Scientists Digitize Vaquita Skeleton to Preserve Endangered Porpoise
Scientists from Florida Atlantic University and partners have scanned a rare vaquita skeleton into a detailed 3D model, making the data publicly available. The project preserves the anatomy of the critically endangered porpoise while raising awareness of its plight caused by illegal gillnet fishing.

The vaquita (Phocoena sinus) is the smallest porpoise in the world, growing to about five feet in length and distinguished by dark rings around its eyes and a compact gray body. It is found only in the shallow waters of Mexico’s northern Gulf of California, where it has become a symbol of the urgent need to protect marine biodiversity. Decades of accidental entanglement in gillnets—especially those set illegally for the high‑priced totoaba fish—have driven the vaquita to the brink of extinction, with only a handful believed to remain alive today.
From a Fragile Skeleton to a Digital Archive
In 1966 a female vaquita skeleton was donated to the San Diego Natural History Museum. Because of its rarity and delicate condition, the specimen has been handled with extreme care and is rarely available for study. To preserve its anatomy without risking damage, a team of researchers led by Florida Atlantic University’s Jamie L. Knaub, with collaborators from the San Diego Natural History Museum, SeaWorld California, and NOAA Fisheries, turned the skeleton into a high‑resolution, freely accessible 3D model.
The digitization effort required about 165 hours of scanning and produced three terabytes of data. The scans were performed at multiple scales: medical computed tomography (CT) for the overall shape, micro‑CT for fine internal structures, and high‑resolution photography for surface detail. Using specialized 3D imaging software, the team separated each bone from the raw data and reconstructed it into a detailed, interactive model that can be rotated, zoomed, and examined from any angle online through the MorphoSource repository.
Why This Matters for Conservation and Education
By converting a fragile specimen into a digital format, the researchers have created a permanent record that will survive even if the species disappears from the wild. The model is not only a scientific resource but also an educational tool that can be used in museums, classrooms, and public outreach programs. It allows students and researchers worldwide to study the vaquita’s unique anatomy without the logistical and ethical challenges of handling a living animal.
Beyond the scientific value, the project underscores the vaquita’s status as a global symbol of the biodiversity crisis in the oceans. The digital archive raises awareness of the species’ plight and the broader issue of illegal gillnet fishing, which continues to threaten marine life in the Gulf of California. By making the data openly available, the team hopes to inspire coordinated international action to eliminate harmful fishing practices and protect the vaquita’s remaining habitat.
Technical Innovation and Collaborative Effort
The success of the digitization hinged on the advanced imaging capabilities at the Berlin Family Bioimaging Lab at FAU. Tricia L. Meredith, Ph.D., director of research for the lab, emphasized that access to high‑resolution micro‑CT systems and the expertise to process large datasets were essential. The workflow combined medical CT, micro‑CT, and high‑resolution photography to capture both external morphology and internal bone architecture at micrometer resolution.
Senior author Marianne E. Porter, Ph.D., highlighted the importance of integrating multiple imaging modalities to produce a layered dataset that reflects the specimen’s true complexity. The result is a model that preserves anatomical fidelity while remaining fully interactive, enabling researchers to examine features that would be impossible to study with a single scan.
Next Steps and Ongoing Challenges
While the digital archive preserves the vaquita’s anatomy, the species itself faces an uncertain future. Conservation efforts have intensified, but the illegal gillnet fishing that kills vaquitas remains a major threat. International cooperation is needed to enforce bans on gillnet use in the Gulf of California and to curb the demand for totoaba swim bladders on the black market.
In the meantime, the open‑access 3D model will continue to serve as a valuable resource for scientists, educators, and the public, fostering greater understanding and support for the vaquita’s survival.
Key facts
- The vaquita is the world’s smallest porpoise, critically endangered due to illegal gillnet fishing.
- Researchers digitized a 1966 skeleton into a detailed 3D model available on MorphoSource.
- The project used medical CT, micro‑CT, and high‑resolution photography to capture fine bone details.
- The digital archive supports scientific study, education, and conservation outreach.
- Ongoing illegal gillnet fishing remains the biggest threat to the vaquita’s survival.
Why it matters
The digitization of the vaquita skeleton preserves critical anatomical data for a species on the brink of extinction and provides a powerful educational tool to raise awareness about marine conservation challenges.
Frequently asked questions
What is a vaquita?
The vaquita (Phocoena sinus) is the smallest porpoise species, measuring about five feet long and found only in Mexico’s Gulf of California. It is critically endangered due to accidental entanglement in gillnets.
How was the skeleton digitized?
Scientists used medical CT for overall shape, micro‑CT for fine internal structures, and high‑resolution photography for surface detail, then reconstructed each bone into a 3D model using specialized software.
Where can I view the 3D model?
The model is freely available on the MorphoSource online repository, where users can rotate, zoom, and examine the skeleton from any angle.
