The National Oceanic and Atmospheric Administration - NOAA - says a two-week-old Hawaiian monk seal pup was killed and four other seals were injured in a dog attack on Kauai. The attack happened inside a fenced protection zone on a North Shore Beach on the Garden Island. A necropsy determined a dog bite most likely killed the 50-pound pup. The pup's mother had puncture wounds on her muzzle, indicating she may have been injured while attempting to protect her offspring. Hawaiian monk seals are an endangered species.
