Acute Halfbeaks swim just below the surface of the water, often in schools. It’s not unusual to encounter them flashing by, which can be a little disconcerting, especially when the group circles back around. They’re not something to worry about during the day, but at night needlefishes in general can be excited by lights in and on the water, and there have been many instances of people being speared by those long, sharp beaks, some fatally.

I will be sure not to snorkel at night! I have seen many of those in Oahu when snorkeling. 😳

They’re very common here, but I never worry about them since I only swim when it’s light.

Great photo Graham. The light above and onto the fish is so good. I would be circumspect about them as well. They do look dangerous

It’s only at night that people need to be careful. It’s the lights that excite them and their chasing of prey attracted by those lights. They don’t attack people, but they do collide with them if they are in the way!

They’re a good sight. I could understand if you missed them, though, with reflections skiing through.

I like seeing them, especially when they catch the light right.

I don’t worry about them about them because I don’t get in the water at night. during the day they just putter around like the rest of us!

They certainly can, but it’s really only an issue for those on or in the water at night. It’s the lights that get them excited. They don’t attack people, but in chasing things attracted by the lights they can run into people with their pointy beaks.
