Baby mantises shrimp pack explosively, which can separate the WATER in just nine days



Praying mantis shrimps do not pull blows! Babies pack explosively, which can split WATER into just nine days, study finds

  • Adult mantises are known for their fast, bubble-striking blows
  • But a new study shows that shrimp have this ability when they are only 9 days old
  • Slow-motion microscope video shows limbs accelerating at 16,500 degrees per second, almost 100 times faster than a Formula One car

Baby mantises are able to produce a quick blow when they are only nine days old and smaller than a grain of rice.

The powerful blow of this species, which can make bubbles, is its most famous characteristic and it is used for hunting and finding shelter.

But a new study – involving sticking baby shrimp on a toothpick and shooting it in a slow cadence – found that animals were able to do so from a very early age.

Footage of the remarkable young shrimp, which have transparent shells, reveals how they produce a blow and how fast their appendage moves.

The Duke University team shows that the limbs have an acceleration of 16,500 degrees per second, almost 100 times faster than a Formula 1 car.

Adult mantises can smash prey with a stick-like blow from their appendage at a maximum speed of 51 miles per hour, which is so fast that it creates bubbles in the water.

The collapse of these bubbles leads to shock waves, which gives the shrimp a two-way attack and increases its chances of stunning or killing its prey.

A small crustacean the size of a sunflower seed snaps its claw 10,000 times faster than the blink of an eye

A small shrimp snaps its nail in less than 0.01 seconds, about 10,000 times faster than the blink of an eye.

The movement is so fast that it creates a sonic pop over the water and produces bubbles.

Males of the species Dulichiella cf. appendiculata are only small, about the size of a sunflower seed, but 30 percent of their body weight comes from its single huge claw.

The sunken claw closes in just 93 microseconds, moving at about 38 mph. It takes the human eye about 150 milliseconds to complete the blinking process.

PhD student Jacob Harrison conducted research on young shrimp caught as larvae in the ocean around Hawaii, and said it took more than a year to perfect his shooting method.

“The larvae can be extremely difficult to collect,” he says.

“It can be extremely challenging to sift a bucket full of larval crabs, shrimp, fish and worms to find the mantis shrimp.

“I had to stick a 4 mm super larva on a toothpick, place it on a specially designed platform and orient the individual in the view of the camera lens before I could even start collecting data.

“It took us about a year to figure out the right way to set up the camera before we realized we could shoot these videos.”

But the footage they received reveals complex details about the strokes and the way they were produced.

This shows that the muscle in their arm contracts and pulls the appendage to the animal’s body and forces the hard exoskeleton to bend.

This stores energy in the joint like a spring. The shrimp then release an internal lock that holds the bend in place and this releases the pressure and allows the arm to extend backwards, at an extreme pace, to its natural position.

The study is published in the Journal of Experimental Biology.
