Pierre (February 16, 1983 – May 6, 2016) was an African penguin (Spheniscus demersus) who lived at the California Academy of Sciences in San Francisco.
In 1997, the then-14-year-old Pierre began coughing periodically, due to an allergic reaction inflaming the upper respiratory tract, treated with one or two daily doses of hydroxyzine.
He wouldn't swim much, since the water was too cold and he would have risked developing potentially fatal hypothermia.
Medical tests in 2007 revealed that there was no blood infection, the feather biopsies yielded all normal limits, and the only internal dysfunction seemed to be a low-grade kidney problem.
