Vaquita: Researchers digitally preserve the world's most endangered marine mammal
Researchers from Florida Atlantic University (FAU) have successfully created a highly detailed digital archive of the vaquita (Phocoena sinus), the world's smallest and most endangered marine mammal
Published in Marine Mammal Science, the study provides an open-access, interactive 3D anatomical record of the porpoise to aid education, research, and global conservation efforts.
An unprecedented extinction crisis
The vaquita is an elusive porpoise found exclusively in the shallow waters of Mexico’s northern Gulf of California. Measuring roughly five feet in length, it is distinguished by dark, prominent rings surrounding its eyes and mouth.
The species remained completely unknown to science until the second half of the twentieth century.
Today, only a handful of individual vaquitas are estimated to remain in the wild. Its rapid population collapse is driven almost entirely by accidental entanglement in gillnets—massive walls of fishing netting. Specifically, illegal gillnets are deployed to catch the totoaba, a large fish heavily targeted by wildlife trafficking networks for its highly prized swim bladder.
Despite an official ban on the totoaba fishery decades ago, illegal poaching persists due to strong international black market demand.
The Multi-Scale Imaging Process
Because physical vaquita remains are incredibly rare and fragile, direct handling must be strictly minimised. To build the permanent digital replica, the collaborative research team scanned a complete female skeleton collected in 1966 and preserved at the San Diego Natural History Museum.
The complex imaging workflow integrated multiple imaging technologies to map the skeleton at varying scales:
- Medical Computed Tomography (CT):
The full specimen was first run through standard medical CT scanners to capture thousands of cross-sectional X-ray images mapping the whole-bone morphology.
- High-resolution photography:
Individual bones and distinct skeletal elements were documented with high-resolution digital cameras to record external geometry and colour.
- Micro-Computed Tomography (Micro-CT):
Individual structures were subsequently analysed using micro-CT scanning systems. This advanced process maps internal bone architecture down to microns—a scale smaller than the width of a single human hair.
Maximising public and scientific access
Specialised 3D imaging software was used to isolate each scanned bone from the master dataset, digitally reconstructing them into interactive 3D models. These digital replicas allow scientists and students to rotate, scale, and examine every structural angle without risk of physical damage to the original 1960s specimen.
To maximise global impact, the final layered datasets and 3D models have been uploaded directly to MorphoSource, a free online repository. This open-access data sharing allows educational institutions, classrooms, and museums to download the blueprints and 3D-print scientifically accurate replicas, providing a permanent anatomical record of a species currently teetering on the edge of extinction.
