I spotted this small Pacific Day Octopus on the move and it quickly headed for a spot to settle down. The place it chose was just below a head of coral, which was occupied by an Arc-Eye Hawkfish. The hawkfish didn’t move, but didn’t look happy with its new neighbor.
A cheerful-looking Saddle Wrasse swims over a patch of coral. One side of the coral head has long since died, but the other looks quite healthy and hosts an Arc-eye Hawkfish.
Stocky Hawkfish markings appear symmetrical, but aren’t quite. However, they do an excellent job of helping the fish to blend in as it waits, motionless, to snag passing prey. This fish was more patient than most. There was a swell running and it kept swishing me back and forth in front of the stoic fish, which was sheltered from the waves, and also wedged in with its pectoral fins.

A Stocky Hawkfish waits in a crack with a Rock-Boring Urchin, as shifting light plays across the water.
These are a couple of fish that spend a good deal of their time sitting, stationary, on coral or rocks. The similarity ends there.
The hawkfish is a predator, waiting for small fish or crustaceans to come within range. The blenny feeds solely on living coral. And while this blenny is probably an adult at about 6 inches long, the hawkfish can grow to twice that size.
How many Arc-eye Hawkfishes can you fit in a head of Cauliflower Coral? I count six here, though there could be more, and who knows what else besides. Corals like this offer vital shelter for small fish and other creatures seeking to avoid the many predators out hunting.
A pair of Fourspot Butterflyfishes disturbed a pair of Arc-eye Hawkfishes perched in a head of Cauliflower Coral, as they often do. The coral head is doing OK, but areas of it have died off, probably during one of the coral bleaching events that have happened in the past few years, where the water gets too warm.
I can get chilly fairly easily when I go swimming, but for me, it’s more distressing when the water feels oddly warm because I know this is bad news for the corals.
