Besides the welcome beds of Lesser Water-Parsnip (Berula erecta) growing on the clean sands of the River Nar, there were also some strands of Common Mare's Tail (Hippuris vulgaris), and beneath rocks etc, freshwater sponges (Spongillidae). #SpongeThursday #Wildflowerhour #rivers #flower #nature. 7/9

From #okeanos MANY years ago off the Santa Barbara coast, 2011 or so? Heterochone calyx, called informally the "goiter sponge" but now the "fingered goblet sponge" a stunning beast! quite large! 2m across sometimes! #spongethursday more on these www.mbari.org/animal/finge...

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
A shot of a tag from old school bath sponges! Back in the day before plastic sponges, they harvested ACTUAL hand-sized sponges (animals) for your bathing/scrubbing needs! Farmed on strings,etc. then sold in drug stores for your sundry needs! These are STILL sold as "organic sponges" #spongeThursday
