Imagine that you worked out, but only one of your arms. Imagine you pumped so much iron and drank down so many protein shakes that your one muscular arm grew almost as large as your whole body, and you could clap so loud that the people around you literally died.
You’ve just successfully imagined being the Pistol Shrimp.
The pistol shrimp’s arm has a goddamn cannon built into it. To go hunting, the shrimp picks a concealed spot, like a burrow, a bit of coral or a little underwater grassy knoll, and waits, antennae sensing the water for prey.
When something edible swims too close, the shrimp pulls the hammer on its claw back, “loading” it.
That claw then snaps shut, creating a blast of sound. The water ahead of the shrimp briefly spikes to 5000°C, or the temperature of the fucking sun. There’s even a flash of light, caused by the sheer force of the collapsing vacuum in the water.
The prey is hammered by the shockwave, and stunned or killed. After that, the shrimp can drag them into its sniper nest and munch at its leisure.
What’s more, they can’t be disarmed. If a pistol shrimp loses its cannon-arm, presumably to the oceanic equivalent of Jason Bourne, it will regenerate as a normal claw – while its other arm grows to monstrous size and becomes a cannon arm.
Try to take the gun away, and it just switches hands.
Pistol Shrimp are found all over the world, with members blasting their way across tropical waters, up into temperate coasts and in freshwater caves. However, these lunatic sniper shrimp are drifting further North than ever before – a pair were found by an English fisherman off the coast of the UK this year, and they are increasingly being fished up outside their usual ranges, hopefully by fishermen in bomb-proof blast suits.
The only explanation is that they are being pushed North by climate change, and while the shrimps themselves are fine with this, the fish and crustacean species already in their new shooting gallery aren’t – any invasive predator is bad news, and one with such an unstoppable hunting strategy is even worse.
What’s more, some of them are even eusocial, like bees, wasps and ants. The Synalpheus genus, which lives in sea sponges, forms colonies of a single “Queen” female, hundreds of workers, and hundreds of soldiers, all armed with the pistol shrimp’s shockwave cannon.
You know what happens next.
Little underwater trenches and little underwater artillery emplacements.
Be right back, I just had a great idea for a SyFy Original script.
