ResumenFrom the outside, the sea may appear as a homogeneous body of water. But technological advances have revealed it hides many living communities that dwell on the seafloor even at great depths. At shallow depths, many benthic communities are dominated by algae or sea plants, forming “forests” similar in structure and function to those we find on land. But at greater depths, where light is dim at best or does not reach, we can also find “sea forests”, though these are formed by animals such as gorgonians and other corals or sponges, for instance. These animal forests develop in such ways that they benefit from the currents and moving water masses which contain their food sources and upon which their sexual reproduction also depends. Their ecological importance is great: they act as places where many other species congregate, becoming sites of great biodiversity, as well as nurseries for larvae and juvenile individuals of many commercial species. These animal forests are still being studied extensively, despite extensive destruction by humankind’s extractive activities, as fishermen have long known since such locales have historically been rich in catches. Technology may help scientists to better visualize these marine forests so that the general public can more fully appreciate them and thus help preserve them and the marine ecosystem in general
