- ozfive 3y agoAll I want to know is, can you keep them in fish tanks without the glass shattering?
- jareklupinski 3y agosure, as long as you use bulletproof glass :)
- xrd 3y agoTampa Bay is having a lot of problems with noise (https://www.npr.org/2024/02/01/1228286349/south-tampa-mystery-where-is-the-sound-coming-from-neighbors-investigate https://www.npr.org/2024/02/01/1228286349/south-tampa-myster...) that none of the neighbors can figure out. Some speculate on a party boat with speakers. Some are speculating is it the black drum fish (https://en.wikipedia.org/wiki/Black_drum https://en.wikipedia.org/wiki/Black_drum) making loud noises when mating.
- ocal5 3y agoThat’s Daft Punk - Daftendirekt, actually.
- Hortinstein 3y agoI came here hoping someone would mention this, it's really strange and for a while I had just attributed it to the Air Force base traffic or Tampa International nearby, but it keeps coming up. Always interesting to learn more

- suzzer99 3y agoMantis shrimps are show-offs. They hog all the records.
- 01HNNWZ0MV43FF 3y agoHas NIF tried mantis shrimp?
- andrewflnr 3y agoThis is the closest I found, searching for "acoustic confinement fusion". Short story: probably doesn't work. https://en.wikipedia.org/wiki/Bubble_fusion https://en.wikipedia.org/wiki/Bubble_fusion

- UncleOxidant 3y agowait, how is Dom the domino fish surviving with that mantis shrimp? Or is Dom just food for the mantis shrimp?
- msrenee 3y agoHe's just fast enough to stay away.
- decafninja 3y agoIt’s a biological plasma cannon
- WhitneyLand 3y agoSeems like very misleading science reporting. It relies on the wow factor of a 12mm fish producing a sound as loud as what many people would associate with a jet engine (>140db). - Sound levels are usually assumed to be measured 1m away. For the fish, it’s measured one body length away (inverse square law applies) - Jet engines are often measured from many meters away (again inverse square law) - The fish’s sound is pulsed and lasts only 2.5ms, while jet engine noise is continuous. - The frequency emitted by the fish “exceeds 20kHz”. The frequency range of a jet engine spans almost the entire range of human hearing. - Standing next to one might startle you a bit, the other will irreversibly damage you.
- HPsquared 3y agoAlso it's underwater. I bet if someone tried to fire a gun underwater, the pressure wave (sound) would be louder than usual.
- xoxxala 3y agoThe sound wouldn’t be noticeably louder at the source, but would travel faster (sound travels 4x faster in water than in air) and farther.

- NoPicklez 3y agoI don't think so and I don't see any mention of it being compared to a jet engine. The article compares it to a sledgehammer, ambulance siren or a gunshot. A gunshot of which is not a continuous sound. Regardless, it is impressive that a 12mm fish can produce such a loud sound regardless of whether it is continuous and/or throughout our frequency range of hearing.
- reaperman 3y agoIt really does matter how far away the sound measurement is taken. 12mm vs. 1000mm away is not trivial for this "decibel" number to make any sense, contextually. 140dB at 12mm is equivalent to 100db at 1000mm. So that's 20dB less than an "ambulance" or "jackhammer" as listed here[0]. Which definitely would make the article misleading. 0: https://noiseawareness.org/info-center/common-noise-levels/ https://noiseawareness.org/info-center/common-noise-levels/
- kdfjgbdfkjgb 3y ago"produces sounds that exceed 140 decibels" is a nonsense statement. They probably meant dBSPL.
- huimang 3y agoPedantic nitpick: it's not nonsense if the common person understands the meaning. Your average english speaker uses "decibels" to mean "dBSPL" since most people aren't aware of the other ones.
- ssl-3 3y agoIt's still nonsense and devoid of meaning, and the nonsense has nothing to do with the unit presented or any simplification of that unit. Sound pressure level measurements relate to the pressure at a point in space, and do not relate -- by themselves -- to the total sound energy being produced by a thing. I can make an SPL measurement, in air, that is ~6dB higher or lower by halving or doubling (respectively) the distance betwixt the thing making the sound and the thing measuring the sound. If a sound measures 100dB at a distance of 2 meters, then the same sound also measures 106dB at a distance of 1 meter, or 112dB at 0.5 meters, or 118dB at 0.25 meters. A difference of 18dB is a difference of nearly two orders of magnitude. The study says this fish made a sound at a level of 140dB at a measurement distance of one fish length of 12mm, in water. To compare a 140dB fish-noise that to a the SPL of a gunshot, we'd first need to measure a gunshot -- in water -- at a distance of 12mm (or extrapolate for a larger distance). And I have certainly not done this measurement myself, but I strongly suspect that the intensity of the gunshot will blow the noise of this fish out of the water in an an apples-to-apples comparison.
- paulrpotts 3y agoIt’s always disappointing to me when articles describing a sound don’t include an audio clip. Someone must have a hydrophone recording!
