In the area I usually swim, there’s a bit of a cliff with rocky parts protruding above the water. One of these, we call Viper Rock, because a very large Viper Moray Eel could often be seen in a small cave below the peak.
When the eel is not home, others sometimes take up residence. I’ve seen other eels, lobsters, and crabs in there. Yesterday, I saw this Giant Porcupinefish occupying the space. Sometimes fish will make a quick escape, but this one just watched me. It was only when I got home that I noticed, in one of the photos (not a good one alas), a small Giant Porcupinefish. So perhaps it wasn’t just this fish, but a family occupying the space.

Is it always that big & round? or does it inflate itself like a puffer fish?

That’s it’s normal size, and it can be considerably larger. It can also inflate itself to look even bigger and more difficult to swallow!

How giant is giant? It’s good that a family feel safe there

My fish book says this is the largest of all porcupinefishes, growing to about 28 inches. This one was smaller than that, no more than a foot long.
