Researchers claim that malnutrition may cause the mass stranding of humpback whales in Western Australia.

Recent incidents indicate that most of the stranded whales are calves [kavs, kahvs] or newborn whales. Veterinary researchers from Murdoch [MUR-dok] University have conducted necropsies on a number of calves. After analyzing the blubber of the carcasses, researchers discovered that many of the whales were undernourished because of low fat content.

Blubber is important to the survival of whales. Carly Holyoake [HOHL-yohk], one of the researchers, said that blubber is essential for whale survival. It provides energy, regulates temperature, and enables whales to float on water.

Holyoake also expressed the possibility that the whales’ poor nutrition is due to the critical decline of their main food, krill. Krill has become scarce [skairs] because of the commercialized fishing and climate change. As a result, whales suffer prolonged periods of foraging, which do not only weaken them but also delays their migration.

Humpback whales are known to travel from Antarctica, where krill were once abundant, to the north coasts of Australia, their breeding ground. The lack of food, however, forces cows or pregnant whales to give birth before they reach warmer waters, which are more suitable for bearing their young.

According to reports, only two to three whale incidents are expected to occur in Australia yearly. However, the number of cases has increased at an alarming rate in recent years: 75 incidents were reported from 2008 to 2010, and in 2011, 17 humpback whales got stranded, 14 of which were calves.
