But this gradual posterior-to-anterior "unzipping" effect amazed me !

Excited to see the egg sac with eggs that already have eyes developing.

I created a collection of 6 short video clips. I plan to ask my students whether they were created with AI. https://wakelet.com/wake/OB_4iRd7-wgaqRie96nt0 THANKS!25 Mar 2026 17:47 +0000at://did:plc:qbdarcarqyfpnto7n62whjyq/app.bsky.feed.post/3mhvnigqlic2bhttps://bsky.app/profile/evoexplorer.bsky.social/post/3mdj6nnokq22oI just enjoyed seeing this Sun Animalcule (aka Heliozoan) in a sample, took a photo of it, and digitally painted it.

Aeolosoma, Paramecium, Rotifers, and Stentor Can you spot any species I missed? #microscope #naturephotography #biology #iteachbiology #edusky10 May 2025 14:56 +0000at://did:plc:qbdarcarqyfpnto7n62whjyq/app.bsky.feed.post/3lot77ai7wc2ahttps://bsky.app/profile/evoexplorer.bsky.social/post/3lxpj2eavnk2rIt's always nice when you see a nauplius that isn't hell-bent on zooming everywhere. LOL *For my non-bio friends, a nauplius is a larval form of a crustacean. I suspect this one belongs to the genus Cyclops - a copepod. #microscopy #nature #biology #edusky #iteachbiology #science31 Aug 2025 16:29 +0000at://did:plc:qbdarcarqyfpnto7n62whjyq/app.bsky.feed.post/3lxpj2eavnk2rhttps://bsky.app/profile/evoexplorer.bsky.social/post/3mgi67vgmcs2jWhile pretty common in samples from puddles & birdbaths, I never tire of the antics of Ostracods - the hyperactive #crustaceans who also bear the nickname "Seed Shrimp" - they have a fossil history going back over 570 million years!

I was hoping to see the Paramecium get sealed into a vacuole, but instead it finally managed to escape! My students have nicknamed Bursaria "Micro Roomba."
