Is adulthood just an illusion? The impact of size and ontogeny on suction feeding kinematics in the axolotl (Ambystoma mexicanum).
This blog post summarizes our recently published paper in Biology Open, in which we explored how size and developmental stage affected the feeding kinematics of larval, juvenile and adult Ambystoma mexicanum (axolotl). Peadomorphic species: are the adults just big larvae?…
Meta-Morphosis the project! A Documentary Video
Patricia Teixidor interviews the Meta-morphosis team for an in-depth explanation of the project and its relevance to amphibian conservation, including a behind-the-scenes look at the collections and science laboratories at the Natural History Museum of Bern.
Day trip to the Ozarks, Arkansas: Exploring the rich diversity of salamanders in the wild
Photos from our field trip in the Ozarks of Arkansas, where in a single day we encountered more than seven species of salamanders.

Chasing dragons in a laboratory cave
Do you like caving ? In early September, Anthony Herrel and I went to Moulis (Ariège, France) to visit the CNRS laboratory cave part of the SETE, hosted by our collaborator Olivier Guillaume, without whom this would not have been…

How do we prepare specimens for scanning?
In order to observe the precise morphology of the head bones, we use a micro-computed tomography (micro-CT scanner). This is a 3D imaging technique using x-rays to see inside an object, slice by slice. For our project, we need to…
Filming salamanders at the Amphibian Foundation
Why salamanders are so special? Were you aware that Salamanders present the most important diversity of developmental strategies among vertebrates? Most salamander species have what we call a biphasic life cycle, meaning that, like the frogs, eggs are laid in…
