Bats how many legs




















In this respect, the bat's nocturnal behavior provides certain advantages. Enormous numbers of insects fly at night, and with the exception of spiders, there are few competitors for such food. Other than the occasional owl or snake, there are also few predators that can capture or pursue a bat in the dark.

Night brings cool temperatures which help dissipate the heat generated by the muscular activity of flight. Because the bat has a thin wing membrane, flying during the heat of the day could be hazardous causing excessive absorption of heat and resulting in dehydration and possible heat prostration.

Nocturnality offers protection from the heat and helps the bat maintain its body temperature and moisture. All bats can see, even though vision may be less important than other senses.

To locate and catch prey, insectivorous bats use an acoustic orientation called echolocation. They emit a series of supersonic cries through the mouth or nose and detect flying insects by the echoes reflected back.

Those species that produce sound through their noses usually have a flap of skin called a nose leaf above the nostrils. This may help to direct the sound, but its precise function is not known. The man credited with discovering that bats emit sounds in the ultrasonic range and navigate in response to echoes is Donald R.

Since his first findings were announced in , numerous studies have been made in the field of echolocation, and it is the one area of bat life that has been investigated in any depth. In addition to the ultrasonic sounds used in echolocation, bats also emit other sounds possibly to communicate or to indicate emotion.

Purrs, clicks, and buzzing often precede mating of some species; some of these sounds may be ultrasonic. It has been observed that certain North American insectivorous bats vibrate when at rest and content. This vibration does not occur when they are asleep. Also, recognition of mothers and babies involves both audible and ultrasonic sound.

The bat's ear is extremely mobile and sensitive to sound. The tragus, a lobe projecting in front of the ear opening, may have a sensory function; however, its exact use is not known. According to analyses of stomach contents and the insect remains found near bat roosts, species vary in the insects they prefer. For example, the cave myotis, M. Small insects are often caught directly in the mouth, but larger ones are more frequently captured by the wing membrane, transferred and readjusted in the basket formed by the hind legs and the interfemoral membrane, then pulled to the mouth and eaten.

Not all bats seize their prey on the wing. Some specialize in catching land insects like grasshoppers or roaches that are found on the ground, rocks, or trees. In this instance, less energy is required to catch a few large insects than hundreds of tiny moths or gnats. Other bats use their feet to snatch insects from the surface of ponds and lakes.

With the exception of three flower-eating species that migrate from Mexico, the bats in the United States are insectivorous. Those species that eat pollen, nectar, and in some instances, petals from flowers, are found mainly in the tropics and semitropics. Pollen, like insects, is highly nutritious. The flower-eaters are usually small and have long pointed heads, long tongues, and the ability to hover and fly slowly. Fruit and sometimes insects also supplement their diet. Most of the Old World fruit and flower eaters rely on vision and sense of smell to locate food rather than sonar.

Unlike birds, bats are color blind and, therefore, not dependent on color for locating and choosing their food. Many prefer dark green or brown fruits with musty or sour odors instead of the more colorful varieties.

These fruits usually hang from vines or grow from the trunk of a plant unobstructed by heavy tropical foliage. A few species of bats are carnivorous, eating small frogs, lizards, and birds. Other species are known for their fish-eating habits and are usually specialized by having huge hind feet and claws. The best known of the fish-eating bats is the fishing bulldog bat, Noctilio leporinus , of Central and South America. How this bat actually finds its food is not completely understood, but many authorities believe that sonar is used to detect ripples on the water made by the fish.

It catches its prey with large hooked claws, spears the fish with its canine teeth, gathers it up in the wing membrane, bites through the skull and eats it, all in a matter of seconds. Animals Wild Cities Wild parakeets have taken a liking to London.

Should tears occur the body has the ability to repair itself. The wings have Merkel cells on them and this is why they are so sensitive. This also found on human fingertips. All bats have very tiny teeth that are razor sharp. They can easily bite through the skin of fruits or prey. They also have a very long tongue that they use for eating, drinking, and pollination. They can roll that tongue up around their rib cage too when not using it.

Bats have one way valves in their arteries so prevent the blood from flowing backwards. I think I have no idea how many legs a buttfly has. Butterflies have six legs. Many legs many starfish are unique so they will have different numbers of legs.
