Later this year I’ll be joining the Comparative Embryology of Marine Invertebrates (CEMI) course as an instructor. It will be held from November 25th to December 8th, 2026, at CEBIMar–USP, São Sebastião, Brazil. CEBIMar is where I did my master’s thesis about the embryonic development of a sea biscuit and where the Oceano and Cifonauta […]

The winners of this year’s Nikon Small World in Motion are out, and my favorite is the 5th place entry, A newborn sea urchin walking along the seabed by Alvaro Migotto: It’s adorable to see these newly metamorphosed echinoderms and their long and chubby tube feet learning how to walk. This scene reminded me of […]
The other day I stumbled upon this passage in the Wikipedia page of Piseinotecus, a genus of beautiful nudibranch sea slugs: The name Piseinotecus comes from the Portuguese sentence “pisei no Teco” (I stepped onto Teco). Teco was the name of a dog of the zoologists Ernst Marcus and Eveline Du Bois-Reymond Marcus. While they […]

The Platynereis genome paper is out 🎉 Mutemi KN, Simakov O, Pan L, Santangeli L, Null RW, Handberg-Thorsager M, Vellutini BC, Peterson KJ, Fromm B, Larsson T, Savage E, Lopez MO, Hercog R, Provaznik J, Ordoñez-Rueda D, Azevedo N, Gazave E, Vervoort M, Tomancak P, Tan W, Winkler S, Benes V, Hui J, Helm C, […]
The other day I was looking for some information about Brazilian velvet worms and found this website: onychophora.com. The gallery of photos is impressive!
We generated a transcriptome from developmental stages of the annelid Platynereis dumerilii using the Iso-Seq method from PacBio, which outputs full-length transcripts and resolved isoforms. The dataset is now available on Zenodo: Vellutini, B. C., Handberg-Thorsager, M. & Tomancak, P. (2024). Platynereis dumerilii full-length transcriptome of developmental stages. doi:10.5281/zenodo.14250773 The transcriptome was used for the […]

Veritas Magnus Vis Microscopia is a free public art exhibition curated by SubtleFlux (Shae Nadine) that is showcasing microscopy images and videos in downtown Chicago, USA. In magnifying these concealed worlds, we aim to unveil the inherent beauty and undeniable truths that underscore our collective responsibility as stewards of Earth. From Veritas Magnus Vis Microscopia‘s […]
I never imagined that one day I’d be looking at the embryology of fleas… But here I am.
Marine invertebrate larvae are incredibly diverse. They have all sorts of unique features—tentacles, lobes, bands of cilia, shells, bristle hairs, etc.—which they use to capture food, to swim, and to protect themselves from predators. Their morphology is functional. But also beautiful. That’s why I was excited to discover these larval stickers made by Dexter Davis: […]
