Kryptoperidinium foliaceum

Description and Significance

The external appearance of this microbe is a round, imperfect circular shape. In color, it appears to be a golden brownish. On the surface, there are many smaller circles, and important to note, there is an eyespot almost exactly in the center. The habitat of this species is typically marine environments, more specifically, areas with a hypersalinic environment, as Kryptoperidinium foliaceum thrives under hypersalinic conditions, although sometimes it can be found in coastal areas and estuaries as well. In fact, Kryptoperidinium foliaceum was first discovered in a hypersaline environment in Kuwait. There was a direct correlation between the saline concentration and the Kryptoperidinium foliaceum population, the higher the saline concentration, the higher the population.

Ecology and Pathogenesis

Kryptoperidinium foliaceum can be found in various regions around the world, including the Mediterranean Sea, the Gulf of Mexico, and the Atlantic and Pacific coasts of North America. It is a common inhabitant of coastal waters, such as shallow water lagoons, estuaries and tidal creeks. K. foliaceum tends to thrive in environments with high salinity levels, but can tolerate a great range of salinities, from fresh and brackish waters up to waters with hypersalinity. The density of the Kryptoperidinium foliaceum population and distribution in many areas has been strongly correlated with a salinity pattern, as higher salinities tend to have a higher population of K. foliaceum. High salinities have also been correlated with Kryptoperidinium foliaceum blooms. These algal blooms are harmful to the fish, invertebrates, and other marine organisms in the regions where they occur. While many dinoflagellate blooms produce toxins, K. foliaceum blooms do not, and instead cause noxious odors and kill fish and other organisms by depleting the water of its dissolved oxygen.
