17 Most Beautiful Jellyfish Species on Earth

Jellyfish is also known as jellies or sea jellies or a stage of the life cycle of Medusozoa. Jellyfish have several different morphologies that represent several different cnidarian classes including the Scyphozoa (over 200 species), Staurozoa (about 50 species), Cubozoa (about 20 species), and Hydrozoa (about 1000–1500 species that make jellyfish and many more that do not). Jellyfish are found in every ocean, from the surface to the deep sea. Some hydrozoan jellyfish, or hydromedusae, are also found in fresh water; freshwater jellyfish are less than an inch (25 mm) in diameter, are colorless and do not sting. The jellyfish is one of the wonders of marine life.

These are large beautiful and quite attractive colors but today we are discussing some of the most common known jellyfishes. Join me as we look at 17 of the most beautiful!

4. Diplulmaris Antarctica

Diplulmaris antarctica is a species of jellyfish in the family Ulmaridae. This species grows to approximately 4 cm wide. Diplulmaris antarctica has 16 – 48 laterally compressed, white tentacles. It has reddish-orange stomach gastrodermis and flilled oral arms of the same colour.This jellyfish is normally infested with Hyperiella dilatata. These hyperiid amphipods appear as white dots on the surface of the bell, and do not appear to eat the medusa.

6. Porpita Porpita

Porpita porpita, commonly known as the blue button, is a marine organism consisting of a colony of hydroids found in tropical waters from California to the tropical Pacific, the Atlantic and Indian oceans It is often mistaken for a jellyfish, but although jellyfish and the blue buttons are part of the same phylum (Cnidaria), the blue button is part of the class Hydrozoa.

8. Blue Jellyfish

Cyanea lamarckii, also known as the Blue jellyfish or Bluefire jellyfish, is a species of jellyfish in the family Cyaneidae. This species is found in the pelagic zone off the west coast of Scotland, the North Sea and the Irish Sea, sometimes with the more common Lion’s Mane Jellyfish, (Cyanea capillata).Cyanea lamarckii has a blue or yellow tone and grows to approximately 10 to 20 cm, but specimens can grow to 30 cm. In Scandinavian seas this species rarely grows larger than 15 cm.This jellyfish has many stinging tentacles. The four mouth arms are large with many wrinkles and ripples.

11. Purple Striped Jellyfish

The purple-striped jelly is a species of jellyfish that exists primarily off the coast of California in Monterey Bay. The bell (body) of the jellyfish is up to 70 cm (27.6 inches or 2.3 feet) in diameter, typically with a radial pattern of stripes. The tentacles vary with the age of the individual, consisting typically of eight marginal long dark arms, and four central frilly oral arms.

12. Flower Hat Jellyfish

The flower hat jelly is a rare species of jellyfish occurring primarily in waters off Brazil, Argentina, and southern Japan. Characterized by lustrous tentacles that coil and adhere to its rim when not in use, the flower hat jelly’s bell is translucent and pinstriped with opaque bands, making it easily recognizable.

The flower hat jelly can grow to be about 15 cm (6 inches) in diameter. Its sting is painful but non-lethal to humans. Its diet consists mostly of small fish.

13. Cannonball Jellyfish

The cannonball jellyfish (Stomolophus meleagris) is a species of jellyfish in the family Stomolophidae. Its common name derives from its similarity to a cannonball in shape and size. Its dome-shaped bell can reach 25 cm (10 inches) in diameter and the rim is sometimes colored with brown pigment. These arms function as a way of propulsion and aid in catching prey. Cannonballs are prominent from North America’s eastern seaboard all the way to Brazil.

14. Blue blubber

The Jelly Blubber (Catostylus mosaicus), also known as the Blue Blubber Jellyfish, is the most commonly encountered jellyfish along the Australian eastern coast and large swarms sometimes appear in estuarine waters.

15. Box jellyfish

Box jellyfish are cnidarian invertebrates distinguished by their cube-shaped medusae. Box jellyfish are known for the extremely potent venom produced by some species: Chironex fleckeri, Carukia barnesi and Malo kingi are among the most venomous creatures in the world. Stings from these and a few other species in the class are extremely painful and sometimes fatal to humans.

16. Cassiopea Jellyfish

Cassiopea is a genus of scyphozoan jellyfish very commonly found in shallow mangrove swamps, mudflats, and turtle grass flats in Florida and various other similar environments around the world, where it lives usually upside-down on the bottom. Where found, there may be numerous individuals with varying shades of white, blue, green and brown.


17. Comb jellyfish

Comb jellyfish is, is not a jellyfish at all. Because Jellyfish as a species belong to the phylum, Cnidaria,Whereas, comb jellies are an entire separate phylum themselves called Ctenophora. The phylum is commonly derived from a common characteristic shared by the member species.
