500-million-year-old #fossil reveals how #starfish got their shape https://phys.org/news/2025-06-million-year-fossil-reveals-starfish.html
A new #Cambrian stem-group echinoderm reveals the #evolution of the anteroposterior axis: Stephanie Woodgate et al. https://www.cell.com/current-biology/fulltext/S0960-9822(25)00681-5
"The fossil, #Atlascystis acantha, is the oldest known #echinoderm with a bilateral body plan. It bridges the evolutionary gap between the closest living relatives of #echinoderms, all of which have bilateral symmetry, and the familiar five-armed forms alive today."

Today I started laying the groundwork for a big #pastel artwork, featuring 12 #SeaStar species. I think I made one of these charts in primary school for the last time! So much fun 💫

Earlier this week a student told me how some sea anemones can swim away when attacked by sea stars.
They showed me this video of it happening. It's excellent.
Keep it in mind if you see something creeping up slowly towards you.

Check out this exceptional sea cucumber from Singapore. Real nature can be more bizarre than fiction.
The photograph is by @budak, well worth a follow on both Mastodon and Flickr. They find and photograph amazing animals.

It’s not every day that you see the phrase “Gummy squirrel with parasitic snail attached”, yet, here it is, on #RadioNewZealand.
Turns out a “gummy squirrel” is “a weird sea cucumber with a large sail-like extension” and this one was found on a recent deep sea expedition to the Bounty Trough “one of the world’s least explored deep-ocean ecosystems”.
It’s an interesting article about lots of new discoveries.

I finally realized @KateShaw has a new episode out, and it's on an antarctic starfish:

The cool #evodevo paper everyone is talking about: Molecular evidence of anteroposterior patterning in adult echinoderms
"This finding suggests that from the perspective of ectoderm patterning, echinoderms are mostly head-like animals and provides a developmental rationale for the re-evaluation of the events that led to the evolution of the derived adult body plan of echinoderms."
