(Newport, OR) -- A wounded sea otter has died at the Oregon Coast Aquarium in Newport. The aquarium announced the death yesterday. The otter was found on Cobble Beach near Yaquina Bay with puncture wounds that were similar to a shark bite. The sea otter was initially alert and eating, but its condition changed, and it died after three days of care. It'll be sent to a U.S. Fish and Wildlife Service veterinary center for a necropsy.
