During feeding, the gray whale appears to prefer using its right side to scour the bottom and find its food. This has been noted by several long time observers. To feed they gulp mouthfuls of mud from the bottom, then use the whiskery baleen as a filter to drain out the unwanted material. This leaves the amphipods stuck to the baleen inside their mouths. They then use their tongues to loosen the amphipods from the baleen, and swallow.
Whales are mammals. They breath air, have hair (calves have hairs around the front of their heads), are warm blooded, and give birth to live offspring that suckle milk from their mothers. The gray whale is in the sub-order Mysticeti. The Mysticeti whales have baleen instead of teeth. The male gray whale can reach 45 feet, while the female can reach 50 feet and weigh 30 or 35 tons. The largest grey whales have flukes, or tails, that may span ten feet.
Length about 40 to 50 feet. Weight about 50,000 to 80,000 pounds. I have read that they live up to 50 years. Just like people, once they reach middle age, they seem to get broader . The Gray Whales have a double blow hole.
If you ever get a chance to visit Oregon go to Depoe Bay and take a ride on the "Whales Tail"
