我都 fact check 多次,搵到外國 source:
Their punch is so fast it results in ‘cavitation’ bubbles. This is a super heated bubble and small flash of light, which for split seconds also generates temperates of 4,400c (which is nearly as hot as the sun) in the surrounding water.
When the bubbles collapses they cause an intense shockwave which is like a double punch and can stun, dismember or kill prey instantly – even if the mantis shrimp misses the target.
