A Pacific Trumpetfish drifts in the water as a couple of Yellow Tangs pass by. Trumpetfishes often hang vertically, head down waiting to snag a meal. They also change color and markings to blend in with other fish, hoping to sneak up on prey.
Trumpetfishes looks easy to spot, but they propel themselves with dorsal and anal fins set far back on the body where they’re not seen by potential prey and, from the front, which is where its prey is, they’re very hard to see.
The top photo shows a Flowery Flounder resting on a patch of sandy sea floor. These fish blend in so well they’re almost impossible to spot. The trick is to spot them on the move (second photo). In motion, they’re quite distinctive with their undulating movement, especially if the pectoral fin is raised as in this photo.
The third photo shows the fish just as it landed on the sand to begin its very fast process of blending in.
The appearance of Undulated Moray Eels can be quite varied. The yellow-green head is a common feature, and this black and white patterning is probably its most attractive look. They are, however, considered one of the nastier eels in the area and not to be messed with.
The ring around the eyes of these fish, which gives them their name, also gives them a look of perpetual surprise.
The Hawaiian Whitespotted Toby is a small pufferfish that’s endemic to Hawaii. Like many small fish, and juveniles of larger fish, they will use the quills of sea urchins to shelter from predators. Not that tobies need too much help. When attacked they inflate themselves like a balloon, making them hard to swallow. In addition, this toby secretes a nasty skin toxin which will deter most predators.

I just liked the expression of this endemic Hawaiian Dascyllus!
I saw this Fivestripe Wrasse just before I got out of the water recently. This one seemed a little redder than the ones I usually see, which have magenta markings, though I don’t see them that often as they’re not especially common.
