Submarine caves are cryptic habitats of the littoral zone characterized by reduction or absence of light, marked oligotrophy and low water circulation. In these environments, nutrient input through freshwater seeps or current storms favor the growth of dense serpulid aggregates and associated suspension feeding organisms (bryozoans, corals, sponges and ascidians). These organisms and associated microbial communities form large aggregates and contribute to bioconstructions projecting from the walls and vaults of caves (Guido et al., 2013). Here we extend the knowledge on bioconstructions growing in cryptic marine environments with the characterization of the biotic crusts found in Fara (F) and Agios Vasilios (AV) Caves (Lesvos Island, Greece).

Abstract

Submarine caves are cryptic habitats of the littoral zone characterized by reduction or absence of light, marked oligotrophy and low water circulation. In these environments, nutrient input through freshwater seeps or current storms favor the growth of dense serpulid aggregates and associated suspension feeding organisms (bryozoans, corals, sponges and ascidians). These organisms and associated microbial communities form large aggregates and contribute to bioconstructions projecting from the walls and vaults of caves (Guido et al., 2013). Here we extend the knowledge on bioconstructions growing in cryptic marine environments with the characterization of the biotic crusts found in Fara (F) and Agios Vasilios (AV) Caves (Lesvos Island, Greece).
