Excited to release our #openaccess 3D model of a 33-year-old male African Bush Elephant (links below) that we scanned in Kenya with @savetheelephants.bsky.social - we believe that this is the most accurate 3D elephant created to date. Thx to Giacomo D'Ammando and STE org for funding & assistance

The original Caribbean reef shark model and animation was made by 3D artist Robert Gutierrez (www.artstation.com/bgut) for digitallife3d.org. I want to extend a big thank you to @duncanirschick.bsky.social for providing such a wonderful library of creatures for non-commercial creative projects!

Great article written by Joel Gayford & @physiologyfish.bsky.social on our recent paper in Royal Society Open Science Journal using #3D models to study shark scaling. Credit also to co-authors Johnson Martin & Andrew Chin as well. theconversation.com/sharks-come-...

Sharks come in many different shapes and sizes. But they all follow a centuries-old mathematical rule
A new study proves for the first time that the ‘two-thirds scaling law’ applies to large animals as well as small ones, offering key lessons for conversation.

A question - I realize that there may not be a good answer - is NSF still accepting proposals for Ecology/Evolution work, & does anyone know any awards are being given out? I'm working on an NSF grant with a colleague, and it's not clear from the outside what exactly is happening on the ground. TY!

New 3D model release! In collab w/Vienna Museum of Natural History, we retopologized and animated their 3D scan of an adult male Komodo dragon - Thanks to Mohammed Al Zubaidi and Josh Medina for CG work, and Viola Winkler for working with us! 😆🦎 3D model link skfb.ly/pvWts

Special thanks to collaborators Chhandak Bagchi (lead author), Fredrik Christiansen, Subhransu Maji, and Josh Medina. Thx also to the Center for Data Science at UMASS Amherst and various undergrads and CS students who helped with the project! 😀🦎

Results show that our model accurately tracks seasonal body condition changes. This automation can significantly reduce the time needed to calculate body conditions, enabling faster, large-scale whale health assessments. 🧵

Duncan J Irschick @duncanirschick.bsky.social · 10/03/2025
Trained on 468 annotated images, the model processes 8,958 drone images with 99.2% success. It estimates body length with 0.85% error and volume with 6.88% error, significantly speeding up body condition estimation while maintaining accuracy. 🧵

New paper with colleagues! Bagchi et al published work in Remote Sensing in Ecology and Conservation 😃 This ML model automatically extracts whale body length & volume from aerial images! Using Mask R-CNN, it detects whales, traces their body shape, and estimates the body axis. 🧵

I want to thank Aaron Olsen, who did the bulk of the 3D reconstruction of Emma - a large (size unknown, ~14 foot female) Tiger Shark from the Bahamas. Johnson Martin also helped Aaron. Both were rock stars in this work! And thanks to Neil Hammerschlag, who provided images/video (like below)
