During previous work Osa Peninsula (Bessesen Saborio-R. 2009), local residents described me population living Based information, marine sighting survey designed collect baseline distribution data for yellow during dry season 2010. These findings, which suggest separate behaviorally distinct xanthic (defined here as primarily yellow) colony, here. METHODS
