The Scyphozoa are an exclusively marine class of the phylum Cnidaria, [2] referred to as the true jellyfish (or "true jellies"). The class name Scyphozoa comes from the Greek word skyphos ( σκύφος ), denoting a kind of drinking cup and alluding to the cup shape of the organism.
Some box jellyfish species' eyes appear to have evolved more focused vision in response to their habitat. [50] Pupillary contraction appears to have evolved in response to variation in the light environment across ecological niches across three species of box jellyfish (Chironex fleckeri, Chiropsella bronzie, and Carukia barnesi).
The new species was identified by its tentacles, size, DNA and other subtle physical features, the study said. Researchers also discovered a second new species of jellyfish and documented dozens ...
Staurozoa is a class of Medusozoa (or jellyfish).It has one extant order: Stauromedusae (stalked jellyfishes) with a total of 50 known species. A fossil group called Conulariida has been proposed as a second order, [3] although this is highly speculative.
Aequorea victoria, also sometimes called the crystal jelly, is a bioluminescent hydrozoan jellyfish, or hydromedusa, that is found off the west coast of North America.. The species is best known as the source of aequorin (a photoprotein), and green fluorescent protein (GFP); two proteins involved in bioluminescence.
The oceans are home to many fascinating and dazzling creatures, and recently NOAA explorers captured a mesmerizing video of one of them. Bizarre looking jellyfish captured on video during deep sea ...
The polyps of these jellyfish can grow to 1.6 cm (0.63 in) tall and their ephyrae have an average diameter of 0.4 cm (0.16 in). [13] The adult medusae are typically translucent in color [ 13 ] but the color of their gut can change based on what they eat; for example, if they eat crustaceans, they can have a pink or lavender tint to them and if ...
Scientists in Spain have unlocked the genetic code of the immortal jellyfish - a creature capable of repeatedly reverting into a juvenile state - in hopes of unearthing the secret to their unique ...
