Young mantis shrimps pack an explosive blow that can separate water from just nine days old


Mantis shrimp does not pull punches! The study found that children pack an explosive blow that can separate water from just nine days old

  • Adult mantis prawns are famous for their quick, bubble-making punches
  • But a new study shows that shrimp have this ability when they are only 9 days old
  • A slow-motion video via a binoculars shows accelerating at 16,500 degrees per second, nearly 100 times faster than the Formula One.

Young mantis shrimp can produce a punch quickly when they are only nine days old and smaller than a grain of rice.

The powerful force of this type that can create bubbles is its most famous trait, and it uses it to seek shelter.

But a new study – which involved sticking baby shrimp to a toothpick and filming them in slow motion – found that animals were able to do this from a very young age.

Young mantis shrimp can produce a punch quickly when they are only nine days old and smaller than a grain of rice. Hard hit of these types that can make bubbles

Footage of the adorable little shrimp, which has transparent shells, reveals how it produced a punch and how quickly its limbs moved.

A team from Duke University showed that the limbs have a steep acceleration of 16,500 degrees per second, nearly 100 times faster than a Formula 1 car.

An adult mantis shrimp can strike its prey with a blow from its club-like tip at a top speed of 51 mph which is so fast that it creates bubbles in the water.

The collapse of these bubbles produces shock waves that give the shrimp a two-pronged attack and increases the chances of stunned or killed its prey.

A new study - which involved sticking young shrimp to a toothpick and filming it in slow motion - found that animals were able to do this from a very young age.

A tiny crustacean the size of a sunflower seed shuts off its paw 10,000 times faster than the blink of an eye

Young prawns capture their paw in less than 0.01 seconds, about 10,000 times faster than the blink of a human eye.

The movement is so fast that it creates an audible crackle over the water and creates bubbles.

The male of the species Dulichiella cf. The appendix is ​​very small, roughly the size of a sunflower seed, but 30 percent of its body weight comes from its huge claw.

The engorged claw shuts in at just 93 microseconds, and travels at 38 mph. It takes about 150 milliseconds for human eyes to complete the blinking process.

Doctoral student Jacob Harrison conducted research on young prawns captured as larvae in the ocean around Hawaii, and said it took more than a year to perfect his photographic method.

“It can be very difficult to collect the larvae,” he says.

It can be very difficult to sift through a bucket full of larval crab, shrimp, fish, and worms to find mantis shrimp.

“ I had to glue a 4mm larva to a toothpick, place it on a specially designed platform and direct the subject into the viewfinder view before I could even start collecting data.

“It took me about a year to explore the correct way to set up the camera before we knew we could capture these videos.”

But the footage they obtained reveals intricate details about the punches and how they were produced.

It appears that a muscle in their arm is contracting and pulling the appendix towards the animal’s body and forcing the rigid exoskeleton to bend.

This stores energy in the joint like a spring. The shrimp then releases an internal latch that holds the curve in place. This releases pressure and allows the arm to extend back at full speed to its normal position.

The study has been published in the Journal of Experimental Biology.
