Dinner Time On the Seafloor Below 12,00 Feet with Sea Cucumbers and Sea Spiders

While exploring the slopes of unnamed seamounts near Johnston Atoll we encountered some rare and exciting wildlife. Some of the stars of this compilation video are the semi-transparent sea cucumbers with their digestive tracts on full view to our control van team. Enjoy this glimpse of the sea floor that also includes a rather large sea spider predating a bamboo coral.

Finding a meal at the bottom of the ocean is never easy since without sunlight, photosynthesis is impossible. Instead, most animals (like these sea cucumbers) that reside this far down consume detritus from the surface waters as their primary source of food. Others are predators, like the sea spider, that will make a meal of the filter-feeders, thus creating a unique deep ocean food web.
