About the dusky grouper
- The grouper is named after its gill cover with the jagged edge.
- Especially interesting: It is a protogynous hermaphrodite. This means that the fish is originally female. Starting from a body length between 40 and 80 centimeters it changes its sex and becomes a male!
- The grouper can live up to 50 years and is considered today, due to commercial fishing, as highly endangered.
