(Newser) – How does a tiger know when its prey is dead? It uses its ultra-sensitive whiskers to detect a pulse, or lack thereof. So says the Sierra Club in rounding up four animals with "superhero" abilities. Those whiskers have sensitive nerve endings, and after a tiger takes down its prey, the whiskers encircle the victim's neck to try to find a pulse. Others on the list:

  • Tiger moths: They deter their main predator, bats, by jamming the bats' sonar signals. When the moths sense the bats approaching, they release some 4,500 clicks per minute, essentially causing the bats to zig as the moths zag. No other animal can pull off such a feat.
  • Platypus: Not only can it pick up on electric impulses in the ocean, it has venom ducts hidden on its back limbs. The venom comes out when the platypus feels threatened.

They way they worded the platypus description made it sound like he had predators hidden in his hind legs! Ha!

"Including the not-so-humble pigeon, whose internal compass could put a smartphone GPS to shame." Yeah, then why can't they find a toilet instead of statues and cars?

What about sharks? Their skin doesn't allow barnacles to grow on them like other sea creatures, and their sixth sense allows them to survive in environments like the deep ocean and to hunt hidden prey (eg the hammerheads diet). shark week wouldn't have been created if there was nothing to talk about.
