Ear Wax May Throw Light on Lives of Free-Swimming Species
It is for the first time that ear wax of a creature has helped scientists come across its detailed life story.
Published in the Proceedings of the National Academy of Sciences, a report has unveiled that the foot-long earwax rod of a whale has enabled scientists to enter its life tale. The life-history is being deemed to be the only one of a free-ranging animal.
The 10-inch waxy plug was derived from the blue whale's skull. It appeared akin to a striped bark portion, though it felt rigid such as a candle.
The male whale, 12, was dead. It was in 2007, when the whale aground on the California coast.
The report said that a new fat layer is annually laid down by the ear of a whale. Thereafter, foreign as well as native chemicals within the body of the marine mammal get stored with it.
The team is of the hope that these waxy diaries could pave a way for understanding a free-swimming species' lives. Also, the ocean health could be comprehended.
"It looks kind of like a candle that's been roughed up a bit. It looks waxy and has got fibers. But it's pretty rigid than one would think", affirmed marine biologist, Stephen Trumble from Baylor University.
