Small marine worm emits one of the ocean’s loudest noises

A small worm emits one of the loudest noises emitted by animals in the oceans, so strong that it could break even small glass vessels. The study analyzed the Leocratides kimuraorum, marine worms a little less than three cm long discovered for the first time in 2017.

These worms, which live in the small grooves of the hexattellellid sponges, were identified off the coast of Japan. But only when they were brought to the laboratory did the researchers discover the strangest feature related to these small animals. When they fight each other, they strangely contract their bodies by jumping “head down” towards the enemy.

This specific movement is the cause of the emission of a loud popping sound, similar to the noise emitted when ripping off the champagne. The researchers detected this municipality through specific underwater microphones. These are not the only small marine animals that produce such loud noises: even shrimps usually “snap” with their bodies but do so by quickly closing their claws.

The Leocratides kimuraorum, on the other hand, have no hard part because they boast a completely soft body. They simply manage to generate this loud noise through very high pressure by twisting the body which, at the simple contraction of the muscles, emits noise.
