The animals you’ll get to see and possibly touch in the touch pools are invertebrates—animals without backbones. The most familiar marine invertebrates include crabs, sea anemones, jellies, sea stars, sea urchins, sea cucumbers and shrimps. Even the octopus, one of the most popular animals at the Aquarium, is an invertebrate. You can find marine invertebrates in almost every marine habitat. Some marine invertebrates, including tube worms, live on the ocean bottom near vents that expel sulphide-rich water heated to 400°C.
