Life on the Big Island of Hawaii
There are a fair number of predatory fish in Hawaii, that eat other, smaller fish. These fish have a variety of hunting strategies, everything from ambush to outpacing their prey. Some fish team up with other predators.
Fish that employ this latter strategy include various goatfish and bluefin trevallies. These fish often accompany each other on hunts, but either or both can also be seen with other predators including eels and octopuses.
I followed this bluefin trevally and whitemouth moray eel for a few minutes and didn’t see them catch anything, but they were definitely traveling together. If the eel hung out for a while under a ledge, as they like to do, the trevally would hang around, passing back and forth or circling the spot.
This tendency is actually helpful for spotting eels and particularly octopuses. Several times I’ve seen a goatfish or two milling around a rock for no apparent reason, so I’ve waited and watched. Sure enough an eel pops its head out or, better still, the rock turns out, on careful examination, to be mostly octopus.
There you go, an actual useful tip for snorkelers.
I saw this little outrigger sailing canoe off the North Kohala coast. The two men had obviously been fishing, possibly still were, but though the canoe wasn’t too far out, I couldn’t figure out which way they were headed. I guess they must have made it safely to shore since I didn’t see anything in the news about missing mariners.
Morning glory vines spread through, what I think is sea purslane, at Pu’uhonua o Hōnaunau National Historical Park.

Gold dust day geckos have a lot of character. They’re largely unperturbed by human presence, often just returning the gaze of the big-headed creature looking at them. If they do feel threatened, they’ll disappear in an instant, usually just running off, but sometimes hurling themselves into space before sticking to whatever surface they were aiming for.
I found this gecko on a bird of paradise flower. I like the cheeky grin above, then the look of contemplation, and finally the reward.
