Braarudosphaera bigelowii is a coastal coccolithophore in the fossil record going back 100 million years. The family Braarudosphaeraceae consist of single-celled coastal phytoplanktonic algae with calcareous scales with five-fold symmetry, called pentaliths. With 12 sides, it has a regular dodecahedral structure, approximately 10 micrometers across.[2]
B. bigelowii is reported to have formed an endosymbiotic relationship with UCYN-A2, which allows B. bigelowii to fix nitrogen and convert it into compounds useful for cell growth.[3][4]
The genus name Braarudosphaera is in honour of Trygve Braarud (1903–1985), who was a Norwegian botanist. He specialized in marine biology, and was affiliated with the University of Oslo.[5]
