UNLV builds soft robotic sea lion model for veterinary training

UNLV researchers have developed a 3D-printed synthetic California sea lion pelvic region designed to mimic both bone and soft tissue, giving veterinary teams a more realistic way to practice blood collection and potentially other procedures before working with live animals. The work, published January 21, 2026, in Scientific Reports, uses CT-derived DICOM imaging data to create anatomically faithful models with tunable materials and simulated blood flow. UNLV said the project was motivated in part by the ongoing stream of sick, stranded sea lions tied to domoic acid-producing harmful algal blooms along the California coast. (nature.com)

Why it matters: For veterinary professionals, especially those involved in marine mammal medicine, rehabilitation, and wildlife response, the model points to a practical training tool in a setting where hands-on opportunities can be limited and procedures can be technically challenging. Marine mammal blood collection is already recognized as difficult because of species-specific vascular adaptations, so a repeatable simulator could help teams build skill, reduce stress on live patients, and standardize training during periods of heavy stranding response.

What to watch: The next step is whether the platform moves beyond blood-draw training into procedure rehearsal, implant development, or broader veterinary simulation use across other wildlife and companion animal applications, as the authors and UNLV suggest. (nature.com)
