Western Red Scorpionfish

Scorpaena sumptuosa

The Western Red Scorpionfish, known scientifically as Scorpaena sumptuosa, is a venomous marine fish endemic to Western Australia. Divers can recognize this species by its deep-bodied form and distinctive mottled red to brown coloration, featuring two wide vertical bands that extend onto its fins. It is distinguished from other scorpionfish by its maxillary ridge, a very deep occipital pit, and thickened skin with numerous pores near the lateral line. The body is adorned with tentacles that help in camouflage, and its eyes are positioned high on the head. This species can grow up to 40 cm in length. The Western Red Scorpionfish inhabits coastal reefs from Shark Bay to Albany, Western Australia, typically found at depths down to 60 meters. It is an ambush predator, lying motionless among corals and algae, waiting for unsuspecting prey to come within range. It uses its prehensile mouth to suck in prey, and its venomous spines serve as a defense mechanism against potential threats. It is not currently evaluated by the IUCN, and divers should be cautious of its venomous spines when encountered underwater.
