Starfish don't have hands but they got feet :)

For today's #inkyDays drawing, I felt like drawing some dancing starfish. So I did.

Here's an in-progress shot.

I also finished a floral-network piece, on watercolor paper. It's really nice to have more time for drawing again.

I've shared these in posts for my supporters on Patreon and Ko-fi (all levels):

Marine mystery solved: Bacteria identified as the cause of sea star wasting disease, a breakthrough for ocean ecosystems. #SeaStars #MarineLife #Ocean

https://www.vox.com/science/421961/sea-star-wasting-disease-cause-new-research

Discovery of #SeaStarWastingDisease cause sheds light on #kelp forest collapse and recovery https://phys.org/news/2025-07-discovery-sea-star-disease-kelp.html

"This comes more than a decade after the start of the marine epidemic that has killed billions of #SeaStars... The 4-year investigation eventually pinpointed the microbial culprit: a strain of the bacterium #Vibrio pectenicida... The loss of #SunflowerSeaStars, which support #KelpForests by feeding on kelp-eating #SeaUrchins, has had widespread and lasting effects on ecosystems"

"[I]n August 2025, after another year-and-a-half of work confirming and reviewing their findings, Gehman and her team have published a peer-reviewed study in the journal Nature Ecology & Evolution identifying Vibrio pectenicida, a saltwater-loving bacterium that works its way into sea star fluids, as the likely “dominant pathogen responsible for sea star wasting disease.” Gehman’s team has tracked down the killer."

Belinda the surprisingly busy sea sponge takes a whole day to sneeze https://www.cbc.ca/radio/asithappens/belinda-sea-sponge-sneezing-1.7426170

"researchers have used 4 years of time-lapse footage from the sea floor of #BritishColumbia to paint a picture of the daily life of a busy #sponge... They learned Belinda has both a daily and an annual routine, changing shape, size and colour with changing seasons. Rarely lonely, Belinda receives visitors from a diverse array of ocean critters, including #snails, #crabs, #SeaStars, & #anemones"

"Not so long ago, you could count on #pycnopodia to devour #PurpleUrchins and keep them from eating too much #kelp. A decade ago, the mysterious wasting disease began plaguing #SeaStars, right around the time that a #MarineHeatWave struck... In the absence of their primary predator, urchin populations exploded. Since then they have mown across the sea floor unhindered, leaving urchin barrens where #KelpForests once flourished."

Phylogenetic and taxonomic revisions of Jurassic #SeaStars support a delayed evolutionary origin of the Asteriidae https://peerj.com/articles/18169/

"This research reassesses 6 well-preserved #Jurassic sea star #fossils and reveals that none of these belong to modern families like Asteriidae... Asteriidae likely evolved during the Late #Cretaceous, up to 100 million of years after the species analyzed here"

I was just wondering why I never see starfish in LA tide pools any more -- they were everywhere when I was a kid. It turns out that the population was devastated in 2013-4 by sea star wasting syndrome, a poorly understood phenomenon that can basically dissolve a sea star in just a few days.

Some dancing starfish for today's #inkyDays drawing. With my recovery from surgery, I can't really dance yet, but I'm dancing on the inside.

Here's an in-progress shot.

And that's a wrap for this month's daily drawings. In-progress and complete drawings for this month are now all posted for my supporters on patreon and kofi in this month's #inkyDays posts:

"scientists observed 160 species on the Salas y Gómez Ridge that had not yet been known in the region and suspect that at least 50 of them are new to science. These are #squid, #fish, #corals, #mollusks, #SeaStars, glass #sponges, #SeaUrchins, crabs, and squat #lobsters, amongst others. They set a record for sighting the deepest-known #photosynthesis-dependent animal in the world: #Leptoseris, a wrinkle #coral."
