I would never have guessed that the weapon of choice for a humpback whale is bubbles. Lots of bubbles. Researchers have found that these whales create what are called "bubble nets" around schools of fish. The fish see the tiny bubbles as a barrier that they cannot cross. The whales then swim through the barrier and feast on the trapped fish.
If only my fishing pole could be that successful.

I really love fishing! I can't think of a more relaxing time than sitting by the lake, or a more exciting time than going deep sea fishing. Therefore, I find animals that have come up with unique ways of catching fish pretty interesting. Take for example the humpback whales that we talked about in…
Perhaps you've heard about the wayward humpback whales, a mother and calf, who had become disoriented and began swimming inland towards Sacramento, California. They were traveling down the Sacramento River, causing a lot of grief to the Coast Guard and to marine biologists trying to think of a way…
Gray's paradox was originated by the zoologist James Gray in 1936 (J. Exp. Biol. 13: 192–199, 1936). The paradox questioned how a dolphin is able to swim fast (~10.1 meters per second according to his calculations) with what he saw as a limited ability to generate that much power. Therefore, he…
During the 1990's I can scarcely remember a time when one television station or another wasn't playing at least one of the four JAWS movies, TBS, TNT, or WPIX often devoting an entire day to films about killer oceanic creatures. Still, of the four films JAWS 3 (or 3-D, if you like) was one of the…
This has been very well known for about .. umm ... 40 years. Is this supposed to be a science blog?
I saw this in Alaska with 3-4 whales in a group. I am intrigued by how the group of whales coordinates the bubble nest together. Researchers should listen more closely to the whale vocalizations too.
