The marine environment is one of the most important issues that has received a lot of attention recently and its high importance is related to ecological issues and biodiversity and maritime economies such as fisheries and fishing activities, tourism, and so on. One of the biggest natural pollutants in the seas is harmful algal blooms (HABs) caused by phytoplankton species including dinoflagellates. Marine dinoflagellates with biotoxin production potential are an emerging phenomenon that has caused growing concern in various health, economic, and fishing sectors. Important reasons for these flourishes are the entry of human pollutants such as agricultural fertilizers, sewage, non-standard activities of aquaculture and improper landfilling of household and industrial waste in coastal areas and their leachate entry into the marine ecosystem as well as climate change. Harmful dinoflagellates cause damage to the health of the marine ecosystem in two ways; either due to the high density and the creation of hypoxic conditions for aquatic animals or the secretion of biotoxins, which in both cases will lead to the death of organisms. The present study examines why and how these blooms occur and reviews the dangers to marine and human environments, and clearly demonstrates the importance of preventing pollutants from entering the oceans and continuously monitoring and monitoring harmful algal blooms.
