Description: The deep ocean (> 200 meters depth, seaward of the continental shelf break), is the largest environment on Earth, and is also home to some of the most fascinating living creatures. The fishes that evolved in this environment developed unique morphological and physiological adaptations to live under extreme conditions of high pressure, low temperature and the absence of light. Despite the great diversity of forms and species, the knowledge concerning the biodiversity and evolution of deep-sea fishes remains relatively poor. Over the past years, the increase in the number of scientific expeditions using new technologies to sample and observe the deep allowed the exploration of difficult-to-access areas, including some of the world’s deepest trenches. These, in concert with research using both traditional and molecular techniques, illuminates new views on the evolution, use of habitats, and ecology of deep-sea fishes. The aim of this session is to stimulate discussion on different topics of deep-sea fishes: behavior, ecology, evolution, morphology, biogeography, and systematics.
Expected Audience: We expect to put together a broad range of researches interested on different aspects of deep-sea fishes. In this way, the participants will be able to show their results to a larger audience, discuss new goals, and to stimulate further cooperation within the Indo-Pacific and other areas.
