The Canaries have two lizardfish, and between them they explain a whole category of unexpected bite: an angler working a small soft plastic over the sand beside a reef, expecting a bream, hooks something that looks like a reptile.
*Synodus saurus* is a long, round-bodied, brown-mottled fish with a big lizard-like head, a wide mouth full of fine needle teeth, and eyes set high and forward. It lies on clean sand, often part-buried, immediately beside structure, and launches upwards at anything of a size it can swallow. FishBase records it to 40 cm and 0.3 kg, over a depth range of 1 to 400 m but usually shallower than about 20 m.
Nine of them came to a light-tackle angler in a week around Puerto del Carmen, which puts it seventh in his tally and makes it a normal rather than a notable capture on that ground. The distribution runs Morocco to Cape Verde including the Azores and the Mediterranean, with a separate western Atlantic population from Bermuda and the Bahamas to the Leeward Islands.
It is separated from the diamond lizardfish, which shares the same sand, by pattern: this species carries a row of diffuse dark blotches or bars along the flank rather than the diamond lizardfish's more sharply defined dark rectangular saddles. The teeth on both are fine, numerous and worth respecting on a fish being unhooked.
Where Atlantic lizardfish is documented
Places where public sources describe this species as fished, with how it is fished and how strongly the evidence supports it. This is not a range map and it is not a recommendation — it is what has been written down about a fishery rather than a record of any individual catch, and being listed is never permission to fish.

What these strengths mean
- Recorded here
- At least one credible public account of this species being caught here. That is all it means.
Identification
No photograph of Atlantic lizardfish has passed identity review yet, so none is shown. FishingHQ publishes a species photograph only once somebody has confirmed the animal in it against the species record’s own diagnostic features.
- Scientific name
- Synodus saurus
- Family
- Synodontidae
- Water
- Saltwater
- Conservation status
- Least Concern
- Regions
- Western Europe, North Africa, West Africa, Mediterranean, Caribbean
- Long, round-sectioned, cigar-shaped body with a broad flattened lizard-like head and high-set forward eyes.
- A wide mouth carrying many fine, sharp, needle-like teeth, including on the tongue.
- Diffuse dark blotches or bars along the flank over a brown and cream ground.
- A small fleshy adipose fin on the back behind the dorsal, which most of the fish it shares ground with do not have.
- Taken lying on clean sand beside rock rather than over the rock itself — the ground it is on is half the identification.
Size
- Typical
- 15–25 cm
- Large
- 30 cm and over
Exceptional: FishBase records a maximum of 40 cm and 0.3 kg
Lifecycle and reproduction
Demersal over a depth range of 1 to 400 m but usually shallower than about 20 m, on clean sand and rubble adjacent to structure. Medium resilience. It is sedentary rather than ranging: a patch of sand beside a reef edge will hold one repeatedly.
Not documented on the FishBase record for this species, and left so. Synodontids generally release pelagic eggs; that is a family statement rather than a fact established about this fish.
Feeding and senses
A sit-and-wait ambush predator. It rests on or partly buried in sand and launches vertically at small fish and crustaceans passing above, taking them into a mouth built entirely for holding rather than cutting. Its capture on lures is a direct expression of that: a small paddletail worked over sand at its level is exactly the silhouette it is waiting for.
Vision, upwards, at short range in clear water. The strike comes from below, which is why a lure fished slightly too high catches lizardfish and a lure dragged along the bottom often does not.
Through the year
Resident year-round on the same ground rather than seasonal. It is sedentary to the point that a particular patch of sand beside a reef edge will hold a lizardfish repeatedly across a week, which is a genuinely useful thing to know: a mark that produced one is worth going back to rather than a mark that has been used up.
Distribution
Eastern Atlantic: Morocco to Cape Verde, including Azores and the Mediterranean. Western Atlantic: Bermuda and the Bahamas to the Lesser Antilles (Leeward Islands)
This is a biological range — where the species occurs, not a prediction that you will catch one. To browse the fishing geography FishingHQ holds, start at fishing places.
Why anglers care
A regular capture in Canary and Mediterranean light lure fishing over clean ground beside rock, and one of the reasons a soft plastic outfishes bait on that ground. Taken on small paddletails and grubs on jigheads and on drop-shot rigs. It is edible and little eaten, and its main significance to an angler is recognising what has just come up and keeping fingers out of it.
Handling and returning
The mouth is full of fine needle teeth pointing backwards, and they are what a hand meets when somebody reaches in to retrieve a swallowed jighead. Unhook with pliers, hold across the body behind the head, and cut the trace on a deeply hooked fish rather than working the hook out by hand.
Safety
Species that bite — Minor injury
The teeth are fine, numerous and backward-raked, so a finger put into the mouth is grazed going in and cut coming out. Not a serious injury, and a reliable one on a fish that has swallowed a lure.
What reduces it: Unhook with long-nosed pliers and never with fingers, grip across the body behind the head, and cut the trace on a fish hooked out of reach.

Diamond lizardfish
Synodus saurus carries diffuse dark blotches and is recorded as demersal; Synodus synodus carries sharply defined dark saddles, is often redder, and is recorded as reef-associated. The same observer took both in one week and counted them separately.

How it is caught
Reported, not established — 1 connection
Reported, but without independent support. Recorded because it is in circulation, not because it has been shown to hold.
Light rock fishing
Recorded nine times from the pier and the breakwater. It strikes upward from the bottom, so a small paddletail fished slightly above the sand is the presentation that produces it.

Inshore ground
Recorded as demersal from 1 to 400 m but usually shallower than about 20 m. It is a sand-lying ambush predator, so the clean inshore bottom beside hard ground is the habitat rather than the reef itself.
