A Closer Look At Gray Whales
The most conspicuous identifying characteristics of gray whales are their size, distinctive mottled gray coloring, dorsal hump (no dorsal fin) and the knuckles along the back behind the dorsal hump.
Size: Gray whales range in size from 35 to 45 feet long, and weigh 30 to 40 tonsabout the length of a school bus and the weight of ten elephants, mush larger than a diver. Females weigh more and are longer than the males. Gray whales are intermediate in size in comparison with other well-known whales. By comparison, blue whales are 80 to 100 feet long and orcas (killer whales) are 20-25 feet long.
Coloration: Gray whales are so called because of their mottled gray coloration. The natural pigmentation can range from almost black to almost white, and can include white spots that range from the size of a marble to a basketball.This mottled appearance is enhanced by barnacles, barnacle scars, and whale lice.
Rostrum (Head Region): The rostrum extends from the tip of the snout to the blowholes, a length of about six feet. The rostrum of adult gray whales is covered with barnacles and whale lice. Gray whales that feed on the bottom, rub off barnacles and leave barnacle scars. Young gray whales have a dimpled rostrum with one hair in each dimple.
Eyes: The eyes of the gray whale are brown in color and the size of an orange. Eyes are located at the end of the mouth line, seven or eight feet from the rostrum tip.
Blow: The gray whale blow is 6-10 feet high and is heart-shaped if seen from behind on a calm day. About 100 gallons of air is expelled from the blow at speeds that range from 150 and 200 miles per hour.
Dorsal Hump: Gray whales have no dorsal fin, instead they have a dorsal hump at the end of the back.
Knuckles: 6-12 bumps called knuckles are seen behind the gray whale's dorsal hump. In some whales they are very distinct and in others they are not.
Baleen Plates: 300 blonde baleen plates about one foot long hanq from the top jaw. Bristles on the inside edges of those plates trap food organisms.
Blowholes: Gray whales have two blowholes like all baleen whales.
Throat Grooves: Two to five throat grooves on the bottom of the throat expand when the whales are feeding.
Flippers: Behind the throat grooves are pointed, paddle-shaped flippers.
Tail Fluke: An adult's tail fluke is 9 feet wide. When the tail fluke goes under the ocean's surface it leaves a characteristic print called a "fluke print".
Flukeprint: A large circle of smooth water formed by tail fluke turbulence when a whale dives.
The Celestial Poles
The north and south celestial poles are two imaginary points in the sky where the Earth's axis of rotation, indefinitely extended, intersects the imaginary rotating sphere of stars called the celestial sphere. The north and south celestial poles appear directly overhead to an observer at the Earth's North Pole and South Pole.
At night the stars appear to drift overhead from east to west, completing a full circuit around the sky in 24 (sidereal) hours. Of course, exactly the same motion occurs during the day, except that the stars are not visible due to the sun's glare. This apparent motion is due to the spinning of the Earth on its axis. As the Earth spins, the celestial poles remain fixed in the sky, and all other points seem to rotate around them.
