Thus, the giant jellyfish may appear "invisible" or glow orange very faintly in its surroundings, depending on the depth of the water. Furthermore, their bodies being made of either spongy tissue or jelly allows for the species to withstand the enormous deep ocean pressure of 40,000 kPa (5,800 pounds per square inch).
Noctiluca scintillans is a marine species of dinoflagellate that can exist in a green or red form, depending on the pigmentation in its vacuoles.It can be found worldwide, but its geographical distribution varies depending on whether it is green or red.
The rarely encountered deep-sea jellyfish Stygiomedusa gigantea is another candidate for "largest jellyfish", with its thick, massive bell up to 100 cm (3 ft 3 in) wide, and four thick, "strap-like" oral arms extending up to 6 m (19 + 1 ⁄ 2 ft) in length, very different from the typical fine, threadlike tentacles that rim the umbrella of more ...

Most species appear to be gonochorists, with separate male and female individuals. The gonads are located in the stomach lining, and the mature gametes are expelled through the mouth ...
