Blue Button Porpita porpita, commonly known as the blue button jellyfish, is not actually a jellyfish, but is a marine organism consisting of a colony of hydroids found in tropical and sub-tropical waters of the Pacific, Atlantic, and Indian oceans.
"porpita porpita - the blue button jelly - is a neustonic species mostly found in the tropics; that is, it floats near the surface of the water. The circular disc is made of chitin and filled with gas, allowing these jellies to float. The tentacles (zooids) radiating from the disc do all the feeding."
Pelagia noctiluca, (Águilas, Spain) by Alfonso Gonzalez: In Latin, Pelagia means "of the sea", nocti stands for night and luca means light and As its name implies P. noctiluca has the ability to bioluminesce. Light is given off in the form of flashes when the medusa is stimulated by turbulence created by a ship’s motion or by waves. This flashing is only of relatively short duration and gradually fades. en.wikipedia.org/... #Jellyfish
