Dolphins and turtles, oh my

In the water yesterday, my wife and I had already seen a small turtle, when this pod of Spinner Dolphins suddenly appeared in the somewhat hazy water. Often, dolphin pods travel fast, but are spread out, with mothers and calves bringing up the rear. This one was moving slower, but tightly bunched. I reckon there were at least 40 or 50 in the pod, and in a few minutes they had all gone by, heading south.

A dolphin encounter is always a highlight of any swim, but conditions were so nice, we carried on across the bay. When we turned to head back in, I saw two turtles, almost directly below me, swimming around in a tight circle. When one headed away, the other followed and the circling resumed. I don’t know what they were up to, but they were still doing this routine when we left them.

Angry fish

First time I’ve noticed this in downtown Hawi. That means it’s either new, or my powers of observation are continuing their steady decline! The fish doesn’t seem to be associated with any kind of business. It’s just there for decoration. Maybe that’s why it looks so angry.

Tilapia nests

When I was down at Pu’uhonua o Hōnaunau National Historical Park recently, I noticed, possibly for the first time, these circles in some of the fishponds. They are the nests of male Mozambique tilapia (Oreochromis mossambicus). The males hope to entice a female into laying her eggs in their nest, after which the male will fertilize them.

Tilapia were introduced to the fishponds to control mosquitoes, but like many such ideas, they have proved detrimental to the well-being of native species. Currently, efforts are underway to remove them from the ponds.
