| 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 |

| 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 . | | Location: | N43.05647 W124.44060 South end of Mile 97 | | Date: | 10/22/2008 |
