Glob-glob! Absolutely magical sea anemone larva (about 7 mm) from The Lombok Strait, Indonesia 🇮🇩
Tracing clonality, we find that PLSTC LSCs occupy a variety of stable, self-renewing states within the same well. So, this apparent continuum is actually made of thousands of clonal "constellations"!!!! Using @adameykolab.bsky.social super cool tool scLiTr, we can group these into 5 fate clusters.
Chaos in my dish: a hydrozoan jellyfish Leuckartiara octona tries to squeeze between bipinnaria larvae of Luidia sarsii starfish. The North Sea, Skagerrak ✨🌊🔬 These animals are about 7 mm in length - quite large as compared to what I typically show here.
The red-chested sea cucumber, Trachythyone insolens, from Cape Town, South Africa 🇿🇦.
Holothurians (sea cucumbers) are primarily deposit or suspension feeders that use specialized, mucus-covered oral tentacles to trap food particles, such as organic detritus, from the seabed or water column.

Here is the new meditative film about zooplankton and other cute animals from Okinawa. If you feel a need to calm down - just start watching it: youtu.be/JtwwoEzW3vU?...
Finally, I went to the forest not-so-nearby
We start with an invited talk Clonal Reconstruction at Single Cell Level Helps to Decipher Embryonic Development by Igor Adameyko @adameykolab.bsky.social, Karolinska Institute @ki.se & Medical University of Vienna @meduniwien.ac.at
Gonionemus vertens is a hydrozoan jellyfish with a beautiful medusa stage and tiny modest polyps. I collected and filmed a bunch of them in Skagerrak, North Sea. These are quite dangerous jellies - one sting can send a person into hospital.

I worked a bit longer on my pink nudibranch video collection resulting from my Okinawa trip (visiting colleagues at OIST). Now the full video is on youtube: youtu.be/-YF9AQxVYS0?...
A Cyerce kikutarobabai nudibranch from Okinawa. This one is very tiny - 3 mm long. I found it bouncing in the waves being torn from the reef by the water power. It was flying like a pink dot among the muddy water with debris. I did not expect much before I brought it under the microscope.
This is a really nice position with a great mentor. Highly recommended. Rush.

Thanks 😁
Parley.tv made a story about my work on plankton biodiversity: parley.tv/journal/igor...
One of the best parts of Gordon Conferences in Italy.
It was wise, i agree 😁🙌
Another video of our feeding experiment using fluorescent beads and bryozoan colonies (Membraniopora sp.). 💫
Most of these animals are adults, with few larvae among them. Adult forms: copepods (monstrilloids) and cumaceans, for example. Not sure how we shall consider polychaete epitoke brooding pink eggs - also as adults i suppose.. However, shrimp zoea are larval.
They are eggs. Some are already fertilized.
Yes, it is a starfish baby. Another one is a hydrozoan jellyfish
Mediterranean zooplankton from Pula.
This is what is currently missing: GFP fluorescence of the GFP-beta-catenin knock-in embryos showing maternal GFP-b-cat in the vegetal half of the embryo and the onset of gastrulation at the animal pole.
