Long-lived sharks challenge ageing theory

Greenland sharks can live to be over 400 years old. What can they tell us about ageing? Brittney G. BorowiecBrittney is a PhD candidate at McMaster University in Hamilton, ON, Canada, and joined Oceanbites in September 2015. Her research focuses on the physiological mechanisms and evolution of the respiratory and metabolic responses of Fundulus killifish […]

Let’s Ghost Fishing for Halloween!

Ghost fishing is ghastly because it creates underwater graveyards for wildlife. The authors covered here wrote a new review of gear entanglement among mammals, reptiles, and sharks. Find out what they discovered by reading today’s post! Rebecca FlynnI am a graduate of the University of Notre Dame (B.S.) and the University of Rhode Island (M.S.). […]

Ancient swimmers: Greenland sharks live for centuries

Using radiocarbon dating, scientists have discovered that the Greenland shark can live longer than any other known vertebrate. How long have some of these individuals been alive? Sean AndersonI am a first year MS candidate at the University of Rhode Island, Graduate School of Oceanography. I am interested in plankton ecology and the dynamics within […]

Marine Educator Conference Highlights: Glowing jellyfish, bad petitions, lost sharks & affordable VR

An ocean pharmacy made possible by jellyfish, the danger of bad petitions, the importance of understanding ‘lost sharks’, and affordable virtual reality–all highlighted in this post covering just a sliver of the National Marine Educators Association Annual Conference! Megan ChenI graduated with a Masters of Coastal & Marine Management from the University of Akureyri in […]

Why don’t sharks go deep?

Happy Shark Week! Today we examine a persistent and interesting biogeographical puzzle: why are there so few deep sea sharks? Brittney G. BorowiecBrittney is a PhD candidate at McMaster University in Hamilton, ON, Canada, and joined Oceanbites in September 2015. Her research focuses on the physiological mechanisms and evolution of the respiratory and metabolic responses […]

Is ‘Shark Week’ Good or Bad for Sharks?

‘Shark Week’ has become a staple of summer television. It is currently the longest continuously running series on television. It is also a rare example of quality scientific research (in any field) getting prime time television coverage. However, scientists and conservationists have highly criticized Shark Week in recent years for ‘fear mongering’ tactics. What does […]

Tracking the movements of a heavily fished Fijian shark

The silvertip is a reef shark targeted for its fins. Scientists tagged a Fijian silvertip to learn more about what depths and temperatures it likes to hang out in. Lis HendersonI am studying for my doctoral degree at the Stony Brook University School of Marine and Atmospheric Sciences. My research addresses fisheries and climate change […]

Fear and Floating in the Atlantic

Does fear of predation alter sea turtle behavior? Researchers put an ecological model to the test by using large-scale movement patterns of sharks and sea turtles and found something unexpected. Gordon OberPostdoctoral Researcher, Claremont McKenna College I am currently a postdoc at Keck Sciences, Claremont McKenna College. I work with Dr. Sarah Gilman, measuring and […]

Catfish sharks on catnip? Nope, just ocean acidification

Researchers from the University of Gothenburg in Sweden found that ocean acidification may cause hyperactivity in catfish sharks. Lis HendersonI am studying for my doctoral degree at the Stony Brook University School of Marine and Atmospheric Sciences. My research addresses fisheries and climate change in the Northwest Atlantic. In my free time, I like to […]

Cartilaginous Conundrum: Are Sharks and Skates Safe to Eat?

While smooth dogfish may not be on your list of favorite seafood, cartilaginous fish (mainly sharks and skates) may increasingly find their way onto your dinner plate due to the decline of more traditional fisheries. While increased demand for these species as a food item could help struggling seafood industries, recent proposals to use dogfish […]

Shark Date.

Carbon age dating of growth bands in white shark vertebrae reveal white sharks are older than originally thought and suggest a high threat of anthropogenic consequences to their death. Anne M. HartwellHello, welcome to Oceanbites! My name is Annie, I’m a marine research scientist who has been lucky to have had many roles in my […]
