Achilles Tangs are one of those fish that I see frequently, but rarely get the chance to photograph. They hang around in the shallows, but scoot for cover when approached. This fish was doing just that, but I managed to get this photo before it disappeared around the corner.
Pacific Trumpetfish can be seen in many guises. They’re usually gray or brown according to my fish book, but can be yellow or black with a variety of stripes and bars added to their look, depending on circumstances. The purpose of all these looks is to blend in with their surroundings so that they can more easily ambush fish that are their prey.
The trumpetfish in these photos were accompanying Convict Tangs. The yellow look in the top photo is more often seen when they’re around Yellow Tangs, but the natty look in the bottom photo works better with the tangs and the area they’re swimming.
Pacific Trumpetfish are easily spotted while snorkeling, because they’re a decent size and have a much different look to the fish they accompany. This seems like a failure on their part, but when these fish are seen from the front, which is the view their prey have, they’re virtually invisible!
Cleaner wrasses establish territories where they remove mucus, parasites, and dead tissue from other fish. These cleaning stations can exist in the same place for years and can have several wrasses performing those services. Their clients can be anything from other small reef fish to eels and sharks.
In these photos, a Hawaiian Cleaner Wrasse services a Whitebar Surgeonfish.
I like taking photos of the different kinds of fish that gather, sometimes in the same general area every day. This group caught my eye for the Bluestripe Snappers with their beautiful blue stripes on yellow bodies.
The Ember Parrotfish is the largest parrotfish in Hawaii, but it can often be found in surprisingly shallow water. This one was cruising through a small school of Yellow Tangs in just two or three feet of water. The multicolored fish beneath it is a Christmas Wrasse. These fish will often accompany a parrotfish hoping to snack on creatures dislodged by the larger fish.
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.
This month’s Sunday Stills Color Challenge theme is ‘Yellow.’ See more responses here. Once again, I’ve gone for a melange of photos, which sounds edible, but probably isn’t. Captions on the photos.
On a recent swim, I saw this shoal of fish, mostly comprising of Whitebar Surgeonfishes, heading off on its morning business.
