Jellyfish & Cnidarians

Moon Jellyfish

Featured Animal: Moon Jellyfish

Moon Jellyfish can be found in the coastal Pacific seas all around the Ring of Fire. While they have four feeding tentacles, tens of thousands of stinging cells and five stomachs, they have no bones, nervous system, brain or muscles, are 97% water, and nobody knows how they move!

The hundreds of Moon Jellyfish in the Ring of Fire: World of the Octopus exhibit will be born and raised at the aquarium by our animal care experts!

Cnidarians are invertebrates with stinging cells called nematocysts. Included in the cnidarian group are anemones, corals, and jellyfish

A nematocyst is a cell that contains a coiled-up venomous barb. When touched, the barb is discharged into the skin of the prey and the venom is released.

Although a nematocyst is microscopic, when thousands of these are discharged into the skin, their effect can be dangerous or even deadly. Some of the most deadly animals in the world are the box jellyfish.


Ring of Fire: World of the Octopus

Ring of Fire is an immersive exhibit that will highlight the mysterious creatures that make their home along The Ring of Fire where towering volcanoes and deep ocean trenches line the Pacific Ocean rim.

Crabs & Arthropods

Arthropods are invertebrates with an exoskeleton, a hard and protective outer shell made of chitin. They also have appendages that are jointed and their bodies are segmented.

The term “echinoderm” means “spiny skinned” and is a very appropriate name for invertebrates in this group. Sand dollars, sea cucumbers, sea stars and sea urchins are all echinoderms.
