All species of bats have eyes and see. The lights from flashing cameras or flashlights really bother them. Most species move around and catch prey with the help of sound. Bats release sound signals through their mouth and nose. These signals bounce off of barriers in space or off of prey and are intercepted by the bat's large ears. In fact, they “see” with their ears. This kind of orientation is called ECHOLOCATION. Bats use echolocation to detect prey. They can find an insect the size of a mosquito in the complete darkness, and there really is no reason to fear that they will get tangled up in your hair. Humans cannot hear most of the sounds they make, as they are made at high frequencies. Dolphins and whales use the same orientation system. Different species of bats make different kinds of noises. Scientists can use special instruments called ultrasound detectors to determine which species of bat is flying.
Only three species of bats feed exclusively on blood, primarily the blood of livestock. These bats live in Central and South America. Most bat species feed on insects, moths and spiders. One bat alone can eat hundreds of insects in a single night (between 600 and 1000 mosquitoes), and therefore bats have an irreplaceable role in controlling the number of nocturnal insects, many of which are agricultural and forest pests. This is why we say that bats are a natural and BIOLOGICAL PESTICIDE.
This is a myth, but the result of it is that this marine creature has been massively hunted for centuries, and has become an endangered species.
Seahorses have been used in the human diet for more than 2000 years. In addition to the traditional believe that they increase sexual appetite, they are also believed to ease respiratory problems.
According to the assessments of the National Oceanography Institute, trade of some 20 million seahorses occurs throughout the world each year.
