of its shell.
These bivalves create nests through the use of byssal threads to bind small stones, shells and other detritus together, enclosing themselves as form of protection. Individual nests expand over time, eventually overlapping with other nests and consequently forming expansive reefs. Holes in the reef allow fresh seawater to flow through, preventing stagnation. These reefs support a diverse marine ecosystem with one study showing six nest complexes supporting 19 species of algae and 265 species of invertebrates.
