Description

LM image of a silicoflagellate of the Dictyocha genus, species is speculum.

Dictyocha is a genus with a small group of reported extant species, however thirty extant marine species are reported for all the three genera of silicoflagellates. Well preserved fossil record back to the Cretaceous (120 MYA). Presumed only photoautotrophic; golden-brown chloroplast. In only one of three life stages do they form a silica skeleton. Two flagella; one very small, one long.
