Species composition and biodiversity

Muddy sand habitats tend to support a relatively poor diversity of species, which are usually found in high abundances. Species present are predominately sessile tube-dwelling polychaetes with bivalves also well represented (Atkins 1983). Some species characteristic of subtidal areas may also occur.
