The longest tunnel in Passages of the Deep also represents the world’s largest environment – the Open Sea. There are no towering kelp forests or narrow rocky channels here… just water as far as the eye can see. Most of the species represented in this exhibit live in the upper strata of water, commonly referred to as the Sunlit Zone. This area is alive with four species of shark, huge bat rays and great schools of anchovy and mackerel. The sharks are particularly popular with Aquarium visitors and all our species are native to Oregon coastal waters, including our largest specimen, the Broadnose Sevengill Shark.
