Many species of the benthic polychaetes inhabiting marine sandy beaches not only utilize the interstices of sand grains as a space to live, but also show some remarkable adaptations to the environment which is considered to be extraordinarily unstable and poor in food supply. Such polychaetes, generally including in addition larger worms apparently incapable of making their ways without removing sand grains, can be considered together an ecologically homogeneous group, viz. interstitial polychaetes (Westheide 1971). Archiannelida, an order of polychaetes primarily adapted for the interstitial life (Hermans 1969), is one of the representatives of this group. And many other genera extending over sixteen families are also known to live in mesopsammic environments (Hartmann-Schröder 1964, Laubier 1967).
