Benthic Organisms

What are the components of Marine Benthic Communities?

Components of a typical soft-bottom macrobenthic community

Except in eastern and southern shores where the shallow subtidal habitat is rocky and coral-encrusted, the majority of subtidal seabed of Hong Kong is soft and comprises an admixture of sand and mud. The detailed composition of the soft sediment varies from place to place and is one of the main factors that determines the type of bottom-dwelling (benthic) organisms which inhabits the sediment.

An ecologically healthy and stable benthic community thus sustains a diversity of marine fauna.
