Meet the ohana

Great barracudas swim in the waters off Hawaii

A week or so ago, I was snorkeling when I happened to glance behind me and saw I was being followed by the local barracuda ohana. Ohana is the name for family in Hawaiian and these were Great Barracudas, which sometimes congregate together in this way. I think they follow people swimming in the hope that they’re spear fishing, and might catch something which they can steal. I offered no such rewards, so they soon moved on.

I see 10 in this photo, but I counted a dozen in the water, and there might have been more. They were all what I call small barracudas, perhaps a foot to 18 inches in length. The biggest around here get to be three- to four-feet long and much bigger around.

It’s not all about looks

Reticulated Butterflyfishes are among the easiest fish to identify with their array of white spots on black, and other notable markings.

The same cannot be said for Brown Surgeonfishes. Mostly brown, with a tinge of lavender and some dull spots on the face, this is a fish that’s often overlooked. But according to my fish book, it boasts a couple of noteworthy accolades.

The first is that, back in 1993, “the biggest species of bacteria known to science had been discovered in the gut of this surgeonfish.” It notes that the bacteria was about the size of a hyphen in a newspaper article, which is a pretty good size actually.

The other distinction is that a study, by Roland and Marie-Louise Bauchot, of the brains of Hawaiian reef fishes, declared that the smartest fish on the reef is none other than the little Brown Surgeonfish.

Peppered Moray Eel

Peppered Moray Eels live in shallow waters, including tide pools and ponds. My fish book describes them as bold and active, and notes that they will even launch themselves out of the water, onto the rocks, trying to catch crabs, their primary prey.

So it’s somewhat surprising that, while I have probably seen glimpses of this eel, these are the first photos I’ve taken of one. This one was swimming along and, obligingly, continued to do so for a while, without disappearing into a crack or hole.
