IPA: /ˈmaʊθˌbriːdə/
KK: /maʊθˌbridər/
A type of fish that carries its eggs and young in its mouth for protection, commonly found in certain genera like Haplochromis and Tilapia.
The mouthbreeder carefully protects its eggs by keeping them in its mouth until they hatch.
Mouthbreeder → It is formed from "mouth" (from Old English "muð", meaning the opening of the face used for eating and speaking) and "breeder" (from Old English "bredan", meaning to produce or raise). The term "mouthbreeder" refers to an organism that carries and nurtures its young in its mouth.
Think of a creature that 'produces' ('breeder') its young in its 'mouth' — that's why it's called a mouthbreeder.
