Thanks to a new platform called Antscan, it has never been easier to link to or even interact with micrometer-resolution reconstructions of ants. This groundbreaking effort is a tremendous demonstration of a large dataset. It was created by digitizing over 2,200 of the world’s preserved ant specimens collected from collections across the globe. Antscan is operating the latest generation high-resolution micro-CT technology at the synchrotron light source facility in Karlsruhe Institute of Technology in Germany. This exciting development has expanded opportunities for research and learning.
Antscan features full coverage for 792 species in 212 genera. One of the first indications of this stunning diversity comes from one of the coolest aspects of ants. Researchers, educators, and enthusiasts can now point to the tidal wave of information available. They’re able to investigate this data using an interactive online portal that allows users to rotate, zoom, and virtually dissect ants. The website provides detailed, high-resolution pictures that highlight the external morphology of these beautiful little animals. It underscores the stunning complexity of their internal structures.
Advanced Scanning Technology
Antscan was developed by the painstaking 3D digital scanning of ant specimens. This complicated process preserved their calcified skeletons and bodies in astonishing detail. Scientists used a synchrotron micro-CT technique, which harnesses powerful beams of X-rays to create incredibly detailed images. This new technique allows the 3D visualization of other internal structures, such as muscles, nerves, digestive tracts, and even stingers.
Evan Economo, a prominent researcher in the field, remarked on the significance of this technological advancement:
“This is kind of like having a genome for shape.”
The application of neural networks and specialized software for data reconstruction adds an extra layer to both depth and usability of the dataset. Antscan then renders 3D volumes that richly depict each specimen. This amazing lending tool, run by the Smithsonian Institution and supported financially by our partners at the U.S.
A Rich Resource for Research and Education
Antscan’s impressive dataset will make it a great resource for comparative research between ant species. Cameron Currie noted the platform’s potential:
“It provides an outstanding resource for comparative work across ants.”
The accessible dataset provides an extraordinary opportunity for scientists to explore patterns on the entire ant family tree, tracing evolutionary relationships and convergent adaptations. I’m particularly interested in how species allocate their biomineral “armor” layers. This unique distribution provides important information on how ants allocate investments to their protective coverings.
The dataset is still being made more accessible. This creates valuable opportunities for interdisciplinary collaborations between education and research, and helps catalyze innovation in fields such as robotics, AI and engineering. Economo expressed hope for the future impact of these resources:
“It is an extremely rich dataset that can be used for a number of different applications in science, but also for the arts and outreach and education.”
Antscan not only facilitates current research efforts but creates a permanent record of ant anatomy that can be revisited long after fragile specimens degrade or wild populations disappear. This anatomical time capsule is extremely important for future studies of entomology and other related fields.
“I would really like to see these big libraries of organismal form one day be useful for people in robotics and engineering, so they can mine these data for new kinds of biomechanical designs.”
A Permanent Record of Ant Anatomy

“The full advantage of this dataset will be realized when these methods are deployed.”
Furthermore, David Blackburn emphasized the value of accessibility:
“The more people that access and work with the stuff in our museums, whether it’s physically or digitally, the greater value they add.”
