Beware exploding whales: New Zealand
problems warning when mass stranding
Beachgoers in New Zealand have been warned to steer beyond exploding whales when the mass stranding that left many whale carcasses putrefaction on a beach within the country’s South Island.
Reuters reports that authorities are cutting holes in three hundred mouldering pilot whale carcasses, popping the dead animals “like balloons” to forestall them from exploding on the remote beach on South Island’s Golden Bay. New Zealand’s Department of Conservation cordoned off the carcasses and issued a statement warning of the chance posed by exploding whales, according to Reuters.
Popular Science explains that, as bodies decompose and bacteria break down flesh, they release gases. However, whales’ thick skin and blubber will build it tough for the gases to diffuse-- thus puncturing the aspect of their bodies can forestall explosion by material possession the gases out slowly.
Volunteers’ frantic efforts to refloat the pilot whales and the macabre scenes development on Golden Bay have garnered international media attention over the previous couple of days.
More than four hundred pilot whales swam stranded and have become stranded on Golden Bay’s Farewell Spit Th, sparking a massive operation. Just 2 days later a second pod of additional than two hundred whales became stranded, Reuters reports.
A total of around 400 whales were saved by rescuers, according to Reuters.
Dr Rochelle Constantine, a marine biologist at the University of urban center told the BBC that the shallow waters around Farewell Spit could have caused the whales to beach. The combination of water that becomes gradually shallower and soft sand could have confused the echo-location that whales use to navigate, she said.
Pilot whales are the second largest species in the dolphin family, after killer whales.
