Species of the genus are a group of marine protists that are commonly found in coastal waters. Some are known as harmful microalgae that form noxious blooms and cause massive fish mortality in finfish aquaculture. In Malaysia, blooms of have been recorded since the 1980s in the Johor Strait.

- Fisheries in Southeast Asia have suffered due to damage caused by the Chattonella red tide, with research identifying two distinct species in the region: Chattonella marina complex and Chattonella subsalsa.
- Molecular and morphological studies of additional strains have revealed five intrageneric clades within the genus Chattonella, including two new clades found in Thailand and Peninsular Malaysia, which showed significant genetic differences from previously identified clades.
- The new clades, characterized by distinct chloroplast shapes and cell features, are proposed to be two new species: Chattonella tenuiplastida and Chattonella malayana.
In 2015, a remarkably high density bloom of Alexandrium minutum occurred in Sungai Geting, a semi-enclosed lagoon situated in the northeast of Peninsular Malaysia, causing severe discoloration and contaminated the benthic clams (Polymesoda). Plankton and water samples were collected to investigate the mechanisms of bloom development of this toxic species. Analysis of bloom samples using flow cytometry indicated that the bloom was initiated by the process of active excystment, as planomycetes (>4C cells) were observed in the early stage of the bloom.
