In an unusual event in Tamil Nadu at Tuticorin, around 100 baleen whales have been stranded in shallow waters and sand on 11th January night. The fishermen noticed this unusually large pod of whales stranded in the beaches near Manapadu and Kallamozhi villages.
These whales appear to be completely disoriented as they are coming back to the shore even when pushed back to the water by the fishermen.
When one whale gets stuck in the shallow shore others hearing its distress call try to come its rescue and get stranded. However, in this case since they are repeatedly coming back to the shore, they may have got disoriented by the Navy sonars or some experimentations by the Navy. In the past, such kinds of catastrophic standings have been witnessed due to experimentations of the US Navy.
The whales depend on their advanced echolocation modes which are even more sophisticated than the sonars used by our navies. However, the man-made sonars and sounds of other equipment in water play havoc with them. There are specific frequencies which just can “jam” them and make them disoriented and get them to the shores.
The bodies of the whales are designed based on the buoyancy of water. When a whale gets struck in shallow water, the reduced buoyancy places enormous stress on its body. The huge weight of their bodies push down the vertebrae which is not designed to support such weight. Their lungs also gets compressed. Heavy internal bleeding occurs and it is a sureshot case of death unless they are pushed back into water immediately.
