Pterois antennata
Pterois is a genus of venomous marine fish found mostly in the Indo-Pacific, known collectively as the lionfish. Pterois is characterized by red, white and black stripes, showy pectoral fins and venomous spiky tentacles.[1][2] Pterois are classified into fifteen different species, but Pterois radiata, Pterois volitans and Pterois miles are the most commonly studied. Pterois are popular aquarium fish and are readily utilized in the culinary world
Lionfish are known for their venomous tentacles; a feature that is uncommon among marine fish in the East Coast coral reefs. The potency of their venom makes them excellent predators and dangerous to fishermen and divers. [2] Pterois venom produced negative inotropic and chronotropic effects when tested in both frog and clam hearts [7] and has a depressing effect on rabbit blood pressure.[8] These results are thought to be due to nitric oxide release. [6] In humans, Pterois venom can cause systemic effects such as vomiting, fever and sweating and has been lethal in a few cases.
