Yes! I’m very fortunate to know several members of Kimalu’s team (which included 17 veterinarians in addition to their invaluable support staff*) and Kimalu herself! She’s a very sweet, very personable girl, and it was heartbreaking to hear she wasn’t doing well. For those unfamiliar with the case, Kimalu developed subcutaneous cysts around her blowhole that were causing her noticeable discomfort. It was determined that surgery was the best option for providing her relief.

The surgery itself was groundbreaking, but what’s even more miraculous is the anesthesia. General anesthesia was once considered impossible in cetaceans, due to their size and incredibly unique anatomy and physiology. For example, just intubating them requires manually dislocating the “goosebeak” (modified larynx that transects the esophagus) to allow for access to the trachea. That’s also why they can’t breathe through their mouth! Furthermore, they are voluntary breathers, and must be ventilated until conscious enough to breathe on their own again.

While general anesthesia has now been performed successfully a handful of times in smaller cetaceans, it had never been done in a beluga. In fact, Kimalu was only the second beluga in which anesthesia had even been attempted—and now, she is the first ever beluga to have woken up!

This is a gamechanger for belugas in human care (and maybe, somewhere down the road, in the wild). Now that we know surgery and anesthesia can be performed successfully, the scope of care we can provide them just got a whole lot wider. This is only the first step, but it’s a monumental one. And it goes to show the remarkable care zoos and aquariums provide their animals, as well as the contributions they make to scientific advancement.
