New photographic records of eight marine fishes from the Galápagos Islands, including three first records for the Eastern Tropical Pacific

Abstract

We provide photographic evidence for eight fish species from five families, not previously seen within the Galápagos Marine Reserve. Four species are native to the Central Tropical Pacific and likely arrived during recent El Niño phenomena: Acanthurus leucocheilus Herre, 1927, Acanthurus olivaceus Bloch & Schneider, 1801, Naso hexacanthus (Bleeker, 1855), and Chaetodon punctatofasciatus Cuvier, 1831. One is a pantropical species: Kyphosus sectatrix (Linnaeus, 1758). The remaining species likely originated within the Eastern Tropical Pacific: Ctenochaetus marginatus (Valenciennes, 1835), Halichoeres malpelo Allen & Robertson, 1992, and Gymnothorax porphyreus (Guichenot, 1848).
