Dwarf foraminifera off Kerala, India: A response to mudbank formation
MetadataShow full item record
During the monsoon season, a mudbank forms off Alleppey, a coastal district in Kerala. The mudbank forms in the littoral waters within 15 m water depth. It is a small coastal zone with water being unaffected by monsoon waves roughness. Apart, from the peculiar calmness, the water column in mudbank has very high quantity of suspended sediments. With these unique settings, mudbank defines a peculiar marginal marine environment having rich fish catch and is the source of livelihood for fishermen in Kerala during the lean fishing period of monsoon. Here, we have studied the effect of mudbank formation on benthic foraminiferal morphology. The surface sediment samples from the area were analyzed for foraminifera. The maximum diameter/length/ width of foraminiferal species present in the mudbank were compared with the type species.
