Reef Fish
Lionfish
Pterois volitans · Bony fish, family Scorpaenidae (scorpionfishes); the red lionfish, with the near-identical Pterois miles sharing the story
A lionfish hunting at dusk is theater: pectoral fins flared into banded fans, herding small fish into corners before an engulfing strike measured in milliseconds. Across its native Indo-Pacific and Red Sea range it is a modest, mostly solitary predator kept in balance by its ecosystem. In the western Atlantic it became something else: introduced off Florida in the 1980s, lionfish spread through the Caribbean, the Gulf of Mexico, and down to Brazil with no effective predators, eating juvenile reef fish at damaging rates. Many destinations now run sanctioned culls, and lionfish turn out to be excellent eating once the venomous spines are removed. Divers see them hovering under ledges and wrecks by day, often upside down against the ceiling, trusting their spines completely.
Waar en wanneer je er een kunt zien
"Resident" betekent dat je ze bij de meeste duiken op die bestemming tegenkomt; "seizoensgebonden" betekent betrouwbaar aanwezig in de vermelde maanden; al het andere is een bonus, geen garantie.

Ze begrijpen
Habitat: Reef ledges, wrecks, pilings, and lagoon patch reefs; in the invaded Atlantic it also thrives far deeper than most divers go.
Verspreidingsgebied: Native to the Indo-Pacific and (as Pterois miles) the Red Sea; invasive across the western Atlantic, Caribbean, and Gulf of Mexico since the 1980s–2000s, with Mediterranean spread underway.
Gedrag: Slow, confident, and mostly crepuscular; hovers under overhangs by day, often inverted, relying entirely on venomous spines for defense.
Dieet: Small fishes and crustaceans herded against the reef and engulfed whole.
Grootte: doorgaans rond 0.3 m; gedocumenteerd tot 0.47 m (total length; invasive Atlantic fish often grow larger than those in the native range).
Hoe je je ertegenover gedraagt
In the native range, observe like any scorpionfish. In the invaded Atlantic, leave removal to trained, locally sanctioned hunters and report sightings where destinations ask for them.
Behoud
Secure as a species; the conservation problem is the Atlantic invasion, managed by culling because eradication is no longer considered possible.
