| Abstract |
Intertidal sediments in the mangrove areas near Chemaguri, Gangasagar and Harinbari of the Sagar Island, West Bengal, India register feeding traces of Macoma birmanica both on the sediment surface as radiating star-like designs, as well as in the sub-surface sediment column as slender sinuous near- vertical burrows representing their siphonal passages. Their activity is mainly restricted to muddy and silty substrates close to the high-water line. They are not recorded in subtidal regions. These slender burrows, if misconstrued as polychaete burrows in fossil record, might give an erroneous interpretation of ecology as well as palaeoenvironment. |
