements for surface dwelling!

— The Dossier

The Melanocetus, more commonly known as the Anglerfish or Angler, is a small carnivorous fish found on the Ark.

Wikipedia has a more detailed and comprehensive article on Angler


The Angler is very unusual for an anglerfish. Firstly, it's as large as an ichthyosaur and very robust, unlike its small and fragile relatives. This may be an adaptation to the island's (relatively) shallow seas or an abundance of large prey. Males and females are almost identical, unlike other fish of genus Melanocetus. This fish has three bioluminescent lures on its head and an oversized mouth lined with needle-like teeth. Anglers are mainly deep-sea fish but occasionally venture into shallower waters at night to feed on small reptiles and seabirds.


The angler will attack the player and any tamed creatures, despite the dossier referring to it as generally skittish. When damaged in a fight, they will attempt to flee, but will turn around and attack again after a short chase.

Trivia not relevant for the game

  • The Angler's genus Melanocetus is a modern day genus more commonly known as the black seadevil.
  • In reality, the male angler fish is much smaller than the female, and attaches to the female, becoming a parasitic pair of gonads. This method is employed due to the darkness of the depths making it hard to find a mate.
