Ecology of Abra alba

Main Ref.	Degraer, S., J. Wittoeck, W. Appeltans, K. Cooreman, T. Deprez, H. Hillewaert, K. Hostens, J. Mees, E. Vanden Berghe and M. Vincx, 2006
Remarks	Inhabit sandbanks and inshore areas (Ref. 96352). Common in near-coastal zone, rarely further than 30 km off the coast. Found buried deep in almost all sediment types but prefer fine-grained to muddy substrates; rare in coarse substrates. Feeds through its long, individually separated and stretchable siphons (Ref. 7882). Known as a surface deposit feeder (Refs. 96214, 96292).
