#Ophiuroidea
Sea star pile-up. ⭐️⁠
⁠
These brittle stars are mud-loving animals, often found crawling across the muddy plains of the seafloor. This group of sea stars, known as Ophiuroidea, boasts a diverse number of species—more than 2,000 different species!

Some abyssal brittle stars (Ophiuroidea) drop limbs to escape and then regrow them later. Survival isn’t about overpowering a threat. It’s about refusing to let violence be the end of the story.

The scientific name (Ophiuroidea) does come from the Greek for snake (ὄφῐς, ophis).

Another from our 2013 research cruise....(LMG13-12) along the Western Antarctic Peninsula. I BELIEVE this is Gorganocephalus chilensis (Ophiuroidea). #antarctica 🧪🌎🦑🇦🇶

BIG BLACK BRITTLE STARS! Ophiomaza (feather star associate) and Ophiocoma! Both sizeable animals maybe 2 to 3 inches in diameter! The ridged one from central Pacific tropics, the other from Eastern tropics! #echinoday #ophiuroidea

Die Gorgonen- oder Medusenhäupter (Gorgonocephalidae) sind auf Planktonfang spezialisierte Schlangensterne (Ophiuroidea), deren Arme stark verzweigt sind. Große Gorgonenhäupter können einen Durchmesser von 1,5 Meter haben, mit Armlängen von 70 Zentimeter. #verrückteTiere

Nature research paper: Spatiotemporal faunal connectivity across global sea floors

go.nature.com/3H3HPbf
Spatiotemporal faunal connectivity across global sea floors - Nature
We analyse a global dataset of genomic DNA sequences for Ophiuroidea to gain an understanding of phylogenetic divergence and biotic movement across oceans, finding phylogentically divergent faunas at shelf depths but greater connectivity of species at deep-sea depths.

Sea star fans, wake up — it’s the third week of our ID-a-thon, and we’re sorting echinoderms. Visit iNaturalist to learn more: tr.ee/identifyweek3 ⭐💫

When we hear that Museums Victoria @museumsvictoria led the world-first study mapping the distribution of Brittle Stars (𝘖𝘱𝘩𝘪𝘶𝘳𝘰𝘪𝘥𝘦𝘢) it seems like a good time to celebrate Ernst Haeckel’s “Kunstformen der Natur” which truly elevates #sciart to #highart!

I'm thrilled to present our latest paper about the trophic ecology and behavior of sea stars (Asteroidea) and brittle stars (Ophiuroidea) from the Clarion-Clipperton Fracture Zone. doi.org/10.1016/j.ds... It was a great collaboration with a team from 🇪🇸🇳🇱🇩🇪🇵🇹 and 🇦🇹 (incl. @bokamero.bsky.social). #SciArt

Ormstjärnor (Ophiuroidea) ligger oftast på botten (vissa är nergrävda och håller bara sina armar ovanför botten för att få tag i mat).

Men ibland reser ormstjärnor sig upp på sina armar. Detta kan vara ett synkat beteende när ägg & spermier släpps ut.

d'un anus !

Les étoiles de mer ont une bouche d'un côté et un anus de l'autre.

Les ophiuroidea n'ont qu'un seul orifice pour les 2 fonctions (on considère que c'est une bouche et qu'ils régurgitent après digestion).

Al contrario de lo que cree mucha gente, no es una Estrella de Mar, clase Asteroidea, pertenece a la clase de la Ofiuras, Ophiuroidea. Aunque eso sí, ambos son parientes cercanos, ya que pertenecen al grupo de los Equinodermos.

Babe don't forget, even previously permitted readers may need the special aquatic monster-fucker specialty! However, good news, active diver certification is NOT required, thanks to our helpful partners from the class Ophiuroidea 😌

Gustav Paulay: “It’s essential to zoom out. When focusing on something so little, you can lose context in which you operate in. And often the context changes what you perceive to be going on.” These efforts often spark unexpected collaborations.
