Ocean explorers sometimes encounter creatures that simply don’t appear to belong on this planet. We continually learn about ocean wildlife, yet extraordinary appearances, outlandish life cycles and bizarre behavior still strike us as “alien”.

Jellies epitomize this “alien” phenomenon. They look like umbrellas, can be bigger than a human, or smaller than a tack and have stinging tentacles. Yet they are poor swimmers and subject to the whims of ocean currents, making them one of the largest type of plankton.

Travel to our Planet Jellies gallery – one of the largest of its kind in the world – and learn more about the four species of jellies, beautifully exhibited in backlit kreisel tanks and colour-changing displays.



• Planet Jellies is home to one of the largest kreisel tanks in the world!

What is a kreisel tank?

A kreisel tank is a special tank designed specifically to keep jellyfish. Unlike standard aquarium exhibits, a kreisel tank is a horizontal cylinder, created to eliminate elements in a regular tank that could compromise the life of a jellyfish – such as corners and bubbles. Believe it or not, jellyfish are such poor swimmers they can easily become trapped in corners and bubbles can tear through their bells.

• Our Life Cycles Exhibit showcases moon jellies at all stages of their life, from polyp to medusa.

• Look up! Planet Jellies has a ceiling exhibit, allowing guest another angle to view these mesmerizing creatures!

• How does one take care of a jellyfish? Find out that and more with our blog post “Jellyfish 101”!
