So, everytime we see a glass sponge or hexactinellid on #Okeanos we bring up how amazing the skeleton is-made of GLASS (silicon dioxide) that transmits light better than anything human made-here's what it looks like (from a euplectellid) #spongeThursday

In my ongoing efforts to retain a little sanity, I take refuge in #SpongeThursday and the #fossil record. This is Astraeospongium meniscum - a Silurian (~425 MYA) heteractinellid from Tennessee. In the wonderful #Invertebrate #Palaeontology collections of @romtoronto.bsky.social

It looks like a flower-but is an animal-a carnivorous sponge (Cladorhizidae)!! Whereas most sponges just absorb nutrients as they are carried by, these will devour small crustaceans on those spines! pretty good for something without proper tissue! #spongeThursday #Okeanos 2017
flower-like animal with the "head" projecting numerous spines and a thin, narrow stalk

Ha ha. A glass? sponge that reminds me of Quark from #deepspace9 from Beethoven Ridge at 2310 m #Okeanos North Pacific #spongeThursday Lasers are about 4 inches apart so that's a big one!

Looks like disease is affecting several sponge species in the USVI. Check out the lesions on this Agelas and Aplysina near St. Croix. Anyone else picked up on this? #spongethursday

Sponges are important members of the deep-sea community. Sometimes they are food for other animals such as this goniasterid sea star, either Ceramaster or Bathyceramaster! #okeanos on Salmon Bank in North Pacific, 2016 #spongeThursday #echinoday

More sponges of Cape Palos: Yellow Boring sponge (Cliona celata), Phorbas topsenti, ?Ircinia variabilis & is the dun, leathery, suspended, flapping life form even a sponge?

Sponge spicules, composed of silica, in thin section. The ornate end structures are used to attach one spicule to another to form an internal skeleton that is flexible enough to sway and bend in flowing water (from Three Kings Islands seafloor, northernmost NZ). ⚒️🧪🌊
