Far from ordinary, a tiger ’s whiskers are more useful and mysterious than one might expect. Nerves at the base of the whiskers help tigers detect distances and changes in their surroundings. When tigers hunt, they go for the kill shot: the carotid artery located in the neck. After the tiger’s canines have pierced the artery, the whiskers move forward, encircling the prey’s neck, and determine if the prey’s pulse is gone.

Just like Clark Kent looks like a normal guy until he puts on the blue and red outfit comes, these seemingly-ordinary animals possess some extraordinary abilities. Find out which critter can sense electric impulses in the sea, which super-animal can jam a bat's sonar, and which creature has a better internal mapping system than your smartphone.







Pigeons have an internal clock that helps them find their way home. Since domestic pigeons don’t look for food of their own, they go on long, spontaneous journeys with no maps or breadcrumbs to help them find their way back. They use the position of the sun in the sky, for as long as it is visible, to complement their internal magnetic compass. The constant dance between these two mechanisms is referred to as the clock-shift.

3.) The Many Talents of the Platypus

This rather cute but unusual animal has quite a few surprising superpowers. The platypus has electroreception, which allows it to sense electric impulses in streams and rivers, it is one of the few living mammals that can lay eggs, but its coolest power has got to be the one hidden behind the thighs of its back limbs. Male platypuses have venom ducts located cleverly behind a single layer of thick skin. The venom is secreted by a gland when the platypus feels threatened by the presence of another species. Its venom is especially dangerous during breeding season and there have been instances of intense pain in humans and hunting dogs.

4.) In Defense of Bertoldia trigona

The tiger moth has recently been discovered to have the ability to predict an attack by a bat, the key predatory threat to this insect. Bats use echolocation, a type of sonar detection, in order to hunt at night: an extraordinary skill in itself. Found in the southwestern United States, the moth can hear the sonar signals sent out by the bat. In effect, the moth releases 4,500 clicks per second, which jam the bat’s sonar ability the way jammers can block phone signals. According to a study released in PLOS ONE, the clicking technique works 93% of the time and cause hunting bats to swerve in the opposite direction. This is the only animal, known to science, that is able to measure and block a predator’s sonar signals.
