Our paper on convergent evolution of land crabs is out in its final final form. The journal didn't pick my image as the cover, so I'm sharing it here because it must be seen!

Circular timetree of crabs with pie slices colored by superfamily (Figure 2 in the paper). Simplified version with no text/labels. Line drawings of crabs arranged around the perimeter like a zodiac, with colors matching the superfamily pie slice.

I think he might be on the Appalachian trail or something like that. No crabs, but there are crayfish!

I'm on the BBC talking about (how we won't be) evolving into crabs 🧪🦀

Also features Matt Wills (my academic older brother) and Ned Suesat-Williams (of the crab museum!). Unfortunately they were in London and I on zoom, so there was no time to tell Ned to join here

World octopus day, you say? Very well, then... here is an octopus (possibly a male argonaut). No clue what the jellyfish is. The jellyfish is swimming down to try and get away from the bright flashing lights.

A jellyfish, upside down because it's swimming downwards. On top of its bell is an octopus; it is translucent/white with some visible brown organs.

Here's some large cuttlefish/CUTElfish for this wonderful day!
Two quite large (person sized) cuttlefish jetting over a beautiful reef. You can tell how big they are as divers are in the background. The colors are dancing grey and dark mottling on the one in front, dark striations on the one behind who has tentacles extended. Photo by Andrea Ramos

Happy world squid and cuttlefish day!!

Text your friend a squid fact. Watch a video of a cuttlefish doing something cute.
Doodle a squid and then show it to me.

The world is cruel but squid are good.

What you hear is almost exactly what we discussed! (We guests didn't hear the intro until it was made public, I guess it was recorded separately)

Stanford affiliation is the BBC's typo...

But UCSB is real, I'm joining their Marine Science Institute! I never announced it because my job there is soft money (depends on grants for salary) so I don't know when/if I can move to CA.

Replies off as this doesn't invite political commentary

I have not heard Beverly said out loud somehow? Weird because I've passed through it on the commuter rail. How do you say it?
