Biology
Vanvoorstia bennetiana was a small red alga. Like other members of its genus, V. bennettiana did not have significant differences in morphology throughout any phase of its life cycle. It can be distinguished from other members of its genus by its small size and by the structure of its reproductive organs. The overall structure of the alga is that of a blade with fine meshing. For much of the time it was extant, the alga was common.
The alga has only been found in two localities; both in or near Sydney Harbour. One was near the eastern part of Spectacle Island, where it was discovered between May 1 and May 15, 1855. The other was in a channel between Point Piper and Shark Island, where numerous specimens were collected in 1886.
