This is one my favorite images I’ve ever taken of a freshwater sponge
The depth-coded image (stained for F-actin) beautifully shows the static nature of the choanoderm and the extremely dynamic nature of migratory cells along and around the outer epithelia :)

Took some beauty pictures this past week of choanoderm in the freshwater sponge, Ephydatia muelleri :)
These choanocyte chambers facilitate filter feeding and direct phagocytosis of organic matter and microbes

Well this is fun :)
Looks like there’s a planarian hanging out in this sponge’s osculum

Took a Timelapse to commemorate this #sponge being 6 months old!
Alas, an unexpected bout of shrimp cannibalism has stolen the show…

Best part about water-change day is being able to watch photosynthesis in real time, when the water is no longer saturated in O2 🙂🤓🌿🌱

I wonder if I will ever fail to be blown away (pun intended) by the speed at which sponges move water through their tissues…
…the flow being generated by countless, coordinated beats of flagella ??! 🤯🤯🤯
I love them ❤️🧽

A timelapse of (~2hrs) of feeding sponges a reddish slurry of phytoplankton in suspension
You’ll notice they change from green to brownish as they take up this food
(NOTE: shrimps and snail are *not* from the sponges’ natural habitat)

A fun lil side project this year has been trying to sustain sponges in lab long-term
Turns out the difficult-to-replicate idea of a community-driven system sourced primarily from sponges’ natural habitat—from grasses and microbes to worms and isopods—did the trick :)
