SM1.2 Anchialine pools

SM1. Subterranean tidal biome

Profile summary

Brief description

Anchialine pools are brackish surface water bodies that have a subterranean connection to the sea. They are associated with carbonate substrates and lava flows on the coast and have a stronger terrestrial influence than other subterranean systems. Exposure to the surface enables algal primary producers to inhabit the water column and the benthos. Diversity and productivity of these aquatic ecosystems increases with age and connectivity to the sea. Some anchialine pools are highly insular, with molluscs and crustacean species found nowhere else.

Key features

Open pools with subterranean connections to the sea and groundwater, and dynamic, diverse trophic networks.

Overview of distribution

Limestone, basalt and more rarely lithic substrates coastal regions globally.

Map description

Indicative distributions of Anchialine caves and pools were based on mapped areas of carbonate rock outcrop (Williams & Ting Fong 2016) and lava flows intersecting the coast, which were aggregated within a template of 1-degree grid cells..
