Abstract
This study presents new larval records of daggertooth fish Anotopterus pharao (Aulopiformes: Anotopteridae) in the southwestern Atlantic and explores its global distribution patterns. This species is extensively distributed in oceans, with concentrations in subtropical, temperate and polar regions. We found new records at depths between 550 and 1100 m, associated with Antarctic Intermediate Water. We collected eight larvae at different developmental stages: preflexion (n = 4), flexion (n = 3) and postflexion (n = 1). The presence of preflexion larvae suggests reproduction in southeastern Brazil. Additionally, their occurrence at great depths in lower latitude may indicate potential strategies such as latitudinal migration for reproduction and vertical migration to avoid thermal stress.
期刊介绍：
The Journal of Fish Biology is a leading international journal for scientists engaged in all aspects of fishes and fisheries research, both fresh water and marine. The journal publishes high-quality papers relevant to the central theme of fish biology and aims to bring together under one cover an overall picture of the research in progress and to provide international communication among researchers in many disciplines with a common interest in the biology of fish.
