Key identification features

  • Females have a rounded, globular, football-shaped body, dark brown to black, covered in small bony tubercles that give the skin a rough, studded texture
  • Large head with a wide gape and rows of sharp, inward-angled teeth
  • Short, sturdy illicium (fishing rod) tipped with a luminous esca, held forward in front of the mouth
  • Small, reduced eyes adapted to near-total darkness
  • Males are tiny, free-swimming, and never permanently attach to females, unlike some related anglerfish families
  • Body reaches roughly 15 to 60 cm in females depending on species

Common look-alikes

  • Whipnose anglerfish (Gigantactinidae): also carry an illicium, but theirs is extremely long and whip-thin, often longer than the body, versus the football fish's much shorter, stouter rod.
  • Other deep-sea anglerfish families: similarly globular, but distinguished by smoother skin lacking the football fish's bony tubercles, and by differing esca shape.
  • Coffinfish: share a rounded body and small lure, but have loose spiny skin rather than hard bony tubercles, and live in shallower water.

Where you'll see one

Football fish inhabit the bathypelagic zone of oceans worldwide, generally between about 1,000 and 3,000 meters, drifting in open water while dangling their glowing lure to attract prey in complete darkness.

Frequently asked questions

How do I tell a football fish from a whipnose anglerfish?

Compare the fishing rod: a football fish's illicium is short and sturdy, while a whipnose anglerfish's illicium is extremely long and thread-thin, often exceeding its own body length.

What skin feature helps confirm a football fish identification?

Look for small, hard, bony tubercles studding the skin; this rough, bumpy texture is distinctive to football fish compared to the smoother skin of many other deep-sea anglerfish.
