Puffer Fish Blow Fish

Updated: Nov 10, 2020

Puffer fish are named for their ability to expand their stomachs, swallowing huge amounts of water (or sometimes air) very quickly, causing their bodies to inflate to many times their normal size as a defense against predators. Most species also have spines. Those of most puffers are hidden until they inflate, while the porcupine fish have external spines that are always visible. Either way, when the fish inflates, it turns itself into a spiky and unappetizing ball that is not easily swallowed by a predator. We these guys in Playa Huevos when we are snorkeling. So many sea creatures to see!!

We see these on some of our tours.
