Mottled and motionless on sand, red lizardfish are a common find around Tenerife and Gran Canaria in warm 23-28C water year-round.
Long, slender body shaped almost like a torpedo, propped up on its pelvic fins as it rests on sand or rubble. Skin is mottled reddish-brown to olive with a pattern of blotches and bars that breaks up its outline against the seabed. A pointed, reptilian snout and large upward-angled mouth give it its name, and it typically holds dead still, only its eyes tracking movement.
Spends most of a dive parked motionless on sand, rubble or low reef, propped up on its pelvic fins like a tripod and blending into the substrate. It relies on that stillness and camouflage rather than fleeing, letting divers get close for a look before darting off in a short, fast lunge if it does bolt, usually while ambushing passing prey rather than reacting to you.
That sit-and-wait posture isn't resting: lizardfish are ambush predators that stay still to let small fish and shrimp wander within striking range, then snap forward in a burst too quick to see clearly.
No clear seasonal pattern shows up in the data, and with a comfort range of roughly 23 to 28C it turns up on these reefs year-round rather than on a migration schedule.
Most reliably logged across the Canary Islands, especially Tenerife, Gran Canaria, Lanzarote, Fuerteventura and El Hierro, with strong numbers also out of Madeira and Cape Verde's São Vicente. Further sightings turn up in Crete and mainland Greece, along the Turkish coast, in Saint Vincent and the Grenadines, and off Senegal and Italy.
Mapping where Red Lizardfish is logged…
The Canary Islands are the standout destination, particularly Tenerife, Gran Canaria, Lanzarote, Fuerteventura and El Hierro. They're also a solid find in Madeira, Cape Verde's São Vicente, Crete, and along the Turkish coast.
There's no strong seasonal signal in sightings, and their comfortable water temperature range of 22.8 to 28C means they're around on these reefs throughout the year.
Look for a slender, snake-like fish around 30cm long, propped motionless on sand or rubble on its pelvic fins. Its mottled reddish-brown blotches and long, pointed snout with a big mouth are the giveaways.
They typically reach around 30cm in length, a slim, elongated body built for lying flat and unnoticed on the seabed.
No, they pose no threat to divers. They ignore passing swimmers almost entirely and only move fast when ambushing small prey.
They hunt by doing almost nothing: propped on their pelvic fins and camouflaged against the seabed, they wait for prey to wander close before striking in a burst of speed that's over almost before you register it.
