or different shaped bodies. But there are also other fish

Interesting Facts and Information - Why are Pearlscale slimy?
Pearlscale secrete a type of mucus, or slime, from their skin.

the water faster. Some fish species also release
toxins in their slime which ward off enemy attacks. Other fish
species use their slime to feed their young.

Gills enable the Pearlscale to breathe. Gills consist of thin
sheets of tissue containing blood vessels. As water passes over

large bony plate called an operculum. Some fish species however
have lungs and breathe air.
