There are many different species of fish that exhibit mouthbrooding behavior, but some of the most common include:
* Cichlids: Many cichlid species, particularly from Africa, are known for their mouthbrooding behavior.
* Tilapia: Another popular freshwater fish that is known for mouthbrooding.
* Cardinalfish: Marine fish that are known for their mouthbrooding males.
How it works:
* The female fish lays her eggs, and the male fish often fertilizes them.
* Depending on the species, either the male or the female (sometimes both) will pick up the eggs and hold them in their mouth until they hatch.
* The parent fish will continue to protect the fry (baby fish) in their mouth until they are large enough to fend for themselves.
This behavior is an amazing example of parental care in the animal kingdom and is a fascinating adaptation for survival!
