Anchialine Pools

Type: Habitat | Status: Not Evaluated | Nativeness: Endemic


Anchialine pools are landlocked, saline bodies of water with a permanent, subterranean connection to the ocean but no surface contact. This limited connectivity often promotes the evolution of unique faunal and floral assemblages with high levels endemism. On Ascension Island, anchialine pool habitats are best known for the two species of endemic shrimp that they harbour (Typhlatya rogersi and Procaris ascensionis). However, they are also home to a unique assemblage of endemic amphipods, anemones and limpets, along with large single-celled algae (Valonia ventricosa) and an unusual free-living form of the coral Favia gravida.
