In the first study of it’s kind, scientists have been able to analyse the diet of an endangered Killer Whale population based on fecal samples, with salmon showing to be their primary food source. Prior to this study, diet inference was primarily based on analysis of prey remains consumed by the whales at the surface, and it […]

According to new research, Parabens, a form of preservative widely used in cosmetic and pharmaceutical products, have begun showing up in the tissues of  various marine mammal species, including dolphins, sea otters and polar bears. The preservative is found in shampoos, commercial moisturisers, shaving gels, personal lubricants, topical/parenteral pharmaceuticals, spray tanning solution, makeup, and toothpaste and  is used to prevent bacterial growth […]

Whaling, the act of humans hunting whales (cetaceans) for their meat, bones and blubber,  has been occurring across the globe for millennia. A once legitimate source of income and nutrition, whaling has now been outlawed in most countries worldwide due to numerous species being hunted to the brink of extinction. It’s still undertaken both legally and […]

The varied breathing modes of different shark species affect the chances of them dying during fisheries capture, a new study suggests. A team of researchers from Monash University, analysed data on over 80 species of shark and ray that were accidentally caught by commercial fishing techniques including longlines, gillnets, and trawls. When this occurs, the caught individuals […]

A rare nautilus called Allonautilus scrobiculatus has been sighted for the first time in three decades. Until now, only two people had ever laid eyes on it. Peter Ward, a biologist at the University of Washington and colleague Bruce Saunders of Bryn Mawr College identified Allonautilusin 1984, and Saunders made another brief sighting in 1986, but it […]

Whales may be able to develop decompression sickness, the same ailment experienced by scuba divers who surface from a dive too rapidly, according to a new study. Researchers from the University of North Carolina Wilmington investigated how marine mammals’ tissues – specifically, fat deposits in the jaws of toothed whales that are used in echolocation – absorb […]

For the first time, scientists have sequenced the genome of an octopus species, revealing surprising clues about the evolution of the cephalopod’s brain and behaviour. Researchers from the University of Chicago, the University of California, Berkeley, the University of Heidelberg in Germany and the Okinawa Institute of Science and Technology in Japan assembled and published […]
