The genus Gambierdiscus is a complex and diverse group of marine dinoflagellates that produce a range of bioactive compounds, including ciguatoxins and maitotoxins. These toxins can accumulate in the food chain, leading to ciguatera poisoning in humans who consume contaminated fish. Recent research has highlighted the chemical diversity within the genus Gambierdiscus, with different strains producing distinct sets of toxins. This diversity presents challenges for the development of effective detection and management strategies for ciguatera, but also offers opportunities for the discovery of new bioactive compounds with potential applications in medicine and other fields. Understanding the chemical diversity of Gambierdiscus and its associated toxins is therefore an important area of research with implications for public health and biotechnology.
