How dangerous is lionfish venom?

What is lionfish venom made of?
The venom consists of a neuromuscular toxin that’s similar to cobra venom in toxicity. A lionfish delivers the venom when its spine penetrates the skin of predators, or in some cases, an unsuspecting human.

Can lionfish defend themselves?
Lionfish spines convey venom to animals that touch them, creating an effective defense against the vast majority of predatory ocean animals. Their venom is a leading reason for their success as an invasive species since new ecosystems have few natural predators that are adapted to get around this mechanism.
Are sharks immune to lionfish venom?
Reef sharks are thought to be one of a few animals that can choke down a lionfish.

Small and manageable as a pet, Dendrochirus brachypterus has bags of personality for a lionfish — although it can still pack a punch and tank mates should be chosen with caution!
What is the sanctuary doing to help the lionfish problem?
The sanctuary research team works closely with other government and non-government agencies across the Gulf of Mexico and Caribbean to better understand the invasive lionfish problem and work toward solutions. Lionfish dissections give us data that is helpful in understanding the lionfish problem. Photo: FGBNMS/Drinnen
