Question

What are the physical features of Noctiluca?

Answer 1

Best Answer: One of the marvels of the ocean is a little creature called Noctiluca scintillans, commonly known as the seasparkle. It is a dinoflagellate, a little single-celled algae. Floating in swarms of millions these organisms cause the glowing of the sea. The archetype of a dinoflagellate has a flattened spherical body shape and is armoured by plates covered with an intricate texture. They propel themselves with two (or sometimes more) flagella. One is pointed downward, the other is running as a spiral through a groove running along the equator of the cell. Noctiluca however has a different body plan. It forms a gas bag that enables the creature to float right under the surface of the ocean. There still are two flagella although one is exceptionally thick. This large one is clearly visible while the other one is very insignificant (just noticeable in the picture above the large flagella).
