how big are anglerfish?

Anglerfish come in a variety of sizes, but most are relatively small fish. Here are some details on anglerfish sizes:

  • The largest species is the giant sea angler (Ceratias holboelli) which can reach up to 3.3 feet (1 m) in length. However, most are around 7.9-15.7 inches (20–40 cm) long.
  • One of the most commonly known species, the deep sea anglerfish (Melanocetus johnsonii), averages around 5.9 inches (15 cm) in length.
  • The smallest species is the pygmy anglerfish (Cryptopsaras couesii) which measures only 0.6 inches (1.5 cm) long.
  • Female anglerfish are generally much larger than males. Males are tiny in comparison and attach permanently onto females in a parasitic-like mating.
  • When the lure is included, anglerfish can appear quite large compared to their actual body length. But the bioluminescent lure accounts for a small portion of their total size.
  • Different species occupy varying depths of the ocean from shallow to very deep. The frilled shark, for example, lives at depths around 4200 feet.

So in summary, most anglerfish species are quite small, in the range of several inches long. But the group does include some larger predatory species that reach lengths of nearly 1 meter. The glowing lure protruding from their heads makes their appearance seem disproportionately bigger than their actual size.
