Ashtamudi Lake (Ashtamudi Kayal) in the Kollam District of Kerala, India, is the second largest and deepest wetland ecosystem, a palm-shaped (also called octopus-shaped) large water body, next only to the Vembanad estuary ecosystem of the state. Ashtamudi means `eight coned`(Ashta = `eight`; mudi = `coned`) in the local language of Malayalam. This name is indicative of the lake`s topography: a lake with multiple branches. The lake is also called the gateway to the backwaters of Kerala. Ashtamudi Wetland was included in the list of wetlands of international importance, as defined by the Ramsar Convention for the conservation and sustainable utilization of wetlands.
