I have a good friend that will travel to great lengths to get the best sushi. Her favorite restaurant is here in SF (she lives about 25 miles outside of town), and she swears by their salmon and yellowtail. Little does she know that her raw fish obsession is one she shares with killer whales!
A recent study finds that salmon is killer whales' favorite food, and they will travel large distances to nosh on the best. Using their Ecolocators (creating an echoing sound), they can scan areas up to a half mile away to find their favorite King Salmon, which provides the high concentration of fats and lipids that these whales seem to prefer. I can see traveling 25 miles to a favorite sushi bar a couple of times a month, but scanning hundreds of miles of ocean for a particular fish? Now that's a dedication that my pal Yum could appreciate!
