Shoots! So you wanna know about the Hawaii state fish humuhumunukunukuapua'a? Yeah, I know - that's a mouthful. But trust me, once you spot one of these little characters while snorkeling Kauai's reefs, you'll understand why we gave it such an epic name. I've been swimming with these guys my whole life, and they never stop making me smile 🐟
Let me break down everything you need to know about Hawaii's official state fish - from how to actually say that name, to where you can spot them around Kauai, to why ancient Hawaiians loved them so much.
Okay, first things first. The name looks scary, but it's actually pretty simple once you break it down. Here's how I teach people:
Hoo-moo-hoo-moo-noo-koo-noo-koo-ah-poo-AH-ah
Say it slow at first, then speed it up. The trick is to remember there are only a few sounds: "humu" (twice), "nuku" (twice), and "apua'a" at the end.
What does it actually mean?
So literally, it means "triggerfish with a snout like a pig." And once you see one up close, you'll totally get it - they have this adorable pig-like snout they use to munch on reef invertebrates 🐷
Most locals just call it "humuhumu" for short. No worries if you can't nail the full name on your first try!
The humuhumunukunukuapua'a (Rhinecanthus rectangulus) officially became Hawaii's state fish in 1985, though the designation actually expired in 1990. But here's the cool part - it was so beloved that the state legislature made it permanent again in 2006. Can't keep a good fish down, yeah? 🤙
What makes them special:
I love watching these guys because they've got personality. They're territorial, feisty, and make this grunting sound when they're annoyed - seriously sounds like a little pig! Ancient Hawaiians noticed this too, which is how they got their name.
The humuhumunukunukuapua'a wasn't just some random fish to ancient Hawaiians - it had real cultural significance. Let me share what I've learned from kupuna (elders) over the years:
