There’s something captivating about this two-minute clip, which displays human interaction with marine life at its best.

A porcupinefish (or “blowfish”) is possibly fatally trapped in a net in Chaloklum Bay, Thailand. A pair of snorkelers happen upon the little pufferfish and meticulously work to free him.

Meanwhile, a second fish hovers nearby, waiting attentively.

The Diodon liturosus is, in fact, a black-blotched porcupinefish, which have the ability to swallow water and raise their spines to make themselves look bigger and fiercer.

They also harbor in their bodies a neurotoxin that contributes to self-defense, according to a report on the video by WNPR News.
