Facts about Anglerfish Luring Techniques
- 05
Anglerfish luring techniques are found exclusively in females because males are too small and instead rely on females for nutrients after parasitic attachment.
- 04
Bioluminescent luring in anglerfish is an example of aggressive mimicry, where a predator uses a deceptive signal to attract rather than avoid prey.
- 03
Some anglerfish species vary the movement of their esca to mimic the swimming behavior of small prey, actively manipulating the lure rather than holding it still.
- 02
In deep-sea anglerfish, only females possess the illicium, the elongated dorsal spine that extends over the head to dangle the bioluminescent lure in front of prey.
- 01
The glowing lure of female anglerfish, called an esca, produces bioluminescence through symbiotic bacteria hosted within the bulb.
