A thing that Biden could do to immediately increase his popularity is to immediately require that all tuna and swordfish fisheries use circle hooks and not J hooks. This is something I care about and therefore I assume it’s wildly politically popular. (This is what some of you sound like).

It has been pointed out that some of the obviously-nonsense claims made on Shark Week by scientists violate my professional society’s code of professional ethics. Interesting. Looking into this.

Several people have been asking me for my suggestions of what Shark Week shows to watch and which to avoid. I’m not doing that anymore. 1) They stopped giving media preview material so all I have is the episode titles and 1-sentence descriptions 2) Most of them are pretty bad

I’ve now observed a Florida news channel say something to the effect of “I’ve never heard of so many sharks near shore” every year for the past 8 years, at least. You have heard of it my dude. From yourself, last year. Enough with the fearmongering.

Sometime in June, Twitter discontinued free analytics. Several of my science communication consulting clients still use Twitter as a (smaller and shrinking) part of their communications portfolio, but they need data to see who they’re reaching. And they won’t pay Twitter for that.

Today in Miami, 15 of my social media followers from around the country will be joining me for a day of shark research. Their donations help to support the lab’s efforts to bring Miami public school students out on future trips. Wish us luck!

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.

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!

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!

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.

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

Absolutely. The smallest sharks are about the size of your forearm. Even big sharks are eaten by crocodiles or orcas.
