Dinobryon

Dinobryon can exist as free-living, solitary cells or in branching colonies.

Ecology

Though most commonly found in freshwater lakes and ponds, Dinobryon have also been documented flourishing in lotic and estuarine habitats.

Large blooms of Dinobryon are documented most commonly in oligo- to meso- trophic temperate lakes and ponds, though they have also been observed in eutrophic waters. Such blooms regularly occur during springtime at the onset of thermal stratification, and commonly occur following a diatom bloom. The blooms are initiated from resting siliceous spores called statospores that lay dormant on the lake bottom through the winter. Increased spring insolation causes them to germinate, producing amoeboid cells that generate two flagella and encase themselves in a vase-like cellulosic lorica. These motile cells rise into photic waters where they proliferate.
