Little fish

A shoal of small fish stretch away into the distance. I think these are juveniles but I’m not sure of which fish. They’re small and silvery and zip around in a harmonious way, changing direction as if connected by invisible wires.

Posted in response to Becky’s July Squares challenge theme of ‘Perspective.’ See more responses here.

Stareye parrotfish

The magenta lines around the eye of this fish identify it as a supermale stareye parrotfish. Parrotfish have initial and terminal phases. Most adults remain in the initial phase throughout their lives as either males or females, though some parrotfish are all females.

Terminal phase parrotfish are called supermales. These are female initial phase fish which have reversed their sex. They will fertilize most of the eggs laid by initial phase females in their territories. When one of these supermales dies, another initial phase female will reverse sex and take its place.

Big and small bluespine unicornfish

Adult bluespine unicornfish, such as the one above, are liberally trimmed with blue on their fins, spines, and tail streamers. They also have a horn jutting from their brows. Juveniles are also tinged with blue, but while they have blue spines, they don’t yet have tail streamers and they don’t have a horn. Once they grow a horn, their cuteness will disappear and they will acquire the grumpy look of most unicornfish.

Yellow tang and little fish

Shoals of yellow tang are the most visible fish on the reefs. Their bright yellow color means that they’re often easily seen from shore. The smaller silvery fish are juveniles, though I don’t know which kind of fish they are. But it’s fun to see them darting around in the shallows and, as seen in nature documentaries on TV, turning en masse from one direction to another when I approach.

Abstracts: Flowery flounder

Time for an eye test as in spot the flowery flounder. I don’t think this one is too hard. Not like the last flounder I saw which settled on a sandy bottom, churned up a bunch of sand, and disappeared beneath it leaving only a tiny, inconspicuous bit of tail identifying where it was.

Yesterday’s swim

A small shoal of convict tang feeding.
I think this is a spotted coral blenny on a head of purple cauliflower coral, and possibly a small trumpetfish.

This is a second response to this week’s Sunday Stills challenge theme of ‘Waterworld.’ (See more responses here.) Yesterday, I posted about the movie Waterworld. Today, it’s a probably more expected response.

These are photos I took during my swim yesterday. Visibility in the water was patchy with some good areas and some not so good. I didn’t see anything startling, though the mackerel shads aren’t a common sight. Last time I saw such a shoal there was a great barracuda lurking on the other side. I looked around and, sure enough, there was another one looking interested as it cruised low down, too low for a decent photo.

The other oddity was in the photo at left. I saw what I think is a spotted coral blenny on this patch of cauliflower coral, and snapped a quick photo before it took off. But it was only when I processed the photos that I saw something else, to the left and slightly below the blenny. I think it’s a small trumpetfish, but it could be something else. A lot of small fish and other creatures hide in coral heads so I must pay more attention from here on.

In short, it was a fairly typical swim.

Little fish enjoy the comparative safety of the shallow water in the surge zone.
On the left, a fourspot butterflyfish and a cushion star. On the right, black triggerfish are cleaned by a Hawaiian cleaner wrasse.
Just before getting out I saw this small Pacific trumpetfish with goldring surgeonfishes.
