Indian Lionfish

Pterois miles

Indian lionfish (Pterois miles) is a venomous reef-associated predator native to the western Indian Ocean and invasive in parts of the Mediterranean. It lurks by day and ambushes small fishes and crustaceans at dusk and night.

Identification points

Tall, separate fan-like pectoral fins with long free rays
Distinctive red-brown and white zebra striping over the body and head
Long venomous dorsal spines and a head with fleshy tentacles above the eyes

Habitat

Coral and rocky reefs, drop-offs, lagoon edges, wrecks, jetties, and other structure from shallow water to around 50 m; often shelters in crevices by day and hunts over adjacent open bottom at night.

Bait notes

Small live baitfish, shrimp pieces, and cut fish can take them; small soft plastics and jigged minnows also work. In invaded areas they are often readily caught on very small offerings near reef structure.

Behavior

A slow, deliberate ambush predator that fans its pectoral fins to corner prey, then strikes quickly. It is largely nocturnal, territorial around cover, and will eat small fish and shrimp-sized crustaceans.

Caution

Highly venomous spines can cause severe pain and swelling; handle only with puncture-resistant tools and never by hand. If keeping one, cut spines carefully before transport; seek medical care for punctures, and follow local rules where it may be invasive or targeted for removal.

Fishing notes

Fish close to reef, wreck, or dock structure with light tackle and short pauses. Night fishing can be productive; use a hook/landing tool and avoid hand contact because the dorsal, anal, and pelvic spines are venomous.
