Toola, the "Most Important Animal" in the History of the Aquarium's Sea Otter Program, Dies
(Toola) was the first rescued sea otter ever to raise pups that were successfully returned to the wild; and was the inspiration for state legislation that better protects sea otters.
... she quickly became a pioneer for the Monterey Bay Aquarium - on exhibit and behind the scenes. Toola was the first otter ever to serve as a surrogate mother for stranded pups. She raised 13 pups over the years, including one that was weaned from her on Friday as her health declined. Of the 11 pups already released to the wild, at least 5 are still surviving - including the first animal she reared in 2001.
