Jellyfish inhabit all oceans around the world from the warm Caribbean Sea to the frozen Arctic. Jellyfish are one of the most captivating creatures to watch with their undulating body movements and flowing tentacles. These fascinating animals have no brains, blood, or hearts, making them beautiful but straightforward creatures. In fact, jellyfish consist of only 5% solid matter and 95% water. It’s no wonder they move like they are one with the sea. Don’t let their elegance fool you; however, all jellyfish have venomous tentacles, some that humans cannot feel at all, and some that can pack a good sting. It is important to know which jellyfish species are common in the areas you will be diving as some, like the box jelly, can be life-threatening. Make sure you wear proper exposure protection at all times to protect against potential jellyfish stings.
Diving with jellyfish is an exciting experience but always use caution and keep a reasonable distance. Like most marine animals, the colder the water, the larger the species get, and jellyfish are no exception. Avid divers plan dive trips to the more frigid waters of the Arctic to swim with the world’s most giant jellyfish, the Lion’s mane. If you like to live on the adventurous side, you can join the many divers who travel to Australia to dive with one of the most beautiful jellyfish in the world, but also the most toxic, the box jelly, also known as the sea wasp. No matter where you dive in the world, you are sure to see at least one jellyfish along the way. Click here to learn more about specific types of jellyfish and where you can see them.
