Whale Watching Report For The Whales Tail May 23


Thank you Carol K. of Tallahassee, Fl. and Vanessa K. of the U.S.Coast Guard Station Cape Disappointment in Ilwaco, Wa. hope you both have a safe trip and I hope to see you again.



It was good to have Julie of Middleton, Id. and Tonne of Emmett, Id. aboard the Whales Tail, hope to see you in the future, you girls did great.

Aboard the Whales Tail we headed straight West as no whales had been sighted North or South of Depoe Bay. The skies started to clear and we had excellent visibility although the sea conditions were a little choppy along with a 7' swell. By late afternoon the wind and seas subsided somewhat and it turned out to be a nice afternoon. No whales were sighted today, but we did find the harbor seals and sea lions on the buoys and watched a crab boat working. I have high hopes tomorrow will bring us whales and calm seas.

Whale Bits
Gray Whales, and they Eat
Gray whales are opportunistic feeders, which means they will eat food from a wide range of sources. Along the coast of Depoe Bay, Oregon, it appears they feed on mysid shrimp found at the edge of kelp beds. Billions of mysids are found in the waters off Depoe Bay. In the Bering and Chukchi Seas in Alaska, they feed on bottom sediments packed with amphipods. There have been studies that have shown that prey items included anphipods, crab larvae, krill, ghost shrimp, pelagic red crabs, skeleton shrimp, mysids, small fish, polychaete worms and other organisms.

How They Eat:
Gray whales are baleen whales and they are in the Mysticeti category which means moustache whale. In place of teeth on the upper jaw, the Mysticetes have a series of overlapping plates made of keratin its the same substance as your fingernails. The inner margin of each plate, next to the tongue, is fringed with bristles that trap organisms but still allows water to pass through.

Feeding:
Hanging from the top jaw of a gray whale are blonde colored baleen plates about one foot long. The inside edges of these plates have bristles which trap food organisms like mysid shrimp or crab larvae. Like all baleen whales, gray whales draw in food-laden sea water and push it through the baleen plates, filtering out food with the bristles.

Heres how it works:
The gray whale depresses its 2000 pound tongue. This forms a suction and a piston that brings in water and small food items. Once the food-laden water is inside the mouth, the tongue is lifted up and the mysids become trapped on the inside edges of the baleen plates and the water leaves through the openings of the baleen plates. The tongue licks these bristles clean and then the prey move through the grapefruit-sized throat. Two to five throat grooves also expand when the whales feed to increase the surface area. Baleen plates hang from the roof of the mouth and these one foot long baleen plates filter food like mysids from the water.

Where They Eat:
Resident gray whales are most commonly seen feeding in and around kelp beds in water depths of 10 feet. Huge swarms of mysids live in these kelp beds during spring, summer and early fall. These huge swarms range from 3 to 20 feet thick and have billions of mysids. One gray whale is estimated to eat a ton of these mysids per day. One sign of grays feeding on these mysids is when a partial fluke is exposed at the surface.
