Welcome to the Wonderful World of
Pyrocystis fusiformis

I bet you're beyond ecstatic to find an entire website dedicated to this spectacularly bioluminescent marine organism. Perhaps you've always wanted to know how this organism reproduces or how something so tiny survives in such a big environment. Thanks to Organismal Biology at University of Wisconsin - La Crosse, the production of this website is possible. Now all you've ever wanted to know about Pyrocystis fusiformis is right at your fingertips.

It is a phytoplankton, which basically means it is a tiny organism in the ocean that moves with the currents and conducts photosynthesis. Pyrocystis is unicellular and immobile for the majority of its life cycle. Through a chemical reaction that occurs within its cell, it can produce a flash of light, usually at night. This is called bioluminescence. When a whole bunch of Pyrocystis fusiformis organisms congregate together and start bioluminescing all at once, it produces a brilliant light display in the ocean. Due to "armored" plates located underneath the plasma membrane and its bioluminescent ability, we refer to Pyrocystis fusiformis as "A Knight in Shining Armor."

Pyrocystis fusiformis is important because it is a major producer in the world's oceans. Through photosynthesis, it produces a large amount of oxygen and consumes carbon dioxide. This influences the concentrations of oxygen and carbon dioxide in Earth's atmosphere.

On this website, you can find a whole bunch of information all about Pyrocystis fusiformis, including its taxonomic classification, where it lives, its life cycle, and how it interacts with other organisms (including us). So, indulge your curiosity! Satisfy your craving for knowledge! Go forth and delve into the life of Pyrocystis fusiformis!
