5 Interesting Facts About Kroyer’s Deep Sea Angler Fish

Kroyers Deep Sea Angler Fish

Here is a Kroyer’s deep sea angler fish showing off his lure

Today I want to write about one of the weirdest animals in the ocean, Kroyer’s deep sea angler fish.

Here are five interesting facts about them:

  1. The females of this ugly fish are much bigger than the males, growing up to 1.2 metres long, while the males only grow about 16 cm long.
  2. Kroyer’s deep sea angler fish are ambush predators have a lure that hangs over their head and lights up in the dark deep ocean.  This lure can be moved around to attract their prey which they suck into their huge mouths.
  3. The light in the lure comes from tiny bacteria called photoplankton.
  4. The males and females have one of the strangest relationships in the animal kingdom.  When a male finds a female, he bites into her side and fuses to her forever, taking nutrients from her blood and fertilising any eggs that she produces.  This saves the species from having to find each other at breeding time, which is very difficult in their dark habitat.
  5. Kroyer’s deep sea angler fish have a very wide range and are found in very deep water from 400-2,000 metres below the surface in the Pacific, Atlantic and Indian Oceans.

I hope that you found these facts interesting and learned something new.
