Description Species of Prymnesium can only be reliably identified to species level by examination of the organic scales on the cell surface. In . P. calathiferum the scales scales are of two types, the inner scales elliptic with inflexed rims, the outer basket shaped. [details]From regional or thematic species database
Distribution This species was described from New Zealand but was subsequently found in France [details]
Harmful effect Fish and shellfish mortality. [details]
Identification Prymnesium calathiferum may be separated from the other species of Prymnesium by several features. Firstly, P. calathiferum has elaborate wicker-basket-like external scales which are unique to this species, and secondly, it has the greatest ratio of flagellar to cell length (2.1-3.0) and the lowest ratio of haptonema to flagella length (0.16) of all known Prymnesium species (Chang and Ryan, 1985).
