California Lizardfish

California Lizardfish, Synodus lucioceps

The California Lizardfish, Synodus lucioceps, whose common Spanish name is Chile Lucio is a member of the Lizardfish or Synodontidae Family, known collectively as “Chiles” in Mexico.

The California Lizardfish have elongated (width 12-14% of standard length) tubular robust bodies with an overall mottled brown coloration, which is cream and gray dorsally and abruptly pale ventrally. They have a subtle row of approximately eight irregular dark blotches along their mid-flank. Their gill membranes and pelvic fins are yellowish; their adipose fin, caudal fin, and pectoral fins are dark; and their anal and dorsal fins are transparent with dark rays. Their head is wide and medium-sized (22-24% of standard length) and features a long pointed snout, large eyes, and a slightly oblique mouth. Their mouth is large and extends well past the eyes; it opens at the front and is equipped with many rows of fine pointed teeth. They have a straight lateral line. Their anal fin has a long base that is equal in length to their dorsal fin base; their caudal fin is forked; their dorsal fin is mid-body and originates closer to their adipose fin than their snout tip; their small adipose fin is above their anal fin; and their pelvic fins are large and found behind their pectoral fins. Their fins are spineless.

The California Lizardfish are found on the bottom (demersal) within and over sandy and muddy bottoms at depths between 5 and 750 feet. They reach a maximum length of 64 cm (25.2 inches). They are voracious ambush predators feeding primarily on small fish, krill, squid, and shrimp. They in turn are preyed on by sea lions. They have a limited distribution and are found along both coasts of Baja; they are absent from water adjacent to the mainland. They are a poorly studied species and very little is known about their behavioral patterns.

The California Lizardfish can be confused with the Iguana Lizardfish, Synodus sechurae (short pectoral fins, white spots along the lateral line), and the Lance Lizardfish, Synodus scituliceps (short head, uniform body coloration).

The California Lizardfish are viewed by local fishermen as a by-catch of no value. Furthermore, their small mouths require small hooks for success. They are strictly a “catch-and-release” that can become pests to recreational anglers.
