Deep Sea Spongetopia on Explorer Seamount

Welcome to Spongetopia! During the last dive of the Northeast Pacific Seamounts Expedition, the team aboard Nautilus made a startling discovery while surveying Explorer Seamount, 250km offshore Vancouver Island, Canada. An otherworldly seascape greeted ROV Hercules, with thriving sponge gardens dotting the slopes of this underwater mountain. Spiraling from the seafloor, trumpet-shaped bugle sponges and vase-like boot sponges provide rich habitat for smaller animals, with some of these intricately-built glass sponges rising over a meter tall!
