The Anglerfish is a mutated angler fish that has been heavily disfigured by the Structure Gel leaks; losing its eyes and a skeletal human hand replacing its left fin while undergoing some other heavy mutations.
It is possible that the fused human face and hand belong to one of its previous victims and has been merged into the Anglerfish by the Structure Gel.
According to a log regarding the creature, it no longer hunts for normal prey like small fish, but rather "something not present in its ecosystem," which in this case heavily implies the the personnel of PATHOS-II and even Simon Jarrett himself.
The Anglerfish will lie still in wait and attempt to lure others to approach the light it is producing, an effective strategy due to the light beacons illuminating the way. The Anglerfish require a visual proximity in order to notice Simon then it will begin to swim towards Simon. If Simon gets too close the situation will result in the Anglerfish either knocking him out or killing him.
In order to reach Site Tau, one has to follow light beacons leading to a cavern in order not to be attacked by any deep-sea creatures. If one manages to follow the light sources and make their way to the cave, the light beacons are replaced with chemlights guiding and illuminating the path to the opposite side of the tunnel inside the cave.
At the exit, the light beacons' trail resume once again, but the Anglerfish lies in wait as the first light source primarily visible, baiting Simon to come near its light source. The Anglerfish will slowly swim toward Simon if he encounters the creature.
In this event, Simon should retreat to the chemlights inside the cave and wait for the creature to back out, then quickly run to the nearby light source until reaching Site Tau.
According to data collected from the populations of different species in 2100 forwards, this particular species is identified. For some reason, the rest of the Anglerfish's data is unable to be viewed.
