What can fossilized dolphin skeletons tell us about how whales transitioned from land to sea millions of years ago? New research describes Ankylorhiza tiedemani, an extinct species of dolphin that hunted large prey in the ancient seas of South Carolina. Julia ZehI am a PhD candidate at Syracuse University studying marine mammal communication. My research […]

VaquitaCPR: Trying to save the world’s most endangered marine mammal

What do you do when the species you’ve been working to save from extinction is down to fewer than 30 individuals? With only thirty vaquita porpoises left in the entire world, despite years of conservation efforts, emergency action needed to be taken in an effort to save the world’s smallest and most endangered porpoise.

Minke Boings: A 50-year mystery and the science of listening in the ocean

Whale sounds are weird and fascinating, but for a long time scientists weren’t even sure that whales made sounds. The history of the study of sounds made by marine animals starts with naval submarine recordings, World War II, and mysterious sounds like the minke boing. Julia ZehI am a PhD candidate at Syracuse University studying […]

Why do narwhals have tusks that make them look like unicorns? As climate change continues, what is the fate of narwhals and their enigmatic tusks? Two recent studies of these unicorns of the sea start to answer questions about their past, present, and future. Julia ZehI am a PhD candidate at Syracuse University studying marine […]

Protections with a bite: Are toothed whales sheltered by South African Marine Protected Areas?

Marine Protected Areas (MPAs) are often put into place to protect biodiversity and essential fish stocks, but toothed whales are rarely considered when deciding where to put an MPA. As South Africa looks to expand its protected areas, Jean Purdon and her colleagues set out to learn where the toothed whales are living off the […]

Tagging the deepest diving mammal: the Cuvier’s beaked whale

A few years ago, the Cuvier’s beaked whale set the record as the deepest diving mammal. At the time, not much else was known about their diving abilities. Check out what Shearer’s team has done to study these elusive divers off the coast of North Carolina. Constance SartorConstance is a graduate student at the University […]

Sleeping with one eye open: fur seals may help us understand sleep patterns

Most mammals need to catch their zzz’s to function properly. Fur seals appear to naturally go through prolonged periods of sleep deprivation without suffering obvious side effects. Researchers are studying these semi-aquatic mammals to uncover some mysteries about sleep. Ashley MarranzinoI received my Master’s degree from the University of Rhode Island where I studied the […]

Throwing Babies out with the Sea Ice: Ringed Seals Response to Ice Decline

As the Earth warms, sea ice declines. What happens to those animals who rely on the ice? Today’s oceanbites looks at one animal, the ringed seal, and how it may be affected by climate change! Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and the University of Rhode Island (M.S.). I […]

Heroic Humpbacks: Orcastrate an Escape

While watching a pod of killer whales attacking their prey, scientists noticed a small group of humpback whales come to the rescue. Why did these humpbacks risk their own safety to save another animal? Read more about how scientists are investigating this question.
