Catfish can hunt pigeons, and bees boil hornets alive - amazing facts about animals.
Sharks hunt with the sun
Sharks change their hunting tactics depending on the time of day. At least, this is typical for fish living off the coast of South Australia. A group of researchers observing the behavior of animals found out an interesting fact: in the morning and in the evening, sharks turn their backs to the sun. Ichthyologists came to the conclusion that this behavior is effective for hunting: firstly, in this case, sharks are less blinded by sunlight and they can better see their prey, and secondly, the predators themselves become less noticeable for their prey.
Catfish prefer pigeon meat
Catfish living in the Tarn River, in the south of France, are addicted to such a strange delicacy for fish. In order to catch a pigeon, catfish quietly swim up to it, if necessary - slowly chase their prey, and then grab an unsuspecting bird and mercilessly devour it. Interestingly, as it turned out during the study, catfish probably do not see the pigeons themselves, but they feel their movement along the ripples in the water.
Male black bears are real pursuers
Female black bears are capable of attacking humans if they decide that they pose a threat to their offspring. But the only thing they want from you is that you quickly leave their territory. Much more terrifying are the males of this species of animals, which can "target" a person as their victim, track him down for a long time, stubbornly and almost silently, and then swiftly attack and tear him to shreds.
Spiders "hire" predators as bodyguards
The predators themselves, of course, are unaware of this. Many members of the spider family are poisonous, but few have a sufficiently powerful bite, so they need to use cunning. For example, the small jumping spiders Phintella piatensis, which live in Southeast Asia, are very fond of many predators as a snack, say, tailor ants or spitting spiders. The latter even arrange "dwellings" above the houses of the jumping spiders to be closer to their dinner. However, the horses - the guys did not miss and learned to use enemies as their own bodyguards. To do this, jumping spiders arrange dwellings above the nests of tailor ants, which, in turn, love to feast on not only themselves, but also spitting spiders - enemies, apparently, more terrible for horses than ants. Despite this terrible neighborhood, some of the jumping spiders manage to survive, so the tradition of settling next to predators is passed on from “fathers” to “sons”. Imagine that people, fleeing, for example, from bears, would settle nearby with lions.
Vampire bats can run
Despite the fact that vampire mice are great at flying, they turn out to be also quite good runners. Having reduced the speed, the animals fall on four legs and jump, reaching a speed of 7 km / h.
Bees boil hornets alive
The giant Asian hornet is a very dangerous insect. This is understandable - its dimensions reach the thumb of a person, and in just a minute he is able to kill forty honey bees. But Japanese bees have learned to defend themselves against the formidable predator. Their secret is simple: "one for all and all for one." When a giant hornet attacks, a swarm of bees does not try to escape scattered, but, on the contrary, surrounds it as close as possible, forming a hot bee ball. The temperature inside such a ball reaches 47 degrees Celsius! And the hornet is literally being cooked alive in it. Several bees, of course, die heroically, but most of the insects remain in full health.
Starlings can master grammar
Starlings have the ability to imitate onomatopoeia.In this regard, scientists decided to find out whether these birds will be able to master complex grammatical structures inherent only in the human language. The answer turned out to be positive, however, in order to achieve this from starlings, you will have to stock up on a fair amount of patience and time. It took the researchers several months to train the birds to recognize and grasp a grammatical construct in the middle of a sentence. While starlings, however, cannot use memorized grammar rules to answer a person, but this, according to scientists, is only a matter of time.
