- Baldchin Gropers are endemic to Western Australia, specifically distributed between Shark Bay and Recherche Archipelago. This limited distribution contributes to their vulnerability.
- They have a robust, elongated body, and their heads are pointed, with large mouths and lips. Baldchin Gropers are known for their noticeable “bald” chin without scales, and distinctive markings and coloration. They exhibit a wide range of colours, from pink, purple, to green, with two dark vertical bars across their body.
- They are carnivores that primarily feed on molluscs, crustaceans, echinoderms, and small fish.
- Baldchin Gropers can show territorial aggressive behaviour, especially males towards other males. They might use a head-down posture, rapid swimming, or even physical attacks to defend their territory.
- Juvenile fish are often found in shallow seagrass habitats. As they grow older, they move to deeper reef environments. The availability of these different habitats at various life stages is crucial for their survival and growth.
- They are protogynous hermaphrodites, meaning they first mature as females and have the ability to change sex to male later in life. Spawning usually occurs between September and November, with eggs and larvae being pelagic.
- They are a long lived species with a estimated lifespan up to 20 years or more in the wild.
