Fun fact: Apache jumping spiders (Phidippus apacheanus) are completely harmless, but evolved to mimic velvet ants from the genus Dasymutilla so predators wouldn't mess with them.

I'm not joking, this is not me being cleaver, I genuinely do not know: Is this real, or is this a parody? I can't tell anymore. Someone help.

Omg you make it sound like it’s been ages πŸ€£πŸ˜‚πŸ€£ we only got the final piece (genetics) last fall. It has been a long time coming and I’m glad it’s in the world now.

There's something that feels a bit dead about the world right now, but tens of thousands of people just came together to help us solve a 100 year old mystery about a little blue jelly, and I find that heartbreakingly hopeful:

In our last thread, we left the jelly-enjoyers of Bluesky with a cliff hanger ending, in what one eager onlooker described as soap opera science 😜 ... wait no more, we are back! Grab your popcorn shrimp and come with us on a journey spanning more than...

"If you just look at the x-axis right here, yes, see this axis?? Ok, so you'll notice how the value of PCA1 goes from -5 to positive 5, and how......NO YOU HAVE TO LOOK AT THE AXIS!!"

was randomly browsing r/megalophobia earlier only to see an image of stygiomedusa with a snorkeler at the surface, which is bonkers since it's a deep sea jelly. πŸ¦‘πŸ§ͺ

after a little digging, it came from this paper: doi.org/10.1590/S198...

Bolinopsis microptera comb jelly (ctenophore) swimming horizonally.

Bolinopsis microptera comb jelly (ctenophore) swimming horizonally.

Let's do another #ctenophore survey.
You are scuba divining and see this lobate comb jelly cruising in search of prey. Is it swimming to the LEFT or RIGHT?

A spherical comb jelly floating against a dark background, with its tentacles deployed, tentilla (side branches) fanned out. There is a number 1 above the body and number 2 below the body. Photo by S. Haddock taken around 1990.

For CTENOPHORE DAY, a little survey:
Which end of this fishing Pleurobrachia is the mouth on? Please just "vote" in the comments β€” no definitive answers. πŸ¦‘πŸ§ͺ🌊

P.S. this is one of my earliest #ctenophore photos, shot on film in a home-built kreisel.

P.P.S. Legit data-gathering for a future paper.

Ok folks, time to help with actual science while scrolling social media!

Marine biologist Dr. Steve Haddock is conducting a study on public perception of this critter down below. He needs replies!

Please go talk to Steve and re-skeet far and wide!

Hey author friends! Please help! I do freelance writing, and I’m trying to find my DC pro and semi-pro writer friends.

How do I find them? Are there Bluesky starter packs, meetup group, professional societies?

How do writers find each other?
