Stay-at-home fish more diverse but more vulnerable

Egg-guarding fish are more likely to yield new species, but their disconnect from other fish populations makes them more vulnerable.

The study of diversity patterns among 7000 fish species over the past 100 million years will offer conservationists a new insight into ecosystem connections.

University of Queensland researchers compared egg-guarding fish species to those that release eggs into the water column after fertilisation.

The findings are critical towards protecting tropical marine diversity and may enable conservationists to better monitor the array of fish species in our reefs.
