Synodus saurus, commonly known as the Atlantic Lizardfish, is a demersal marine fish belonging to the family Synodontidae. It is characterized by its elongated, cylindrical body, large mouth, and cryptic coloration, which allows it to blend seamlessly with sandy or rocky substrates. This species is a voracious ambush predator, spending much of its time partially buried in the sediment, waiting for unsuspecting prey.
Caratteristiche fisiche
- Forma del corpo
- elongated
- Colorazione
- Dorsal surface typically sandy brown to grayish, often with irregular darker blotches or saddles that aid in camouflage. The ventral side is lighter, whitish. A series of indistinct dark spots or bars may be present along the lateral line. The fins are generally translucent with some dusky markings.

- Elongated, cylindrical body, tapering towards the tail., Large, broad head with a prominent, wide mouth extending well past the eye., Numerous sharp, needle-like teeth on both jaws, the tongue, and the roof of the mouth., Adipose fin present between the dorsal and caudal fins., Eyes located dorsally on the head, allowing for upward vision while buried.
- Pinna dorsale
- Single dorsal fin, typically with 10-13 soft rays. An adipose fin is present posterior to the dorsal fin.
- Pinna caudale
- Forked caudal fin.
- Pinna pettorale
- Relatively small, positioned low on the body, with 11-13 rays.
- Pinne distintive
- Pelvic fins are large, located anterior to the pectoral fins, and have 8 rays, with the inner rays being longer than the outer ones. This allows them to act as props when resting on the substrate.
Consigli per l'identificazione
Body Shape and Coloration
Look for the elongated, lizard-like body and cryptic sandy-brown coloration with irregular darker blotches. This helps it blend with the seafloor.
Head and Mouth
Note the large, flattened head and the very wide mouth extending beyond the eye, armed with numerous sharp teeth. The eyes are positioned dorsally.
Adipose Fin
The presence of a small, fleshy adipose fin between the dorsal and caudal fins is a key characteristic of the family Synodontidae.
Pelvic Fins
Observe the large pelvic fins located anterior to the pectoral fins, with the inner rays longer than the outer ones, used for propping itself on the substrate.
Habitat
- Tipo di acqua
- saltwater
- Profondità
- Typically found from the surface down to about 400 meters (1,300 feet), but most commonly observed in shallower coastal waters, usually less than 100 meters.
- Ambiente
- Demersal, inhabiting sandy or muddy bottoms, seagrass beds, and rocky reefs. They prefer areas with good cover for ambush predation.
- Areale geografico
- Widespread in the Atlantic Ocean, including the Mediterranean Sea, the eastern Atlantic from Portugal to Angola, and the western Atlantic from Bermuda and North Carolina south to Brazil, including the Gulf of Mexico and the Caribbean Sea.

Fatti chiave
Ambush Predatorbehavior
Synodus saurus is a classic ambush predator, often burying itself in sand or mud with only its eyes protruding, waiting for unsuspecting prey to swim by.
Lizard-like Appearanceinteresting
Its common name, 'Lizardfish,' comes from its elongated body and flattened head, which give it a reptilian appearance.
Voracious Appetitebehavior
Despite its relatively small size, the Atlantic Lizardfish is a highly efficient and voracious predator, consuming a wide variety of smaller fish and invertebrates.
Hermaphroditismamazing
Like many other lizardfish species, Synodus saurus is a synchronous hermaphrodite, meaning individuals possess both male and female reproductive organs simultaneously.
Informazioni di sicurezza
Maneggiare con cura- Livello di sicurezza: caution
- Velenoso: No
- Commestibilità: edible
- Note sul maneggio: While not venomous, Synodus saurus possesses numerous sharp, needle-like teeth. Care should be taken when handling to avoid painful bites. Anglers should use pliers or a dehooker to remove hooks. They are known to thrash vigorously when caught, so caution is advised.
Specie simili
Greater Lizardfish
Synodus synodus
Synodus synodus typically has more distinct dark blotches or bars along its sides, often forming a more defined pattern. Its head is generally less flattened, and the mouth may not extend as far past the eye as in S. saurus. The number of lateral line scales and fin rays can also differ upon close examination.
Red Lizardfish
Synodus erythrinus
Synodus erythrinus often exhibits a reddish or pinkish hue, especially when alive, which is distinct from the sandy-brown of S. saurus. Its body tends to be more slender, and its markings are usually less pronounced or absent.
Shortfin Lizardfish
Synodus intermedius
Synodus intermedius generally has a more robust body and a shorter, broader snout. Its coloration can be similar, but often features more prominent dark spots or bars. Fin ray counts and scale counts are important for definitive identification.
