Galapagos Sargasso Grass (Bifurcaria galapagensis)

This alga species was once one of the most common species growing in the lower intertidal and shallow subtidal habitats on the Galápagos Islands, but disappeared after a devastating El Niño event in 1982/83.

The species is now considered extinct. [1]
