Pelagia noctiluca (Semaeostomeae - Pelagiidae) is a jellyfish found in the Northeastern Atlantic, Mediterranean, Indian Ocean, and western and central Pacific. Sometimes it is commonly named Mauve stinger.
These jellyfishes are beautiful, especially when they phosphoresce. The Mauve stinger glows by producing luminous mucus from surface cells when it is knocked or disturbed by waves.
Unlike most jellyfish, the life cycle of the mauve stinger does not involve a fixed stage.
HUGE AND DEADLY JELLY REDISCOVERED 100 YEARS LATER
Not much is known about this mysterious species, measuring 50 cm long and has a powerful sting that can be felt in the water surrounding the creature.
The incredibly rare Crambione cookiihad not been seen since 1910, but has recently been discovered on the coast of Queensland, Australia, where he was captured.
His sketch has so far been the only record of the living creature and has even been used to help identify the animal by jellyfish expert Lisa-Ann Gershwin, who confirmed the existence of this unusual marine inhabitant after he was captured.
…a species of colonial porpitid hydrozoans which occur in tropical and sub-tropical waters of the Pacific, Atlantic, and Indian Oceans. Although blue buttons look similar to jellyfish they are actually a colony of numerous hydrozoan polyps. Blue buttons are typically seen drifting on the surface of the ocean where it feeds on zooplankton which drift too close. Blue button colonies consist of two main parts: the float which is a hard brown circle which keeps the colony afloat, and the colony which forms the “tentacles” of the organism, these tentacles are laced with nematocysts which are used to dispatch prey.
This colonial anemone with tentacles greenish to pinkish, can be found on rocky, tide swept shores along the Pacific coast of North America.
An interesting fact of these anemones, recently studied, is that High-intertidal individuals are exposed aerially up to 18 h each day, unlike low-intertidal individuals which may be continuously immersed over many days [read more].
