    • Abstract:
      En diciembre de 2021 se desarrolló la primera expedición a los montes submarinos de las dorsales de Malpelo y de Yuruparí. En total se exploraron ocho montes submarinos por medio de BRUVS (Baited Remote Underwater Video Systems). Se desplegaron 48 BRUVS, registrando cinco especies pelágicas (Sphyrna lewini, Mobula birostris, Pteroplatytrygon violácea, Kajikia audax y Istiophorus platypterus), donde Pteroplatytrygon violácea constituyó un nuevo registro para la región. En todas las zonas se registraron especies pelágicas, aunque los tiburones se asociaron exclusivamente a los montes al oeste de las dorsales, en especial al monte conocido como Bajo Navegador, el más somero de la región. Este trabajo es un primer paso para orientar las siguientes exploraciones de estos ecosistemas. [ABSTRACT FROM AUTHOR]
    • Abstract:
      In December 2021, we conducted the first expedition to the seamounts of the Malpelo and Yuruparí ridges. Eight seamounts were explored using Baited Remote Underwater Video Systems (BRUVS). A total of 48 BRUVS were deployed, registering five pelagic species (Sphyrna lewini, Mobula birostris, Pteroplatytrygon violacea, Kajikia audax and Istiophorus platypterus) where Pteroplatytrygon violacea constituted a new record for the region. Pelagic species were recorded in all seamounts, although sharks were exclusively associated with the seamounts to the west of the ridges, especially in the area known as Bajo Navegador, the shallowest seamount in the region. This work is a first step to guide the following explorations of these ecosystems. [ABSTRACT FROM AUTHOR]
