Once it feels the movement, it inches out of its hiding place and releases the shot which stuns or kills the prey. This theory was recently discovered, thanks to the use of a system that allows recording at high speed, and another one of acoustic detection, which provides tools for studying the behavior of this species in its natural habitat.

The bubble that is created serves the purpose of stunning a prey. Like, really loud. A joint allows the "hammer" part to move backward into a right-angled position. Simulations show that during claw closure, a high velocity jet forms, inducing vortex roll-up around it. The flash is likely a byproduct of the insane pressure changes, temperature changes, and sonic waves emitted during the bubble implosion [3]. This is called sonic hunting a way to stun and kill prey without ever making direct physical contact and the source sound generated can get up to 210 decibels, which is louder than a gunshot. 10. Sorry, but we failed to add you to the list. What is Our Oceans Role in the Transition to Clean Energy? Necessary cookies are absolutely essential for the website to function properly.
