Today, on April 17, all animal rights activists and wildlife lovers can join the event dedicated to one of the most mysterious animals on our planet - World Bat Day, UNN reports.
Today, there are about a thousand different species of bats in the world. Most of them are on the verge of extinction. All known species of bats in the Ukrainian fauna as of 2023 are listed in the Red Data Book of Ukraine.
Bats are the only mammals that actually fly, flapping their wings to propel themselves in flight. It is believed that their level of intelligence is comparable to that of dolphins and horses.
The life expectancy of bats reaches 15 years.
Bats can see with their ears: by emitting a series of ultrasounds at frequencies of 20-120 kHz, they can distinguish objects as small as 1-10 mm by perceiving the echoes. This allows bats to fly in the dark and see insects.
In a day, a bat eats insects weighing up to 1/2 to 2/3 of its body weight, catching them in flight or hunting them on tree trunks.
