夜光藻（Noctiluca noculans）是世界范围内分布最广、数量最多的赤潮生物之一。它以两种形式出现。红色夜光藻是异养的，在食物网中扮演着微型浮游动物食草动物的角色。相比之下，绿色夜光藻含有一种光合共生体Pedinomonasacetylucae（一种Prasinophyte），但当食物供应充足时，它也以其他浮游生物为食。在这篇综述中，我们记录了这两种形式的全球分布，并包括其全球分布的第一张地图。红色夜光藻广泛分布于世界温带至亚热带沿海地区。它发生在约10A摄氏度至25 A摄氏度的宽温度范围内，并在较高的盐度（通常不在河口）。它在高生产力地区特别丰富，如上升流或富营养化地区，硅藻占主导地位，因为它们是其首选的食物来源。绿色夜光藻的温度范围更局限于25 A摄氏度-30 A摄氏度，主要出现在东南亚的热带沃茨，孟加拉湾（印度东海岸），阿拉伯海东部，西部和北方，红海，最近它在阿曼湾变得非常丰富。红色和绿色夜光藻在阿拉伯海东部，北方和西部的分布重叠，从绿色夜光藻在较冷的冬季对流混合，生产力较高的季节，红色夜光藻在更贫营养的温暖的夏季季节的季节性转变。
The dinoflagellate Noctiluca scintillans is one of the most important and abundant red tide organisms and it is distributed world-wide. It occurs in two forms. Red Noctiluca is heterotrophic and fills the role of one of the microzooplankton grazers in the foodweb. In contrast, green Noctiluca contains a photosynthetic symbiont Pedinomonas noctilucae (a prasinophyte), but it also feeds on other plankton when the food supply is abundant. In this review, we document the global distribution of these two forms and include the first maps of their global distribution. Red Noctiluca occurs widely in the temperate to sub-tropical coastal regions of the world. It occurs over a wide temperature range of about 10A degrees C to 25A degrees C and at higher salinities (generally not in estuaries). It is particularly abundant in high productivity areas such as upwelling or eutrophic areas where diatoms dominate since they are its preferred food source. Green Noctiluca is much more restricted to a temperature range of 25A degrees C-30A degrees C and mainly occurs in tropical waters of Southeast Asia, Bay of Bengal (east coast of India), in the eastern, western and northern Arabian Sea, the Red Sea, and recently it has become very abundant in the Gulf of Oman. Red and green Noctiluca do overlap in their distribution in the eastern, northern and western Arabian Sea with a seasonal shift from green Noctiluca in the cooler winter convective mixing, higher productivity season, to red Noctiluca in the more oligotrophic warmer summer season.
