Traditional sperm whale identification has long relied on photographing tail flukes from boats, capturing the distinctive notches and patterns that make each whale unique. However this method has a significant limitation: researchers can only identify whales when they perform their characteristic deep dive, raising their tails above the surface. Now, drone technology is opening new...

Seals are among the most fascinating creatures to call Antarctica’s icy waters and shores home. Their remote, vast habitat makes studying them a real challenge, and scientists are only beginning to uncover the secrets of these elusive animals. Among the most intriguing mysteries? Their haunting, otherworldly vocalizations. We’ve heard about the enchanting songs of humpback...

The Australian snubfin dolphin (Orcaella heinsohni) is one of Australia’s only endemic dolphin species, identified as a new species in 2005. This small dolphin is adorable, but it faces conservation threats due to its small population and coastal habitat preference. So this month, let’s celebrate the Australian snubfin dolphin and the 25th Biennial Conference on...

A new study has found both promising and worrying trends in contaminant (chemical pollution) levels in whales off the coast of Eastern Canada. The study, published in Science of the Total Environment, shows that while environmental regulations are making progress, killer whales in the region continue to face significant challenges. Despite reductions in contaminant inputs,...

In a newly published study in Seismica, researchers used instruments on land designed to monitor earthquakes (seismometers) to detect the presence of fin and blue whale calls in the Gulf of St Lawrence.   What if we could use a seismometer to detect fins whales year long? — Credit: A. Remili What is a seismometer?  Seismometers...

Marine mammals are difficult for scientists to study; they spend most or all of their lives in and around water habitats. Because of their vastness (hundreds of thousands of square kilometers) and depth (thousands of meters), marine mammal habitats are difficult for humans to access and explore. Cetaceans – whales, dolphin, and porpoises – spend...

“If a whale got close to me, could it swallow me whole?” You probably thought of this question once or twice if you ever swam in the ocean, or hopped on a whale-watching tour. To address whether whales can eat humans, we first need to understand the anatomy and behavior of different whale species. There...

The ocean is a mysterious world. Humans know more about other planets in our solar system than about the ocean floor. In fact, the diversity of whales inhabiting the ocean’s depths is among some things we do not fully comprehend yet. But thanks to new methods, such as acoustic recording and genetic testing, new species...
