Species Overview
Perca-gigante
The barramundi is a large, catadromous predator native to the Indo-West Pacific. It is a protandrous hermaphrodite, beginning life as male and transitioning to female after several years. Highly prized in both sport fishing and aquaculture.
Great Hammerhead Shark
The great hammerhead is the largest of the nine hammerhead shark species. Its distinctive cephalofoil (hammer-shaped head) houses an array of electroreceptors that allow it to detect stingrays buried beneath the sand.
