  • Descrição: Halichoeres socialis Randall & Lobel, 2003, is the only wrasse species (Teleostei: Labridae), with a distribution confined within the Western Caribbean’s Bay of Honduras region and is most concentrated in the Meso-American Barrier Reef (MABR) lagoon of Belize. This study examined the early life history of H. socialis to gain insight into its natural history and to assess if any pattern in otolith microstructure could be linked to its biogeography. The sagittal otoliths from 67 individuals (ranging 9.8–43.4 mm SL) were analyzed to determine the daily age and increment profile. Results indicate that (1) H. socialis displays a typical “settlement mark”; (2) the pelagic larval duration (PLD) ranged from 22 to 32 (mean = 27, n  = 59) days, which was similar to its congeners; and (3) the juvenile growth rate is 0.7 mm/d, which was faster than most congeners. The biogeography of H. socialis is not explained by its PLD. Alternatively, it is possible that larval behaviors (vertical migration and/or schooling) play a key factor in the distribution of H. socialis larvae.
