MicroFactzzz#0053 · 🐙 Animal Chaos
This creature punches so fast it makes water flash with light
A mantis shrimp's limbs accelerate so violently they trigger cavitation — bubbles that collapse and release heat and light.
Mantis shrimp strike with their specialized limbs at an acceleration comparable to a bullet fired from a gun — one of the fastest movements in the entire animal kingdom.
The strike is so violent that the water in front of the limb momentarily boils — cavitation bubbles form, and when they collapse, they release a flash of light and a temperature close to that of the surface of the Sun, all within a fraction of a microsecond.
The resulting shockwave alone can stun or kill prey even when the limb doesn't make direct contact — a mantis shrimp sometimes effectively "fires twice": once with the strike itself, once with the pressure wave.
The impact is powerful enough that mantis shrimp kept in home aquariums are known for shattering the glass — which is why they're housed in tanks made of reinforced, thick glass or acrylic.
