Mexican Blenny, Paraclinus mexicanus
The Mexican Blenny, Paraclinus mexicanus, whose common Spanish name is trambollito mexicano, is a species in the family Labrisomidae, the Labrisomid Blennies, known as trambollos in Mexico. Globally, there are twenty three species in the genus Paraclinus, of which thirteen are found in Mexican waters, five in the Atlantic and eight in the Pacific.
The Mexican Blennies have elongated bodies with a uniform depth throughout that taper gradually at the rear into the tail. They are heavily mottled in green and brown with six or seven diffuse bars on the sides that are more prominent adjacent to and extend into the dorsal fin. They have a prominent white edged oblique dark bar below the eye and a black ocellated spot on the rear of the dorsal fin. The anal and dorsal fins have thick dark bars and the caudal fin is spotted. Their head has a bluntly pointed blunt snout, large eyes and lips and a branched cirrus on the nostril and over each eye. Their mouth is large and opens at the front. Their anal fin has two spines and 17 to 20 rays; their caudal fin is square; and their dorsal fin has 17 to 21 spines and 0 to 2 rays with a deep notch in between the third and fourth spines. They are covered with small smooth scales.
The Mexican Blenny is a shallow water coastal species found within weed covered rocky shores that is active diurnally (day time) as a highly territorial predator that feeds mostly on benthic crustaceans including small crabs. They reach a maximum length of 6.0 cm (2.4 inches) and they are found at depths up to 35 feet. Reproduction is oviparous with the females depositing eggs in protected areas. Very little is known about their behavioral patterns. In Mexican waters the Mexican Blenny is found in the lower half of the Sea of Cortez and along the coast of the mainland north of Acapulco; they are absent from along the Pacific Coast of Baja.
The Mexican Blenny is not easily confused with any other blenny due to their unique coloration pattern.
Due to the size and rarity that are of limited interest to most.
