At around 190 tonnes, the mighty blue whale is famous for its low frequency singing and being the bulkiest animal on the planet today. It’s also long been thought as the heaviest animal to ever exist – but this status may have finally changed. Today, scientists have revealed a species of ancient whale, called Perucetus […]

Avian Flu Outbreaks in Marine Mammals Mark New Era for Deadly Virus
Last June, the phones at Marine Mammals of Maine began ringing — a lot. People walking the craggy shoreline of Casco Bay, which stretches north and south of Portland, were reporting sick or dead seals. Late spring and early summer, as pups begin to set off on their own, are usually the rescue and rehabilitation […]
Dolphin Populations Around Hong Kong Dropped 80% in 15 Years Likely Due to Noise Pollution
In the last 15 years, dolphin populations around Hong Kong have dropped over 80 percent, likely due to noise pollution, World Wildlife Fund (WWF) reported. Dolphins rely on sound to socialize and hunt in the ocean. However, a noisy environment can inhibit their ability to do these vital tasks. The sea surrounding Hong Kong is […]
Three Dolphins Released Back into Ocean After Spending Years of Captivity in Amusement Park
Three bottlenose dolphins were rescued from a confined amusement park and now have been released back into the ocean to live out the rest of their days swimming free. The three dolphins, Johnny, Rocky, and Rambo were rescued from an abusement park resort hotel. Before this, the poor dolphins were forced to perform in a […]
Male Dolphins Seen Playing ‘Wingman’ to Help Each Other Find Mates
Humans have long been thought to be distinct from other animals in our ability to form complex, multilevel alliances in order to reach shared goals. However, new research published in the Proceedings of the National Academy of Sciences Monday shows that male bottlenose dolphins do the same thing, and they do it for a very […]
The Faroe Islands to limit dolphins killed to 500 following international backlash
The Faroe Islands will limit the number of dolphins killed in its annual hunt after it faced a backlash for the number of animals slaughtered last year. In September 2021, more than 1,400 white-sided dolphins were killed in just one day sparking international outrage. In response, the prime minister of the Faroe Islands announced that […]
Deep-sea mining could cause noise pollution radiating 500 kilometers across the ocean and harmful to marine mammals
According to scientists, projected deep-sea mining might cause noise pollution that would radiate through the ocean for hundreds of kilometers, generating a “cylinder of sound” that would go from the surface to the sea bed. One mine’s noise alone could travel 500km (more than 300 miles) in calm weather, according to research by scientists from […]
‘Forever chemicals’ are now found not only in whales but also in human lungs!
Scientists detected a strange effect on the stress hormones of North Atlantic right whales in the aftermath of 9/11. Ships are abundant in our oceans, yet there was a huge slowdown in traffic throughout the North Atlantic eastern seaboard immediately after the planes flew into the twin buildings, lowering undersea noise. While the rest of […]
