Introduction 

Jellyfish may be found everywhere on the earth, from the surface to the deep oceans. Scyphozoans (sometimes known as “real jellyfish”) are only found in the sea, however other hydrozoans with similar appearances can be found in freshwater. Jellyfish of various sizes and colors may be found in coastal areas all over the world.

 Most species’ medusae develop quickly, mature in a few months, and perish soon after reproducing, while the polyp stage, which is linked to the seafloor, may survive much longer. Jellyfish are the oldest multi-organ animal group, having existed for at least 500 million years, and probably 700 million years or more.

In certain civilizations, jellyfish are consumed by humans. In certain Asian nations, species of the Rhizostomae order are pressed and salted to eliminate excess water and are regarded a delicacy. They are a “ideal meal,” according to Australian experts, since they are sustainable, protein-rich, and low in food energy.

They’re also employed in science, where the green fluorescent protein that causes bioluminescence in certain species has been repurposed to serve as a luminous marker for genes put into other cells or creatures.

Jellyfish stinging cells, which are employed to subdue their food, can harm people. Thousands of swimmers are stung every year across the world, with symptoms ranging from slight pain to catastrophic damage or even death. Jellyfish may create massive swarms when conditions are favorable, causing damage to fishing gear by overflowing fishing nets and occasionally obstructing the cooling systems of power and desalination facilities that draw their water from the sea.

They’re survival masters

Jellyfish are one of the most common water creatures. According to recent studies, there are around 38 million tonnes of them simply in the epipelagic, or above 200 meters of the ocean. Furthermore, they have colonized the bulk of marine ecosystems, including the deep sea, and are found in all oceans.

One of the reasons they’re so popular is that, contrary to popular belief, having a body made of jelly is a pretty effective approach. Gelatinous bodies have developed three times independently and have lived for at least 500 million years, surviving all five major extinction events that wiped off 99 percent of all life on Earth.

Jellyfish can be found in all ocean waters.

As the beach season begins, stories of jellyfish sightings and stings are started surfacing. Jellyfish may be found all over the world in any sort of ocean water since they just follow the ocean currents. They can live in either warm tropical or chilly Arctic water. They’ve been discovered at the ocean’s deepest depths as well as near the surface.

To begin with, jellyfish aren’t choosy. They can be found in seas all over the world, at the surface, deep beneath the sea, in warm water, cold water, and even freshwater, according to some species of hydrozoa.

When you get up close and personal with a jellyfish as it flows through the water column, you can fully appreciate its intricate but simple beauty. While some jellyfish have a strong sting, many jellyfish species (and their near relatives) are either non-stinging or essentially innocuous to humans. 

Here are four great spots across the world recognized for fantastic possibilities to dive with jellyfish, ranging from chilly to warm seas.

Prince William Sound, Alaska

Thousands of moon jellyfish congregate in the calm waters of Port Fidalgo in Prince William Sound every summer near Alaska’s coast. Jellyfish blooms typically extend hundreds of feet below the surface. Divers will be able to observe blue-tinted moon jellyfish as far as the eye can see, with no fear of getting stung, thanks to the exceptional water clarity compared to many of the surrounding places. You could catch a glimpse of a purple moon jellyfish or a bigger, predatory lion’s mane jellyfish on the fringes of the bloom if you’re lucky.

Jellyfish Lake, Palau

One of the most well-known jellyfish populations in the world may be found on Palau’s Eil Malk Island. This 12,000-year-old saltwater lake, known as ‘Jellyfish Lake,’ is home to hundreds of thousands of golden jellyfish that travel horizontally across the lake every day. This lovely creature has evolved to no longer sting, instead relying on symbiotic algae that dwell in their tissues for energy (similar to corals). Keep in mind that scuba diving is not permitted in the lake, so jellyfish fans will have to stay on the surface.

White Sea, Russia

Divers who go beyond the Arctic Circle and dive beneath the surface of the White Sea in Russia are nearly assured to see a variety of jellyfish species (and their close relatives). Every season of the year offers possibilities to dive with jellies, whether the water surface is liquid or solid (ice). On a long drift dive in the summer, see moon jellyfish and lion’s mane jellyfish. Meet various complicated and gorgeous species of hydrozoans (near jellyfish cousins) as they pulse smoothly through the water in the autumn, winter, and spring. Have your macro lens handy all year to see a variety of stalked jellies (small, complex jellyfish cousins that rest ‘upside down’) and a plethora of enormous comb jellies.

Tojoman Lagoon, Philippines

The lovely Tojoman Lagoon may be found in the Philippines’ Bucas Grande Islands. Visitors come from all over the world to see this jellyfish sanctuary and its large population of non-stinging jellyfish. They softly plunge in and are mesmerized by the tranquil beauty of the underwater habitat. Throughout the year, millions of spotted jellyfish with lovely small white spots may be seen here, but the ideal time to visit is during the hot summer months.

Jellyfish and its near cousins may be found in all oceans and come in a variety of forms, sizes, and colors. You must have a safe marine visit and avoid jellyfish stings whether you visit these spectacular jellyfish diving destinations or discover your own.

Safe sea product

Most jellyfish, sea nettles, sea lice, and coral have stinging mechanisms that can be protected with Safe Sea Sunscreen with Jellyfish Sting Protection. It has specific chemicals that prevent the stinging process from taking place, keeping you safe. Jellyfish and other marine stingers are becoming increasingly common both locally and internationally, but Safe Sea can help you avoid any unpleasant surprises! Safe Sea is Marine Friendly certified and has the “Friends of the Sea” symbol.

Conclusion

Jellyfish have been there since the beginning of time, populating all of the world’s waters and evolving into the varied, dominating species that they are today.

Recent studies have shown that jellyfish population blooms are becoming more common and are continuously increasing in size, posing a threat to the natural balance of marine ecosystems and human beings as a whole, with increases as large as 94,000 tons escalating to 400, 000,000 tons in wet weight over a 100 km area in just 5 years.

Due to climate change and overfishing of other species, there is a lot of evidence that jellyfish populations are growing in some locations. As a result, it’s been suggested that they’re on the rise all over the world. 

However, we just lack the hard facts necessary to state with any certainty what is happening to the majority of these populations at this time.

Another unsolved enigma is the significance of jellyfish in ecosystems. Until recently, it was considered that jellyfish were only consumed by the rare turtle or sunfish, and that they did not contribute much to the food chain. This raised fears that as jellyfish populations grew, natural controls would be lost, and ecosystems would become jelly-dominated.
