THREATS • Decrease in fish stocks • Pollution • Vessel interactions Photo - Jared Towers Video - Chantelle Tucker
VOCALIZATIONS • Echolocate - prey and the marine environment • Calls – maintain group cohesion and convey pod identity Audio - Rachael Griffin Video - Chantelle Tucker

LUNA GUIDELINES: • Do not approach or interact with Luna • Do not stop or slow down around Luna • Maintain vessel speed and direction Photo -Rachael Griffin Video- Chantelle Tucker
ACOUSTIC RESEARCH • Over 200 calls analyzed • Luna uses three family calls
L98_1 is repeated twice Luna’s First Call in Nootka Sound (L98_1) Sound frequency (kHz) versus time (s) graph of Luna’s first call (L98_1) Audio - Rachael Griffin
Luna’s Second (L98_2) and Third (L98_3) Calls L98_2 L98_3 • L98_2 is emitted before L98_3 Sound frequency (kHz) versus time (s) graph of Luna’s second call (L98_2) Sound frequency (kHz) versus time (s) graph of Luna’s third call (L98_3) Audio - Rachael Griffin
SUMMARY • KILLER WHALES - males grow to 32 feet long, live up to 60 years of age, and live in family groups all their lives. • LUNA - juvenile male endangered killer whale alone in Nootka Sound, his mother is alive and he is making family calls. • LSP - crew go out on the water to educate boaters and encourage them to stay away from Luna.
