This week’s Friendly Friday challenge theme is ‘Morning Rituals.’ See more responses here.
Most mornings, I try to get in the water, as conditions and schedules allow. Morning is the best time for snorkeling as the water is usually calmer before the wind picks up as the day wears on. Visibility can vary from day to day and it can help to check surf reports to see if there are any swells moving in. But calm water doesn’t guarantee good visibility just as swells don’t always mean bad visibility. There’s only one way to be sure and that’s to jump in.
My favorite thing about snorkeling is that every day is different and I never know what I’ll see. Going to the same spot means I become familiar with some of the regulars, but there are always transient creatures passing through including rays and dolphins. And while those big creatures are great to encounter, it’s equally interesting to watch the activities of smaller fish and marine invertebrates.
It’s a rare day indeed that I don’t emerge prattling on about something I saw while I was in the water. And on those rare days, well, I’ve still had a good swim to set me up for the day ahead.
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.
Two Step is a popular snorkeling spot, next door to Pu’uhonua o Hōnaunau National Historical Park, otherwise known as Place of Refuge. It gets its name from one of the entry points to the water, where two flat lava ledges make it easy to get in and out. Well, fairly easy; there’s usually a crowd gathered around the steps so it can be a bit of a scrum. Also, small sea urchins sometimes lurk in hollows in the steps.
Once it the water, there’s room to roam. I like to swim the length of the bay and out a little bit, to where I can look down the coral slopes leading to the sandy floor of the bay.

This is a typical pose for an arc-eye hawkfish, keeping very still as it nestles in a head of cauliflower coral. But the coral is not well. This patch is mostly bleached. The causes of coral bleaching include warmer than normal water temperatures, pollution, and sunscreens containing coral-killing ingredients.
Because of this third factor, Hawaii has passed a bill which will ban the sale of sunscreens containing oxybenzone and octinoxate. This law goes into effect January 1, 2021. While this will help, it won’t do anything to keep harmful chemicals out of water runoff, and it won’t do anything to prevent the warming of the Pacific Ocean.
Last fall, we had a coral bleaching event here because of warmer ocean temperatures. It wasn’t as bad as feared, but still did damage to corals that were just recovering from previous bleaching events. There are one or two snorkeling sites here that I don’t visit anymore because the state of the coral is just too depressing. I’d like to think that this degradation can be reversed but, honestly, I’m not optimistic about that.
Back in the fall of 2014, Hawaiian waters experienced temperatures up to 86°F. This very warm water resulted in a major coral bleaching event statewide. Since that time, water temperatures have been in a more normal range and the coral has stabilized and even shown signs of recovery in places.
In August of this year, the National Oceanic and Atmospheric Administration (NOAA) issued a warning that another major bleaching event was likely to happen this fall. Last month, NOAA reported that bleaching was already occurring. And I’ve noticed that the water does seem warmer, sometimes disturbingly so.
Because of the bleaching threat, I’ve been looking at the coral when I go snorkeling. There are a few very white patches, but by and large it doesn’t look too bad. This patch of purple coral still looked quite healthy and was host to a saddle wrasse (lower photo) and three unidentified fish (above).
A little snapshot of things tucked into the rocks along the Big Island. There’s a red pencil urchin and blue-black urchin, a patch of cauliflower coral, and a cowry, probably a reticulated cowry. And if you look closely, there’s a bright-eyed damselfish swimming between the coral and red pencil urchin.
Whitemouth moray eels can squeeze into the tightest spots on the reef and are often seen with just the head sticking out. They’re easy to identify with their bright white mouths, which they’re constantly opening and closing. While this activity looks somewhat menacing, they’re actually forcing water over their gills in order to breathe. That’s not to say that, if you waggle your finger in the face of an eel, it won’t bite it off so, as with most creatures in the water, it’s best to keep at a reasonable distance and be respectful of them.
