Karenia
Karenia is a genus of single-celled organisms known as dinoflagellates, which are a type of plankton found in marine environments. These microorganisms play a crucial role in ocean ecosystems, contributing to the food web and participating in photosynthesis. Some species within this genus can produce toxins that affect marine life and human health.
One of the most well-known species in the Karenia genus is Karenia brevis, which is responsible for harmful algal blooms, commonly referred to as "red tides." These blooms can lead to fish kills, shellfish poisoning, and respiratory issues in humans. Monitoring and managing these blooms is essential for protecting marine ecosystems and public health.
