Gonyaulax
Gonyaulax (/ɡɒnˈjaʊlæks/) is a genus of dinoflagellates, a type of marine plankton. It is known for its role in producing red tides, which can cause harmful algal blooms.
Etymology
The term "Gonyaulax" is derived from the Greek words 'gonia', meaning 'angle', and 'aulax', meaning 'furrow'. This refers to the distinctive grooves or furrows found on the theca of these organisms.
Description
Gonyaulax species are unicellular and possess two flagella for movement. They have a unique form of nucleus known as a dinokaryon, which is characteristic of dinoflagellates. Some species of Gonyaulax are bioluminescent, producing light when disturbed.
Ecology
Gonyaulax species are found in marine environments worldwide. They play a significant role in the marine food chain, serving as a food source for various marine organisms. However, under certain conditions, they can multiply rapidly to form red tides. Some Gonyaulax species produce toxins, which can accumulate in shellfish and pose a risk to human health when consumed.
