Interesting facts
Bristlemouths are the most numerous vertebrates on Earth, outweighing all wild birds combined!
Some species have transparent teeth, making them super sneaky when ambushing their tiny meals.
These tiny fish create their own light patterns to talk to each other and trick predators.
They live in perpetual darkness, where the sun's light never reaches and pressure is crushing.
Special abilities
Ability
Glow Camouflage
Bristlemouth has special light organs that help them blend in with faint sunlight from above, making them invisible to predators below.
Ability
Deep-Sea Commuter
Bristlemouth can migrate hundreds of meters up and down the water column each day, following tiny prey to shallower waters.
Ability
Big Mouth Hunter
Bristlemouth has a very large mouth and sharp, bristly teeth that help them ambush and catch small prey in the dark ocean depths.
