In this paper report a new size record for this species is reported, based on a single specimen captured in Bahía Culebra, on the Northern Pacific coast of Costa Rica, in September 2020, as well morphometric and meristic data obtained from museum specimens, complementing previous descriptions. We also provide length-weight data generated from fresh and preserved specimens as a basis for calculating/estimating biomass and condition, with direct implications for the establishment of management measures, as well as conservation activities at both local and regional scales. <em>Haemulon sexfasciatum</em> has isometric growth, determined by the following equation: Weight = 0.0227 * Standard Length<sup>3.0400</sup> (r<sup>2</sup> = 0.99), with a maximum standard length of around 60 cm and a maximum total length of about 71 cm.</p> Arturo Angulo Federico Hampl ##submission.copyrightStatement## 2021-07-27 2021-07-27 9 21 10.15359/revmar.13-2.1 Predation of Gecarcinus quadratus (Decapoda: Gecarcinidae) by Aramides cajaneus (Gruiformes: Rallidae) in Costa Rica https://www.revistas.una.ac.cr/index.php/revmar/article/view/16058 <p><em>Gecarcinus quadratus</em> is a land crab preyed upon by some species, but there is little information about the genera and species of these predators. This scientific note presents the first record of <em>Aramides cajaneus</em> preying upon <em>G. quadratus</em>. This observation occurred during daylight in May 2021 in Costa Rica, and contributes to the knowledge about the natural history, behavior and ecology of these species.</p> Sergio Villegas-Retana Jorge Picado-Masís ##submission.copyrightStatement## 2021-07-27 2021-07-27 23 26 10.15359/revmar.13-2.2
