Tiger sharks have long had a reputation for being opportunistic feeders that aren’t picky about what they end up eating. Everything from sea turtles to tarpon to license plates seems to be on the menu for this predator. A new study found a surprising favorite snack for tigers — birds. Not just any birds like […]
Killer Whales vs. Great Whites: Who is king of the ocean?
In the ocean, both the great white shark (Carcharodon carcharias) and the killer whale or orca (Orcinus orca) are fearsome top predators. But of the two massive animals, the killer whale may be the more formidable one, a new study has found. Salvador Jorgensen, a marine ecologist at the Monterey Bay Aquarium in California, and his colleagues […]
New study reveals great white sharks’ fear of killer whales
There is always a bigger fish. A new study by the Monterey Bay Aquarium found that even great white sharks, one of the most formidable predators in the ocean, have something to fear. According to the research, which also included research partners from Stanford University, Point Blue Conservation Science and Montana State University and published […]
Citizen scientists identify sand tiger aggregation site in North Carolina
The photos, many of which were submitted as part of the SpotAShark USA program through the North Carolina Aquariums, dated back to 2007.
White sharks can tolerate toxic levels of heavy metal
A recent study by researchers from University of Miami Rosenstiel School of Marine and Atmospheric Science found that great white sharks were able to tolerate high levels of heavy metals that would be considered toxic to other marine animals. Using blood samples taken from great whites off the coast of South Africa, the researchers found […]
VIDEO: Watch as great white shark stalks prey in kelp forest
A new study found that some great white sharks in South Africa may enter kelp beds to hunt for seals, a behavior that had rarely been observed. Researchers at the Monterey Bay Aquarium have used satellite tracking tags equipped with underwater cameras to observe these large predators in their natural environment by providing a “shark’s-eye-view” of […]
Humans may soon regrow teeth just like a shark
Sharks are the ultimate predators of the aquatic realm thanks to one character in particular – teeth. Not only are shark’s teeth razor sharp but they are also constantly regrown throughout life, gradually replaced like a conveyor belt of rows of teeth, and not just when they are worn down or fall out. This is […]
Cartilage skeletons an evolutionary adaptation for sharks
Sharks are one of the oldest and least changed of all the living back-boned jawed creatures. But because their skeletons are made of cartilage much of their early fossil record is poor. Cartilage is a rubbery tissue that forms the framework for bones to ossify (harden) upon. It’s why babies have rubbery legs when they […]
New species of lantern shark discovered
Nearly three decades after it was first found, a specimen of deep-water, bioluminescent shark has been named a distinct species. University of Rhode Island shark researcher Bradley Wetherbee, who was among the researchers that originally studied the specimens that were inadvertently caught in the Northwestern Hawaiian Islands in 1988, named the new species Etmopterus lailae […]
New study shows more genetic data on sharks needed
The headlines are eye-catching: Scientists have sequenced the genome of white sharks. Or the bamboo lemur, or the golden eagle. But why spend so much time and money figuring out the DNA makeup of different species? I am an evolutionary biologist at the Florida Program for Shark Research. Our research focuses on understanding how modern […]
