A family kayaking along the British coast made an unusual friend. A dolphin started swimming along with the family and entertaining them with his antics. The animal seemed primarily interested in 14 year old Lucy Watkins, especially so when he brought a 10 pound cod to withing 5 feet of her boat. Then , as if to say, 'join me for dinner' he dove and came back up with a sea bass for himself and started eating. A very nice gesture for a new friend.
Jake Allgeier studies fish urine. I guess someone has to. He says that there's a lot more of it than you would think, and it's a lot more important for marine environments than people realize. From redandblack.com:
"A funny comparison is if you take the biggest ungulate herd — so that would be bison, antelope, deer and elk — in Yellow Stone National Park, per meter squared — so per unit area — the fish on one of the reefs that I look at...they actually pee more than three times more [than that herd]," he said. Fish urine even dwarfs fertilizer-heavy golf course runoff — per meter squared — in nutrient content.
Mrs. Keyte of Blockley, Gloucestershire had a pet trout that would eat worms from her hand. When it died in 1855, she erected a tombstone in its honor. That tombstone remains one of the most popular tourist attractions in Blockley. And it's perhaps the only tombstone for a trout in the world. [National Geographic, 1917]
When these 3 to 5 foot catfish in France senses some motion on the shore, they have adapted their behavior to catch pigeons for dinner. They actually come onto the shore to get the birds. Here's a video of a successful catch.
According to the Public Library of Science, the fish have a 28 percent success rate, which is way better than any hunting or fishing I've ever done.
Scientists are studying a relatively new and unusual species of Vietnamese fish. Phallostethus cuulong carries its genitals on its head, both males and females. They also copulate because the the eggs are fertilized inside the female rather than after they are laid as many other species of fish do. Smart evolution, joining in the the fun part of reproduction!!
George Middlebrook was a Caribbean shark fisherman who made a pair of shark dentures for himself by taking a wax impression of his mouth, transferring the impression to wet sand, pouring hot lead into the impression, and then inserting shark teeth into the lead. (Google News link.) I wonder if he could actually chew with them? Because of his teeth, he was given a small role in the 1956 movie The Sharkfighters.
