Trusted: edited by a thematic editorAuthority For the correct author citation see Throndsen, J. 1996. Note on the taxonomy of Heterosigma akashiwo (Raphidophyceae). Phycologia 35: 367 [details]

Trusted: edited by a thematic editorDistribution Heterosigma akashiwo is distributed almost worldwide, from the Arctic to the tropics.The available evidence has shown very little variation in rDNA sequences (>99.8% similarity) [details]

Trusted: edited by a thematic editorHarmful effect Mortality of fish. There is disagreement regarding the cause(s) of the fish kills.  [details]

Trusted: edited by a thematic editorIdentification H. akashiwo is distinguished from Olisthodiscus luteus by its only slightly flattened cells versus the very flattened cells of Olisthodiscus. Also Heterosigma cells rotate during swimming while Olisthodiscus does not.
Cells of H. akashiwo are slightly longer than wide, measuring 11-25 micrometer in length. The newly described species H. minor is almost round and measures 7-12 micrometer in diameter.
In fixed samples, H. akashiwo can be difficult to identify (see image below). It may be confused with other species whose cells contain several yellow or yellow-brown chloroplasts such as Pseudochattonella or naked stages of other silicoflagellates.  [details]

Trusted: edited by a thematic editorIdentification In the period 1971-c.1985, this species was often misidentified as Olisthodiscus luteus. [details]
