They are poisonous nochesvetki jellyfish – Pelagia noctiluca. They were the first to be seen by the hotel staff when they went around the beach.
As experts remind, if a jellyfish comes into contact with human skin, it can result in a severe burn or allergic attack. Sometimes there are even scars. The management of local hotels have already been notified to be ready to help the victims.
Australian zoologists at the University of the Sunshine Coast have conducted a study to find out how crocodiles court their partners. These fearsome reptiles don’t seem romantic on the outside, but experts say we underestimate their ability to show lovemaking.
It turned out that to attract females, the male makes hissing sounds, splashes water from his nostrils and blows bubbles in the water. And females are simply delighted by this!
Several cameras and acoustic recording devices were installed in the crocodile enclosures of the zoo. It was recorded that females during mating games more often emit a peculiar roar, but the males imitate “geysers” with their noses.
Over thousands of years, dogs have evolved under the control of humans, contributing to many unique breeds through selective breeding. Originally, dogs were needed to guard herds, homes and for hunting.
Today, however, many dogs serve their owners simply as pets for companionship and friendship. The breeding process has not only empowered breeds, but has also had negative consequences. For instance, flat-faced breeds face breathing problems due to narrow nasal openings and short airways.
Let’s imagine a scenario in which dogs were left without humanity. The results would be unimportant. Breeds that are highly dependent on humans would not successfully adapt to independent living. They would face enormous difficulties in adapting. However, less than 20% of all dogs will be affected. Most animals around the world are homeless and live on every continent except Antarctica. Without our intervention, natural selection will begin to play a role in the lives of dogs.
First of all, any predator should be made to realize that a human is in front of him. Usually, wild fauna representatives avoid confrontations with humans. As Sutyrina noted, if an animal realizes that a human is making a sound, in 99 percent of cases it will not contact him.
Of course, all sorts of things happen in the forest, so if you find a fresh tiger track, you should move in the opposite direction. If you do meet the animal, you should not run away. You should start talking in a loud and calm tone, giving the predator a chance to leave, and slowly retreat without turning your back to the tiger.
Elephant trunks are characterized by great strength, flexibility and agility. Now scientists from the Chinese Academy of Sciences seem to have figured out how the largest animals on land managed to develop such outstanding organs.
It is noted that elephant trunks are a miracle of evolutionary biology – they can reach two meters in length, they have about 40 thousand individual muscles and nerve fibers, and they can lift objects weighing up to 270 kilograms, but they are able to gently lift a nut. For a long time, the natural and biological factors that helped the evolution of trunks have puzzled the scientific community, but now the veil of mystery has been lifted.
During their research, scientists compared three major families of elephant-like mammals, namely Amebelodontidae, Choerolophodontidae and Gomphotheriidae, which lived in northern China from 11 to 20 million years ago and are the ancestors of modern elephants. Scientists analyzed the enamel of the teeth of these animals to get an idea of where they lived and what they ate.
