Carcasses of Killer Whales reveal Important Fact about Specie

In more than past two years, 10 killer whales' carcasses have been found. Recently, a study has been carried out by a group of U. S. and Canadian scientists.

The study, which has been published in the journal Marine Mammal Science, has concluded that approximately 48 killer whales are expected to lose their lives on yearly basis.

The study researchers were of the view that a whale carcass is a great opportunity for researchers to know a number of important things about the specie.

Some of the many things that can be known by studying whale carcasses are prey preference, growth rates, longevity, period of reproduction, injuries, vessel collisions and gestation period, among other things.

Study researchers said that by studying whale carcass, they are also able to know about the level of pollution present in water that has been proving dangerous for the health of whales. By studying the blubber and internal organs of dead whale, researchers can know about the level of polychlorinated biphenyls.

Brad Hanson, a marine mammal biologist, from National Marine Fisheries Service, was of the view that more number of researchers wants to know about the transient killer whales. Therefore, they are trying to study their carcasses.
