marks, rill marks and current crescents. Biotur-
bation structures are special attractions to nature
lovers that are witnessed in the sediment bed of
muddy and sandy beaches. These structures
result from the activities of near-shore benthic
organisms and re
works and sculptures are the anemones, gastro-
pods, crustaceans, decapods, bivalves, holothu-
roids and hemichordates. In some pockets of
Indian Sundarbans, animals such as
Macoma

,
Telescopium telescopium

Uca

ect a unique fabric work of the
biotic community on the abiotic matrix. The
main agents behind these marvellous fabric
fl
and
sp. prepare a muddy substratum
and produce bioturbation in the form of mounts,
trails and burrows (Figs.
