I am delighted to share our paper, published today in @nature, on baleen whale prey consumption and what it means for marine ecosystems. nature.com/articles/s4158… A thread 1/n

Do any of my talented sharktists know where I could find a cool bull/shark/bullshark icon or graphic set to use for a strictly personal project / general family crest? Meg's a Taurus & I'm a shark scientist. And my hot sauce labels need some pizzazz! Thx in advance :)

Just published, cool study with friends: China farms >80% of the world's oysters. Satellite analysis & questionnaires show this causes 961 tons of plastic pollution a year in just 1 area. Hopefully a 1st step to awareness & management. authors.elsevier.com/a/1f2xS9pi-WNyu

Accelerometry classified young lemon #sharks as resting/swimming/foraging: Rest nearshore at high tide, move offshore, increase swimming, foraging peaks at low tide & dusk. Once older/larger/safer from predation, home range & foraging increases. authors.elsevier.com/c/1jA4EmjM6Fgw

If you dove into the ocean in the 1800s, you would have been treated to a complex symphony of sound: raindrops falling, seals moaning, staccato snapping of shrimp, undersea vents bubbling & love songs of humpback whales. Today the sea sounds different. science.org/doi/10.1126/sc…

Fascinating new paper whereby genome analysis reveals three distinct lineages of the great white shark: 🦈 White shark populations are divided into three discrete lineages globally 🦈 Lineages diverged 100,000–200,000 years ago, during sea level lows

Great white sharks visit the Bahamas! Sharks acoustically tagged in Cape Cod/NE USA visit deep waters off Andros at night in spring tinyurl.com/3rnzh4sv. Cheers to great team & reviewers!

Faster than disaster! Interesting work from Spain+Stanford: a nuclear reactor disaster near Barcelona shouldn't radioactively contaminate Atlantic bluefin tuna above safe levels because they move through the region too quickly t.ly/FRmix
