1、Now many people are seeing dolphins conching.
2、So far, only one male dolphin, the individual spotted in 2009, has been seen conching.
3、If, as with sponging, conching is taught primarily by females to other females, then conching was likely an invention of single mothers trying to feed their families.
4、Unlike sponging, however, in which dolphins use sponges to find fishes hiding in mud, conching isn't yet widespread in Shark Bay.
5、Also unknown is how conching emerged: as a variation on sponging, perhaps, or in flashes of insight from creatures whose intelligence may rival our own but happen to lack fingers and hands.
