With a tail that can be long as its body, the Thresher Shark attacks its prey with violent whip like motions.
This behaviour has been suspected by researchers, but only recently has it been caught on film. The tail is used to stun, maim or even kill the prey, with the shock-wave created by the momentum also stunning surrounding fish.
It is thought to be an evolutionary adaptation as these sharks hunt mainly smaller fish such as sardines. This makes the whip mechanism much more efficient at catching multiple fish with a single blow, as opposed to one fish at a time the shark would tend to catch with its jaws.
The tail was caught moving at up to 80 km/h, spontaneously heating and even boiling small areas of water near the very tip of the tail due to the extreme forces involved.
This is a “Penguin rover” used to study Emperor penguins in Antarctica.
It’s equipped with a spy cam to assist in studying these shy animals. Researchers found that approaching these emperor penguins normally would result in their heart rates rising, producing unreliable data.
This rover works very well, enough to even entice communication from the penguins. According to researchers the penguins were “very disappointed” when the rover didn’t respond, prompting the researchers to plan to have the rover playing penguin songs on it’s next trip.
One, remember to look up at the stars and not down at your feet. Two, never give up work. Work gives you meaning and purpose and life is empty without it. Three, if you are lucky enough to find love, remember it is there and don’t throw it away.
I wonder how many people have lay awake at night totally in awe about how stupid they have been … how much they trusted a person who broke them… how they thought they knew someone they clearly didn’t… how happy a person could’ve made them if… how old a relationship would be had it worked out… how long it takes to heal… how do they know hell isn’t this lifetime… how much they love someone… how much they miss someone… how many marks that essay’ll get them… how many more days before it ends… how many people have walked away… how much they’ve changed… I wonder, how many people are awake right now heartbroken, heartless or head over heels. - 4 am thoughts
