Papilloculiceps

Papilloculiceps is a genus of anglerfish in the family Linophrynidae. It is comprised of only two described species, both of which inhabit the deep waters of the Atlantic Ocean. These anglerfish are notable for their unique physical adaptations, including their bioluminescent lures and their ability to thrive in the extreme conditions of the deep sea.

Common Names

Members of the genus Papilloculiceps are commonly known as "bulbous-headed anglerfish" or "papillated-headed anglerfish" due to the distinctive bulbous shape of their heads.

Characteristics

Papilloculiceps species exhibit a range of characteristic features, including:

  • Bioluminescent lure: Like all anglerfish, they possess a bioluminescent lure that extends from their head. This lure serves to attract prey in the dark depths of the ocean.
  • Bulbous head: Their heads are distinctly bulbous in shape, a feature that gives them their common name.
  • Papillae: Their heads are covered in numerous papillae, which are small, finger-like projections. These papillae are believed to have a sensory function.
  • Small eyes: They have relatively small eyes, which are likely adapted to the low light conditions of the deep sea.
  • Large mouth: Their mouths are large and filled with sharp teeth, allowing them to effectively capture and consume prey.
  • Sexual dimorphism: There is significant sexual dimorphism between male and female Papilloculiceps. Males are significantly smaller than females and have a much reduced body size, while females are larger and more robust.

Environments

Both species of Papilloculiceps are found in the deep waters of the Atlantic Ocean. They inhabit the bathypelagic zone, which extends from approximately 1,000 meters to 4,000 meters below the surface.
