Fire Urchin (Asthenosoma varium), Anilao. These are always worth checking for commensal shrimp and crabs, and they often get all the attention, but urchins are also pretty cool in their own right. #MarineLife #echinoderms #Invertebrates 🌿

🧠🦔 Research from scientists in #Italy and #Germany shows sea urchins aren't "primitive" but have complex "all-body brain" nervous systems distributed throughout their #anatomy.
Analyses revealed hundreds of neuron types producing neurotransmitters like dopamine and serotonin, plus light-sensitive cells covering their bodies that function like distributed vision systems despite having no eyes.

"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."

Does anyone have a good reference for how #echinoderms resurface and/or recognize the #seafloor in their #habitat? It's something I've observed, but I can't seem to find any reference describing or quantifying it.
(I've looked at the bioturbation literature; it's not what I'm looking for) -
Zoology hot take:
Brittle stars are just starfish (sea stars) which have made their way through the Amigara Fault.

Fossil shows #starfish relative engaged in clonal fragmentation 150 million years ago https://phys.org/news/2024-05-fossil-germany-starfish-engaged-clonal.html
#Fossil evidence for the ancient link between clonal fragmentation, six-fold symmetry and an epizoic lifestyle in asterozoan #echinoderms https://royalsocietypublishing.org/doi/10.1098/rspb.2023.2832
"many species of #BrittleStars are capable of reproducing by splitting off parts of their body, both of which then regenerate, resulting in two distinct clonal creatures, a process known as clonal fragmentation"

Holy Glowing #DeepSea Cucumbers! https://deepseanews.com/2024/01/holy-glowing-sea-cucumbers/
Glowing sea cucumbers: Bioluminescence in the Holothuroidea https://www.sciencedirect.com/science/article/abs/pii/B9780323953771000035
"In this #luminescent tapestry, #SeaCucumbers emerge as unexpected stars. While we might not associate these #echinoderms with #bioluminescence, they contribute significantly to the underwater light show... Venture to the depths of one kilometer, and you’ll find that luminous sea cucumbers constitute an astonishing 99% of all sea cucumbers."

Advanced imaging reveals the last bite of a 465-million-year-old trilobite https://phys.org/news/2023-09-advanced-imaging-reveals-million-year-old-trilobite.html
Uniquely preserved gut contents illuminate #trilobite #palaeophysiology https://www.nature.com/articles/s41586-023-06567-7
"The digestive tract of the trilobite #Bohemolichas incola was tightly packed with #calcareous #shells and their fragments that belonged to marine #invertebrates such as #ostracods, #bivalves and #echinoderms, some of them identifiable to the species level."

Hiya Mastodon,
Re- #Introduction time! I'm Ash, a stop motion animator of wildlife and paleontologist.
In the last year I moved from Australia to France and to Mastodon from my ex Twitter handle @aela_wild.
With the move I renamed my business to StudioWild. So far it's a better fit :)
Now that I'm set up, I post about natural history and share my mixed media art. I'm looking forward to getting to know my new landscape and all the weird wild animals and places in between.
If you're inclined, my animations live on YouTube https://www.youtube.com/@studio_wild
