Scorpaenidae

Scorpaenidae is a family of marine ray-finned fishes that includes scorpionfishes and lionfishes. Many species have venomous fin spines.

Scorpaeniformes: A taxonomic order of ray-finned fishes that includes scorpionfishes and related groups. Scorpaenidae belongs to this broader grouping, though classifications of the order vary.
Lionfish envenomation: Poisoning caused when a lionfish spine punctures skin and delivers venom. It is a well-known example of the defensive injury caused by scorpaenid spines.
Lionfish invasion in the western Atlantic: The establishment and spread of Indo-Pacific lionfish in western Atlantic and Caribbean waters. This invasion has made one scorpaenid group a major target of ecological management.
Red lionfish: A venomous Indo-Pacific lionfish species, Pterois volitans, established as an invasive predator in the Atlantic. It is among the most recognizable scorpaenids and a prominent invasive species.
Synanceiidae: A fish family containing stonefishes, classified separately from Scorpaenidae in some taxonomic systems. Stonefish classification has shifted, so its family placement can differ among references.
Ray-finned fish: A fish whose fins are supported by slender bony or cartilaginous rays. Scorpaenidae is one family within this vast class of fishes.
Ambush predation: A hunting strategy in which a predator waits concealed before rapidly capturing prey. Many scorpionfishes rely on camouflage and sudden strikes to catch smaller animals.
Lionfish culling: The targeted capture and removal of invasive lionfish from marine ecosystems. Divers and fisheries remove lionfish to reduce their predation on native reef animals.
Common lionfish: A venomous Indo-Pacific lionfish species, Pterois miles, closely related to the red lionfish. It is another lionfish involved in the western Atlantic invasion.
Trachinidae: A family of venomous marine fishes commonly called weeverfishes. Weeverfishes also have venomous spines but are not members of Scorpaenidae.
