Blue Planet Aquarium in Cheshire Oaks, Ellesmere Port, offers cage-free Shark Dive experiences in its Ocean display tank alongside 12-foot Sand Tiger Sharks, Nurse Sharks, Blacktip Sharks and rays. The Adult Shark Dive is run as a Discover Scuba Dive (no diving qualification required or issued, though the dive can be logged towards a future certification) with full tuition, briefing and equipment provided; a supervised Junior Shark Dive for ages 8-15 takes place in the aquarium's reef tank. Blue Planet Aquarium does not offer diver training courses.
