Types of Jellyfish

Jellyfish are intriguing creatures with an extraterrestrial appearance, a proclivity for extreme depths, and a strange appearance.

Just a tiny fraction of the 2000 species of jellyfish has been discovered so far, and there is still a lot more to find. Sea jellies are gelatinous nonfish that lack hearts, blood, and brains. This article offers you a curated list of different varieties of Jellyfish, as well as some intriguing information about them.

What is Jellyfish?

Jellyfish are alien-like creatures with extraterrestrial characteristics and a preference for deep waters. They are lovely to look at. These gelatinous nonfish lack brains, blood, and hearts, and are sometimes referred to as sea jellies.

They may be of various sizes, colors, forms, and behaviors. (Some, for example, sting humans while others do not.) More about the marine creature is being learned all of the time.

Here are some interesting and gorgeous jellyfish species.

Crystal Jellyfish

The Crystal jellyfish comes in first place. This jellyfish species is totally colorless and gets its name from being found in the seas around North America’s shore. At day, this exquisite specimen is crystal clear and has approximately 150 tentacles surrounding its glass-like bell. This openness, on the other hand, hides a more positive aspect.

Crystal jellies are vividly luminous jellies with brilliant points around the umbrella’s border, according to the Monterey Bay Aquarium.

Aequorin, a calcium++ activated photoprotein that produces blue-green light, and an auxiliary green fluorescent protein (GFP), which accepts energy from aequorin and emits it as green light are the components required for bioluminescence.

By inserting the GFP gene from the crystal jelly into mice, scientists have created ‘green mice’ that glow green when hit by blue light. Scientists find and study genes faster thanks to the glowing protein, a widely used biological highlighter.

Moon Jellyfish (Aurelia aurita)

You may have seen a few varieties of jellyfish washed up on the beach during your beach trips. Because of their propensity to stay near the shore, Moon Jellyfish are frequently found in this way.

These jellies are also poor swimmers, according to legend. Because of their small size, they are vulnerable to marine predators like the leatherback turtle. Because of the minimal nutritional value of each jelly, the aforementioned predators must consume huge volumes of Moon Jellyfish.

Even the most experienced marine biologist is fascinated by the Moon Jellyfish’s life cycle. Sexual and asexual reproduction are used by these jellies to breed or mate. As a result, their particular approach allows them to thrive along the coast. They may also survive in a variety of weather conditions throughout the year.

You can also relax knowing that you won’t be stung by a Moon Jellyfish. Their stinger is harmless, and it has no deadly side effects. If you don’t want to suffer from their sting, you should continue to keep them at a distance.

Cauliflower Jellyfish

Because of the wartlike projections on its bell, the cauliflower jelly (Cephea cephea) is called that. The crowned jelly, sometimes known as the Indo-Pacific or mid-Pacific jelly, is an oceanic species whose size ranges from two to three feet in diameter. It’s found off the coast of West Africa in the Indo-Pacific and Atlantic oceans.

Lion’s Mane Jellyfish

Lion’s mane jellies, which have up to 1200 tentacles and include a lot of neurotoxins, are the world’s largest jellyfish species. Eight groups of 70 and 150 tentacles each emerge from beneath the bell.

Scientific Name: Cyanea capillata

The smaller lion mane jellyfishes are dark red to dark purple, and the bigger ones are tan to orange.

Arctic, Northern Pacific, and Northern Atlantic jellyfish species are all found in the cold water habitat of Lion’s mane jellies.

When they dive into the water column, they use their long, thin tentacles to capture their food like a net. Zooplankton, fish, other jellyfishes, and tiny crustaceans are the primary food of lion’s mane jellyfish.

Giant Jellyfish, Hair Jellyfish, and Arctic Red Jellyfish are some of the other names for this species.

Are they painful to touch? Lion’s mane jellies are infamous for causing painful stings, with allergic symptoms that may be life-threatening.

Box Jellyfish

The sophisticated species The Box Jellyfish The Box is one of the most poisonous sea creatures, native to the shallow waters of Northern Australia and the Indo-Pacific region.

The 15 10-inch tentacles of the pale blue and transparent cubed bell are covered in roughly 5,000 stinging cells.

Any surviving victims will suffer significant scarring after the sting is extremely painful and deadly. One year is its average lifespan.

The majority are 10 feet long by 10 feet broad and weigh up to 4.4 pounds. They can travel at a speed of four knots through water.

Upside-Down Jellyfish

In contrast to most jellyfish, upside-down jellyfish have a different behavior. They sit with their bell on the ground, extending their tentacles up to capture food instead of floating bell-up in the ocean. In tropical seas all around the globe, upside-down jellyfish are most often found in protected coastal areas.

The defense and hunting mechanism of upside-down jellyfish is unique. To capture prey and ward off predators, these jellyfish discharge mucus containing nematocysts into the water.

Although a single upside-down jellyfish’s venom isn’t particularly powerful, if the rest of the colony releases envenomated mucus, the water becomes hazardous for tiny fish.

A little stinging sensation in the water has been reported by people swimming through these waters, which is most likely caused by the upside-down jellyfish’s mucus.

Bloodybelly Comb Jellyfish

Our next contender is the Bloodybelly Comb jellies, who are technically comb jellies and are only quite distantly related to the jellyfish and rank high in the charts for being cool and beautiful. This one is a non-fatal Comb jelly to humans and does not feature the renowned jellyfish stinging tentacles that others do.

The cilia, or tiny hair-like projections that beat back and forth to help propel it through the water, are what they lack in tentacles but make up for in terms of movement. A beautiful sparkling light display consisting of colors is created by the movement of the cilia.

The Bloodybelly Comb jellies turn red color when in deep water, which makes them practically unnoticeable, despite their reputation of being a “showoff.

The red belly of this Bloodybelly comb also helps to mask the bioluminescence glow of its prey and keep it extra safe from the attention of its predators, which makes it seem like black in the depths of the ocean.

Black Sea Nettle Jellyfish (Chrysaora achlyos)

The Black Sea Nettle Jellyfish, like the Lion’s Mane Jellyfish, occupies a spot on the list of largest jellyfish species. When diving into Southern California’s deep Pacific seas, you may see them.

Remember to keep clear of the Black Sea Nettle Jellyfish’s lengthy tentacles if you do find one. Getting caught in the jellyfish stingers, which can stretch up to 25 feet long, is unimaginable.

The Black Sea Nettle Jellyfish piques the attention of most marine scientists, as it does for most jellies in open water. This interest stems from the fact that this sort of jellyfish is extremely difficult to keep captive.

Mangrove Box Jelly

The mangrove box jelly (Tripedalia cystophora) is a tiny jelly with a cube-shaped medusa that’s unusual among jellies in general. It grows to be barely the size of a grape and is one of the smallest jellies in the sea. The mangrove box jelly can swim quickly due to its distinct squareness.

Flower Hat Jellyfish

With black, opaque pinstripes spreading from the middle to the edge on a transparent bell and multicolored tentacles extending from it, flower hat jellyfish are intriguing to view. They paralyze tiny fish with venom and devour them using these gleaming, fluorescent-tipped tentacles. They’re a brilliant jellyfish species that produces dazzling fireworks under a blacklight in the depths.

Scientific Name: Olindias formosa

Color: Flower hat jellies have multiple colours

They may reach a diameter of 15 cm (6 inches).

Jellyfishes prefer shallow coastal waters where they live in flower hats. On the ocean floor, they are found near kelp or seagrass.

Little, shallow-dwelling fish, diatoms, and zooplankton make up their diet.

Do they bite? The stinging of the flower hat jellies is painful and causes a colorful rash.

Pink Comb Jelly

Pink Comb jellies swim at the surface of shallow and deep waters in the lower Chesapeake Bay region during late summer and fall.

These sea creatures, which resemble golf balls and have combs that generate colorful iridescent streaks when swimming in the sea, are the size of a golf ball.

Their tentacles contain colloblasts that make a gluey, sticky substance to trap their prey instead of stinging.

They can fertilize themselves since they have both male and female organs. Comb Jelly feeds on sea walnuts, planktonic species, and fish larvae and ranges in color from pink to brownish translucent.

Nomura Jellyfish (Nemopilema nomurai)

The Nomura jellyfish grows up to six feet (1.82 m) in diameter and weighs over 400 pounds (181.43 kg) when mature. It is one of the world’s largest species of jellyfish. Jellyfish blooms caused by Nomura jellyfish may destroy fish populations in the oceans between China and Japan.

Because of the gigantic volume of Nomura jellyfish that has invaded China and Japan, specialized study teams have been created to investigate why this species expands so much and how the population may be decreased.

A combination of hydroelectric projects and farming along the Yangtze River, which has created enriched nutrient habitats in the Sea of Japan, these scientists believe Nomura jellyfish may grow so large.

Nomura jellyfish have a unique defense mechanism, even though it should be simple to remove jellyfish blooms from the water. They emit billions of sperm and eggs, which attach to the ocean bottom and develop into more jellyfish, when they sense danger.

White-spotted Jellyfish

The White-spotted jellyfish is ranked fourth on the list. Any jellyfish stings from its stinging cells are harmless to us humans because these jellies have very little venom. In reality, the venom of the white-spotted jelly isn’t used to capture food!

What do jellyfish eat? Filter feeders, such as oysters and sponges, are what they’re called. Every day, they are able to filter over 50 cubic meters of ocean water! The only disadvantage of this jellyfish species is that a swarm (or bloom) of these jellies may sweep up all the zooplankton in an area. Greedy little creatures!

The tiny marine life that the fish and crustaceans consume is in short supply. Their hungry appetite poses a minor challenge for the native species from shrimps to corals in such places where the white-spotted jelly is regarded to be an invasive species, such as the Gulf of California, Caribbean Sea, and Gulf of Mexico.

Irukandji Jellyfish (Carukia barnesi)

The small size of this jelly isn’t deceiving. Among all jellies in the open seas, experts dubbed the Irukandji Jellyfish the most dangerous stinger. Why is it that way, though? Now, the Irukandji Jellyfish’s venom causes significant agony in most of its victims, and they do not recover. The Irukandji Syndrome was named after those who survived such a horrible ordeal.

An Australian aboriginal tribe gave the Irukandji Jellyfish its name. This is due to the fact that this form of jellyfish first appeared in Cairns, Australia’s coastal seas, where the tribe lives. The Irukandji Jellyfish sting causes you to feel enormous long-lasting pain after a while.

At first, the sting causes a little discomfort. The sting will start to release sweat after approximately 10 minutes. Following the sting, the intense discomfort starts between 20 and 30 minutes later. In your stomach, back, limbs, and head, you’ll experience strong sensations. Vomiting and difficulties breathing are both exacerbated by this.

Seek medical attention as soon as you begin to experience symptoms. With enough pain medication and rest, you may survive an Irukandji Jellyfish.

Fried Egg Jellyfish

The fried egg jellyfish (Cotylorhiza tuberculata) got its name from where it came. It has a lighter ring around its yellow bell, which resembles an egg yolk in appearance.

The fried egg jellyfish has a truncated mouth-arm, with longer projections with disklike ends that give it the appearance of a dome dotted with purple and white stones. From summer to winter, this species is able to survive for only six months, before succumbing when the water gets colder.

Four-Handed Box Jellyfish (Chiropsalmus quadrumanus)

The West Atlantic Ocean, the Gulf of Mexico, and the Pacific Ocean are home to the four-handed box jellyfish. With tentacles up to 13 feet long (3.96 m), this jellyfish is transparent and has a bell approximately the size of a fist.

The venomous sting of the four-handed box jellyfish has been known to kill people in minutes, and it is known to be lethal to small children.

Atolla Jellyfish

The Atolla jellyfish comes in at number eight on our list. This may be found all throughout the globe and is also known as the Coronate Medusa jelly. The Atolla, like other deep sea-dwelling organisms, possesses Bioluminescent abilities.

Bioluminescence is used by most deep-sea ocean dwellers to entice prey, however it is utilized by this kind of creature to keep itself from becoming prey! The Atolla emits a succession of flashes after being hit, much like a warning siren. Predators are drawn in by the flashes this species creates.

The original attacker, rather than the Atolla, is supposed to pique the predators’ attention, allowing the jellyfish a chance to flee! This is why it has been dubbed “alarm jellyfish” by scientists.

Mauve Stinger (Pelagia noctiluca)

The Mauve Stinger’s charming blue-purple hues should never be underestimated. Their stingers can grow up to 3 meters long, despite their small appearance. They also have strong stinging tentacles, which can be a danger.

They had a parasitic relationship with amphipods, which reside inside Mauve Stingers’ ring of tentacles. The little crustaceans are tough enough to swim with the jellyfish and are therefore popular. Mauve Stingers may be seen swimming in the Mediterranean-like waters of Europe.
