If you think Jaws is scary for not really showing the shark, you should check out spielberg's other films. they don't show the shark at all

Huh. I got a Google scholar alert that a paper wildly outside of my field cited one of my papers. But they didn’t. They cited White et al 2021, not Whitenack et al 2021. Then the wrong reference got added.

A great day of shark tagging in Miami- we caught 4 sharks of 2 species, blacktip and blacknose!

Thresher sharks use the upper lobe of their caudal fin, which can be as long as the rest of the shark, as a whip to stun prey fishes!
What's with the super long upper tails some sharks have?

Made it to Miami! I’ll be out on the R/V Garvin tagging sharks the next 3 days, including taking out social media followers and friends who donated to support a future trip for Miami public school students.

In the early Twitter days science types would show up and post when they had a new paper. Wonderful! But real talk y'all: papers take ages to write. So, post about other people's stuff! You read a paper and it was cool! Or you had a question! Or it tied to this other thing! Tag the authors!
Science folks, one thing about bluesky is there's way less 2 way interaction between people, especially on science posts, than there was on old Twitter. I'm not sure why that is, but it's something I'm keen to encourage. I'd love to hear your thoughts 🧪

That's pretty darn cool! Thanks for answering my question! They are such amazing animals!

0 sharks ever have been killed to supply $5 bags of shark teeth at beachside stores. Sharks lose teeth constantly their whole lives. You can find them on beaches.
I've seen bags of shark teeth for sale and was intrigued. They said they collect them, as sharks constantly lose them. Is that true? Is the shark tooth trade harming them? (Wondering whether to buy them for a craft project, as I'd like to avoid plastic)

Yooo that's so interesting, thank you!

Hammerhead cephalofoils provide extra surface area for the electrosensory system, you’ll often see them moving their head back and forth across the sand like someone with a metal detector at the beach. Also useful for pinning flat prey like rays down so they can be munched
Are we any closer to understanding why hammerhead sharks are shaped the way they are?
