What Sharks Will Not Eat
Sharks will eat anything. The only exception, is that they will not eat anything in the vicinity of where they give birth. This is the way nature protects them from accidentally eating their own babies.

Sharks and Cancer
Sharks almost never get cancer. Scientists are studying them to find out why, and whether their protection is adaptable to humans.
Shark Competition
One species of shark is so competitive that the babies fight each other within their mother, until only one is left to be born.
Fishing Lantern
While fishing at a pond in New York State, a man lost the glass part of his lantern. Five years later, once again fishing in the same spot, he caught a fish that was wearing that same glass lantern chimney, stuck around its body.
Three Fish at Once
A fisherman in England hooked three pike at once. While pulling in the first, it was eaten by a second who was eaten by the third.

Pacific Salmon

Catfish Tastebuds
Some catfish have taste buds over their entire bodies. Wouldn’t that be fun at a potluck?
Hagfish
The hagfish has terrible table manners. It starts its meal by biting into the gill of another fish. Then it eats its way into the fish’s throat. Finally, it crawls totally inside the victim and kills and eats the fish from the inside out. These hagfish have four hearts and they all beat with independent rhythms.

Living Fossils
Everyone knows that there are places underground that have fossils 70 million years old. What most people don’t realize is that these things didn’t all die. Scientists bored a hole 850 feet down into the era of dinosaurs and found 3,500 living, undiscovered species of fungi, protozoa and bacteria. The scientists do not know whether these are the same as those who lived in prehistory or whether they have mutated.
Dinosaurs

Some dinosaurs had two brains. Since nerve signals move from one part of the body to another relatively slowly – it takes 1/50 of second to notice a pain in your foot – and since these beasts were so large, they had a second brain at the base of the tail to maintain control of the creature’s back legs and tail. Interestingly, the rear brain was bigger than the front brain.
The Largest dinosaur, Brachiosaurus, weighed as much as 800 people, was taller than a four-story hotel, and was as long as two of the longest school buses.
Who says all dinosaurs have died? There is a species of lizard called Komodo Monitor, also known as Komodo Dragon, that can grow to over ten feet long and weigh 365 pounds. Komodo Monitors can eat a pig whole.
Most scientists are now saying that dinosaurs were very unlike lizards. Their legs were usually directly under their bodies, not sticking out from their sides as they are in lizards. Their bone structure was more like that of warm-blooded mammals. Tracks have been found made by of groups of dinosaurs moving together in herds with a spacing and depth of impression indicating sustained high speed, again more a mammalian trait than reptilian. One theory regarding the extinction of dinosaurs which is gaining some acceptance is that because they were warm-blooded creatures with a high metabolism, they were more susceptible to viruses or bacterial infections than their cold-blooded predecessors. According to one scientist, they might have all died of diarrhea.
