From the Indo-Pacific to Mexico: establishment of the Longfin Batfish, Platax teira (Forsskål, 1775) (Acanthuriformes, Ephippidae), in the Tropical Eastern Pacific

We report 100 individuals of the Longfin Batfish, Platax teira (Forsskål, 1775), from the Mexican Pacific. Records include first reports from the Revillagigedo Islands and Michoacán, as well as additional sightings from Baja California Sur, Jalisco, Colima, Guerrero, and Oaxaca. Individuals included juveniles, subadults, and adults documented through diving, snorkeling, and one incidental fishery capture. The marked increase in records, including multiple individuals at different life stages, indicates that P. teira is becoming increasingly recurrent in the Tropical Eastern Pacific and suggests continued geographic spread and possible early population establishment.
