Necropsy and Skeletal Mount of Orca L51- 1999

Orca L51 Removed From the Strait of Juan de Fuca
On the weekend of September 25, 1999 a dead female Orca was reported by a Canadian Coast Guard employee, Wayne Ingalls.
It was floating in the area of Christopher Point near Bentinck island at the eastern end of the Strait of Juan de Fuca, just adjacent to Race Rocks. On Tuesday, the 28th we were informed at Pearson College and a team of students from the diving service went out to secure the body in a small bay near the Point.

The Finished product of the work of skeletal preparation of L51 is now  suspended above the lab benches in Catrin Brown’s Biology Lab. The mount was made by students and Hans Bauer, a former faculty member who volunteered for the job, along with Hugo Sutmoller.

A serious contaminant of Orcas in the southern Vancouver island area is PCBs. Male Orcas accumulate these chemicals throughout their life, whereas females are purported to increase in levels until a birth, whereupon the levels in the tissue drop as a result of lactation.
