Postcard from the Reef – Reef Rose

With the appearance, size and color of a rose, the moniker Reef Rose seems to fit. In reality these are the eggs of a large nudibranch, the Spanish dancer. Not at all hard to spot, I had been finding these for years before actually seeing the parent.

I always make a point to check the egg mass closely. There is another nudibranch, a tiny parasitic nudibranch that eats the eggs of the Spanish dancer, a species unsurprisingly called the egg-eating nudibranch.

Postcard from the Reef – Pustulose Nudibranch

The most common nudibranch I find on Kohala reefs. These fellows are active in the daytime and often found in the open. They are generally found on walls, or in the many small caves that penetrate local reefs.

A Morning at Three Tables

With the south shores of Oahu denied us by rough conditions, we spent a day diving the north shore of the island. The specified rendezvous was a site known to local divers as Three Tables for a little shore diving. With an iPhone and Google Maps in hand, Deb and I drove across the island along unfamiliar roads to Oahu’s famous North Shore.

What greeted us was a pleasant surprise. A small, sandy beach fronted a very interesting cove. Parking was just above the beach, we would not need to carry the gear very far at all. The “Three Tables” were an obvious set of flat rocks just out from the beach.

There were quite a few divers already present, including a class just getting their certification. Our group just added to the party. Charles and Jeannie, who had been with us on the previous day’s aborted dive at the YO-257. Another visitor from Texas, Ray, joined us for the dive.

Leading the dive would be Gabe Scotti, the owner of Kaimana Divers. Christine would be his backup. While Gabe led off, Christine would play the caboose, riding herd on the group. It was a nice day to be diving, we chatted while setting up the gear. It was a relaxed, Hawaiian style morning.

Postcard from the Reef – Sphinx Nudibranch

From a distance it looked like another common P. varicosa, a nudibranch I see all the time on the reef. Getting closer something was different. No protuberances, no yellow, what was it? Simply a juvenile that has not developed the full colors and pattern? Not knowing what it was I proceed to take a few photos of the critter.

Hitting the books it quickly becomes apparent, it was a P. sphingus I found and photographed. A new species for me! I carefully read through the descriptions of the various dorid nudibranch found in Hawai’i again. I need to look closer, there are some lookalikes to be aware of.
