OBSERVER D Bilderback EMAIL   •  REPORT PUBLISHED 11/30/08 3:42 PM  •  EDITED 11/30/08 3:46 PM PHOTOS 1 Dead California Sea Lion Location: N43.05647 W124.44060 South end of Mile 97 Date: 10/22/2008 2 Skull of California Sea Lion Description: The large bony protrusion above the skull is the sagittal crest. Sexually mature California Sea Lions have this enlarged sagittal crest. This is one way to determine the difference between a Steller's Sea Lion and a California Sea Lion if there are no other parts left of a carcass. Location: N43.05647 W124.44060 South end of Mile 97 Date: 10/22/2008 3 Teeth of a California Sea Lion Description: The decayed teeth are one sign that this animal probably was an older animal. Location: N43.05647 W124.44060 South end of Mile 97 Date: 10/22/2008 4 California Sea Lion with Cookie Cutter Shark bites Description: This carcass has round circular scars that probably are from Cookie Cutter Sharks (Isistius species). These sharks have large lips that enable them to attach to a prey. Then the animal spins and uses its deep teeth to cut a cookie-cutter shape of tissue out of the prey. We do not know whether the sharks ate this animal before or after the death of the California Sea Lion. A good website with great pictures of the Cookie Cutter Shark is at http://www.shark-pictures.com/viewpic/cookie-cutter-shark-teeth-structure-625.html .
