Facial mimicry fish are a group of cold-water species whose dorsal or anterior tissues form human-like faces. Researchers provisionally call the structural effect facial anthropomimicry.[1, 2]
Anatomy
Cartilage, subdermal fat pads and modified denticle fields form brow ridges, a nasal bridge and independently mobile lip-like folds. False eyes in several individuals contain functional light-sensitive tissue. Whether this supports vision or display remains unresolved. The resemblance does not establish human ancestry.
Encounter conditions
Most reports concern winter nights at heated pools, quarry outflows and resort catchments where surface ice overlies unfrozen water. The animals surface, remain in place for minutes, then submerge without observed feeding or breeding. Most photographs were taken from directly above with consumer equipment.
Interpretation
The face is directed upward toward human observers, and the animals are described as too large to need the usual predator-deterrence explanation. Coincidental convergence and mimicry directed specifically at humans remain competing interpretations. No intact specimen has been recovered.
