It is a myth that they blow water from their blowholes. As in all whales, the trachea and esophagus do not connect to their throat. But, their blowhole and trachea connects to their lungs. Air and mucus is expelled out of the blowhole. When expelled, this hot, moist air condenses upon contact with the cooler air outside, resulting in a spout that looks like water. So they are not really blowing water from their blowhole!
Maybe you have wondered where the humpback whale received his name? On his back, the dorsal fin is on top of a hump on his back which is noticeable when he arches his back and dives, and this is how he received his name.
They are the most acrobatic of all the whales. Have you ever seen them breaching, which is jumping high out of the water and then making big slap on the water as they come down? This is definitely a spectacular sight! I got to see humpback whales on a whale watch off the coast of California. No other whale leaps as often or as high as the humpback whale. It is not known why they do it.
Have you noticed the bumps on their head and lower jaw? Each bump is an oversized hair follicle. It is about the size of a golfball! Inside each is a stiff hair that might be used to sense their environment.
They breed and give birth in the tropics. The humpback female is pregnant for 11 to 12 months, and then she has about a 14-foot baby! When the mother sleeps, at first the baby stays close by. But after a few weeks, since the baby has lots of energy, it starts roaming. The baby will stay with the mom for one year during which time, the baby learns what to eat, how to find food, who to trust, who to fear and how to migrate.
Japan, Norway and Iceland are still killing whales. Sometimes, ships collide with whales and kill them. The solutions is to have the ships slow down around the whales, and maybe even change the ship’s routes.
Humpback whales do not have teeth, but have baleen which is a flexible material that hangs down from the roof of their mouth to filter the whale’s food. One of their favorite foods is krill, which is a shrimp-like planktonic crustacean. Baleen works very well for catching krill.
Whales sometimes feed in groups using bubble-net feeding technique. A group of whales go below a large concentration of small fish. Then, they blow bubbles that make a bubble net that trap the fish at the surface. The whales spontaneously swim through the bubbles, with their mouths wide open, catching thousands of fish. In one day, a humpback whale eats an equivalent of 8,000 hamburgers!
I enjoyed Humpback Whales 3D. Below, I am holding a piece of baleen from a humpback whale. #humpbackwhale #whale
