Researchers from the University of Southern Denmark have just completed a new study into the communication of Sperm Whales. Through listening to the characteristic tapping sounds (known as codas) of 7 sperm whales in the waters off the Azores, the team discovered that these sounds serve as a form of communication between individuals. This discovery is significant as […]

Overfishing has dramatically depleted sharks and other large predatory fishes worldwide except for a few remote and/or well-protected areas. The islands of Darwin and Wolf in the far north of the Galapagos Marine Reserve (GMR) are known for their large shark abundance, making them a global scuba diving and conservation hotspot. Researchers from the Charles Darwin […]

The impact of climate change on the earth’s oceans has been studied extensively over the past two decades. With an increasing amount of evidence detailing it’s negative effects on the marine environment, scientists are striving to identify ways to repair the damage that has already been done and to find solutions to prevent future damage. One of the primary impacts of […]

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 […]
