Jelly have no brains, no heart, and no blood, so it’s pretty incredible to think that they have survived more than 500 million years. More than 100 species of jellyfish have been recorded along the Great Barrier Reef in Australia. Jellyfish are a favorite food for the Reef’s marine turtles and often protect small fish that hide in their tentacles for protection.
Facts about Jellyfish:
• Jellyfish are not actually fish, they are gelatinous zooplankton.
• Their bodies are made up of 98% water.
• Some jellyfish can see. For instance, a boxed jellyfish has 24 ‘eyes’ but only two of them are capable of seeing in color. It is also believed that this is one of the few creatures in the world to have a full 360-degree view of its environment.
• A group of jellyfish are usually called a bloom, swarm, or sometimes a ‘smack.’
• NASA first started sending jellyfish to space on board with the Columbia space shuttle in the earl 1990s to test how they might be along in a zero-gravity environment.
In order to help with jellyfish populations, Slacktyde gives 10% of sales to Great Barrier Reef Foundation.
