Neural crest biologist interested in broad and deep questions about clockworks of nature.
The kissing of sea slugs. Reminds me of Gustav Klimt paintings. Elysia viridis, commonly known as the solar-powered sea slug or sap-sucking slug, is uniquely distinguished by its rare ability to steal plant-like cellular machinery from the algae it eats and use it to perform photosynthesis.
Two tiny hydrozoan jellies talking to each other (Melicertum octocostatum, 5 mm). Kattegat, The North Sea.
What a surprise - a tiny, 1 mm long planktonic bunny 🐰. This a chaetopterus worm larva. Kattegat, The North Sea 🌊 🔬 Chaetopterus, known as the parchment worm, is a highly specialized marine polychaete living the adult life inside self-constructed, papery tubes that resemble parchment paper.
Gonionemus vertens, commonly known as the clinging jellyfish (or klängmedusa in Swedish), is a small, highly toxic hydrozoan jellyfish native to the coastal regions of the North Pacific Ocean. Despite its tiny size, its potent sting poses risks to swimmers and divers.
Cladoceran from Kattegat, The North Sea. It took me really long time to get the lights right - these creatures are super transparent.
This pulsing orb is the advanced 1 mm larva of a sea angel ✨🌊🔬. Kattegat, The North Sea. Sea angels are my fav mollusks, and I’ve always been dreaming about seeing an advanced larva.
Rhopilema esculentum, commonly known as the flame jellyfish or Bizen kurage, is a species of edible jellyfish native to the warm temperate waters of the Pacific Ocean. Aquarium of Paris. ✨🌊
Glob-glob! Absolutely magical sea anemone larva (about 7 mm) from The Lombok Strait, Indonesia 🇮🇩
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.
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.
Another video of our feeding experiment using fluorescent beads and bryozoan colonies (Membraniopora sp.). 💫
Feeding bryozoans. The experiment with fluorescent beads. Helgoland, North Sea 🌊
Another try to post a video: starfish larva, 1 mm long. This is a brachiolaria stage.
Pretty amazing seed pods of Drooping star of Bethlehem (Ornithogallum nutans L.)
What is new in the neural crest domain? Which neural crest-related studies do you find fun and exciting? Let’s have an interesting discussion. I feel like I want to go back to look into the pigmentation patterns and evolution of multipotency.
Our sweet cubozoan Tripedalia. Their rhopalia contain image-forming eyes and are bilaterally-symmetrical.
We have different hobby projects in the lab, and some of them focus on cnidarians. Here i filmed Cotylorhiza tuberculata jellyfish 🤩
(16) Some perturbed clones showed completely novel behavior (in the case of Ptch1 knock-out) or distortion of already existing clonal programs (Fgfr1, Fzd2, and other knock-outs) — it wasn't possible to distinguish these cases without clonal information.
