Genera from Udoteaceae include tufts of uncalcified and free filaments, a brush-like calcified thallus, or calcareous compact fan-shaped blades.

[5] The time it takes for the gametes to be fertilized after being released varies greatly among the green algae (Chlorophyta).

The genera Udotea, which belongs to the family Udoteaceae, can take up to ninety-six hours after the gametes are released before being fertilized.

[6] Udoteaceae's origin dates back about 216 mya (million years ago), which would be around the Late Triassic period.

[7] Three centers of diversity have been identified for Udoteaceae: The Central Indo-Pacific, the Western Indian Ocean, and the Greater Caribbean region.

Udoteaceae play a major part in the ecological system as a primary producer and as a contributor to carbonate fluxes.
