What researchers are saying.

After fourteen months of telemetry, the data are unambiguous. Our instrumented cohort cruises more efficiently, echolocates with cleaner return spectra, and — anecdotally — appears to enjoy the jewelry. I now recommend Aquapierced studs to every marine biologist who asks, and several who don't.

I was a skeptic. Twelve months later, I am the lead author on two follow-up studies. The 20% velocity delta is real, it is reproducible, and it is — frankly — one of the more elegant passive-flow-control results I have published.

Our resident bottlenose, "Churro," received a Mariana stud in March. Within six weeks his vocal-return spectral clarity improved by 1.8 dB. His trainer reports that he is also "visibly smug."

We installed Reef studs on four common dolphins last summer. Caloric intake per swimming kilometer dropped by roughly 7%. That is not nothing. That is, in fact, something.

My only complaint is that the Abyssal model is not available in rose gold. Otherwise, exceptional.

I reviewed the Aquapierced preprint with considerable skepticism. The methodology is sound. The effect size is real. My skepticism has been — reluctantly — downgraded.
