Scientists in Bay Area are still confused about what killed an adult sperm whale after they performed a necropsy on the animal that was found dead at Sharp Park Beach.

The sperm whale about 49-foot-long was examined by a number of marine biologists, veterinarians, scientists and student volunteers. They were trying to figure out what killed the giant animal and how it got to the location near Mori Point.

The researchers said that it could take about a full day to determine the cause of death of the sperm whale. They concluded that the adult sperm whale was a male and it had exhibited signs of trauma.

Last Wednesday, Laura Sherr, spokeswoman of Marine Mammal Center, said that the scientists did not find any broken bone while conducting experiments on the mammal. She also said that the scientists found some hemorrhaging in the muscle of the whale. There was no evidence of blunt force trauma from something.

Sherr said that squid beaks were found by the scientists in the whale's stomach, which indicates that the animal had eaten at some point shortly before it died about one week ago.

Dr. Caitlin Brown, a veterinarian with the Marine Mammal Center, said that the test of the animal by the scientists was a very intriguing investigation because of the solitary nature of the sperm whale.

Scherr said, “Scientists finished the necropsy late Wednesday afternoon with no answers as to what led to the whale's death. Tissue samples taken are not fresh enough to help solve the mystery”. According to her, the Marine Mammal Center responded to about 17 stranded sperm whales in its four decades long history, which is the last large one in Point Reyes in 2008.
