Electronic Tagging and Tracking Marine Animals Supports Conservation

Understanding and predicting animal movement is important as it is central to establishing effective management and conservation strategies [1].

Shark Species Thought to Be Extinct Turns Up in Fish Market

When scouting for extremely rare species probably the last place you’d think to check would be “the store.” And yet it was at a store of sorts–a public fish market in Kuwait to be exact–where marine researchers rediscovered the smoothtooth blacktip shark (Carcharhinus leiodon) in 2008.

Ultrasound Ocean Noises Pose Risk to Marine Life

by Michael Stocker Noise pollution has now become one of the common themes of human-generated impacts on the ocean.

Bull Shark Catch in Maryland Highlights Nearness of Species to Shore

They’re baaaaack! Not that they were ever gone; they’ve just kept a low profile.
