Karenia是一个至少包含12种海洋无甲藻的属。该属的物种可以在世界各地的海洋和沿海沃茨中找到。它们通常数量稀少，但偶尔会在沿海沃茨形成大片水华。大多数Karenia物种在开花时产生各种毒素，可以杀死鱼类和其他海洋生物。除了毒性外，一些Karenia花通过产生缺氧引起动物死亡。至少有一个种，K.短吻贝毒，产生短吻贝毒，不仅杀死鱼类、海洋哺乳动物和其他动物，而且引起神经毒性贝类中毒和人类呼吸窘迫。脂溶性的短吻海豚毒素可以通过鱼类的食物链向上生物放大到海豚等食肉动物，杀死它们。Karenia腰鞭毛虫生长缓慢，因此物理浓缩机制可能对水华的发展很重要。在时间和空间上，水华都是非常零星的，尽管大多数往往发生在夏季或秋季的锋面地区。目前，我们对水华的原因和预测能力的理解很差。鉴于最近发现的新物种，未来可能会发现新的Karenia物种和毒素。
Karenia is a genus containing at least 12 species of marine unarmored dinoflagellates. Species of the genus can be found throughout the world in both oceanic and coastal waters. They are usually sparse in abundance, but occasionally form large blooms in coastal waters. Most Karenia species produce a variety of toxins that can kill fish and other marine organisms when they bloom. In addition to toxicity, some Karenia blooms cause animal mortalities through the generation of anoxia. At least one species, K. brevis, produces brevetoxin that not only kills fish, marine mammals, and other animals, but also causes Neurotoxic Shellfish Poisoning and respiratory distress in humans. The lipid soluble brevetoxin can biomagnify up the food chain through fish to top carnivores like dolphins, killing them. Karenia dinoflagellates are slow growers, so physical concentrating mechanisms are probably important for the development of blooms. The blooms are highly sporadic in both time and space, although most tend to occur in summer or fall months in frontal regions. At the present time, our understanding of the causes of the blooms and ability to predict them is poor. Given the recent discovery of new species, it is likely that new Karenia species and toxins will be discovered in the future.
