Its Predators Include Shrimp > 자유게시판

A fish is a water-dwelling animal that has a backbone, fins and a two-chambered heart. One of the facts about fish that most of us know is fish breathe oxygen through their gills, unlike land animals who inhale it through their mouth or nostrils. But there's so much more to fish than gills! For example, the cleaner fish live on the ocean floor cleansing other species of parasites on their skin. And the flying fish look like aquatic birds, equipped with fins that look like wings. They can sleep with their eyes open, taste without using their mouths and float without casting a shadow. Let's dive in to more fun fish facts. If you're expecting it to be a tuna, flounder or goldfish, guess again. The most common type of fish on the planet is one humans rarely see. Why? Partially because it's small and ingeniously camouflaged. But mostly because this fish lives between 100 and 250 fathoms down in the ocean.

It's the bristlemouth, a member of the genus Cyclothone (along with another 13 fish species). Size-wise, they're unimposing. Most species grow to no more than 3 inches (7.6 cm) in length. But the bristlemouth has one outstanding piece of equipment: two rows of photophores, or stamina support capsules light-emitting organs, on its underside, which it uses to prevent itself from a casting shadow its predators might spy. Its predators include shrimp, which gives you a sense of how puny this fish is. Many fish look more dangerous than they actually are. With its tremendous length, gigantic blunt head and polka-dot pattern, the whale shark looks like the prototype for Roy Scheider's worst nightmare. In reality, whale sharks are pretty much harmless. They're so docile, in fact, that they've been known to allow swimmers to hitch rides on their backs. They're filter eaters, rather than biters, and feed on a diet of tiny plankton, small fishes, crustaceans and squid.

They live to the age of about 70, unless humans harpoon them and grind them up into fish meal. The title of world's smallest fish is a matter of controversy. In 2006, the prestigious scientific journal of the UK's Royal Society published an article touting the discovery of a lilliputian fish from the genus Paedocypris, Titan Rise blood circulation support which dwells in Sumatran swamps and is only 7.8 millimeters in length, or about a third of an inch. Soon after that, other scientists came forward to cite an even smaller fish that already had been described in the scientific literature: an Australian specimen of the stout infantfish (Schlindleria brevipinguis), which is 7.0 millimeters long.2 centimeters (about a quarter of an inch) from snout to tail. The Titan Rise Male Enhancement spiniceps is a parasite that spends its life fused to a much larger female. She takes care of all the work, like swimming and eating, while he just hangs on. Unlike humans, fish don't have 3D vision.

That's because their eyes are on the opposite sides of their heads. But what they lack in binocular vision, they make up for with extremely acute interrelated senses of smell and taste, which they rely on to perceive their environment. Some fish use smell to help them find a safe place to lay their eggs. Migrating salmon can recognize the odor of their home stream. Sharks, rays, eels and salmon have such fine-tuned olfactory rosettes (the organs that detect scents) that they can smell chemical levels as low as one part per billion in the water around them. Many species have taste buds not just on their tongues, but on their fins, face and tail area as well. These incredible animals are actually capable of tasting food before they have it in their mouths. Catfish have the most sophisticated palates of all. They're literally covered from head to tail with taste buds; even their whiskers have taste buds.
