It will, though, require more development to scale. It may well become even more efficient, because the researchers need not faithfully follow the biology of the pistol shrimp. In fact, Staack realized they could trim down the size of the upper bit of the claw. Then you can engineer a better system. Researchers might even want to look back to nature for ways to tweak the system.
Hundreds of species of pistol shrimp are snapping away out there in the sea, each with its own uniquely adapted claw. That and even individuals within a species vary in their morphology. So while the researchers can make their own tweaks to their claw robot, they can also draw inspiration from the inherent diversity of pistol shrimp to play with claw morphologies other than the one they originally 3D printed.
That diversity may one day see a pistol-shrimp-inspired device used in a range of fields. One approach would be to use claw-generated plasmas to drill through rock, as the crustacean does out in the wild to make a home in a reef. Or you might use the system for water purification by breaking up water into its constituent parts, which forms a peroxide.
Staff Writer Twitter. One idea might be to create a mechanical replica version of the pistol shrimp. Its not clear whether such energy production, even if driven by hydro or heat harvesting, would be more efficient than other methods of energy production.
Also what might be more difficult is maintaining the integrity of the vacuum bubble for anything more than a tiny size. The tiny size of bubbles could however perhaps be an advantage in other applications.
The small bubbles could be useful medicine for tumor destruction for example [3]. Another idea that has been floated has been a compression engine [4].

But there's one little weird wonder of the sea — the pistol shrimp — that crushes the stereotype in a dramatic way. It's so powerful it not only shoots and annihilates its prey; it has thrown the U. Navy off track, landed a superhero role on Netflix and even helped researchers make strides in fighting climate change.
Pistol shrimp, also known as snapping shrimp, earn their sea cred by creating something that's seemingly childlike and innocuous: bubbles. But these definitely aren't your ordinary bubbles — they make a sound louder than a gun and generate massive amounts of heat. Pistol shrimp "shoot" these deadly bubbles to kill prey, jackhammer into rock to create burrows or protect said burrows from other, jealous shrimp.
They have no need for a fancy holster or to stock up on ammo — their gun is built right into their one, oversized snapper claw that can grow to be half the size of their tiny body.
The monstrous sound isn't actually caused by the parts of the claw impacting each other. As the shrimp open their large snapper claw, water fills the small crook.
Upon closing the claw with impressive force, a plunger-like piece shoots the water out at speeds as fast as a car traveling down the highway. This creates a powerful bubble that not only kills what's in its path but creates a ridiculously loud sound when it pops.
Here are six fun facts about the pistol shrimp:. These sharp-shooting crustaceans are far from quiet — their bubbles have measured in at decibels , which is louder than a speeding bullet.
To us humans the sound isn't actually that loud, but that's due to the blast only lasting a tiny fraction of a second. When the bubble pops, it generates heat that reaches 8, degrees Fahrenheit 4, degrees Celsius , four times hotter than lava.
The heat dissipates at rapid speed so there are no lasting effects except to the unfortunate small creature that felt its burn. The powerful pistol shrimp threw an unlikely wrench into the U. Navy's defense plan during World War II.
