Coral Spawn & Night Dive - Sept. 27 & 28, 2002

Below are images from two consecutive night dives at the Small Wall / ReefCam Reef dive site on Bonaire, on September 27th and 28th, 2002. All images taken with a Sony PC-100 miniDV camera in a Light & Motion Mako housing with video lights either using the still image capture feature of the camera or captured off digital video (hence the occasionally grainy quality and small size of the images).

I have created an animated (4MB - large!) GIF of a Boulder Star Coral (Montastraea annularis) spawning. You can find that animation here: BoulderStarCoralSpawn.html

Photos & Images

At left is a boulder star coral just after all the egg packets have been released by the polyps in the area.
Here is a baby Blue Tang in his "pyjamas" - found in just three feet of water.
Here is the same species as the baby directly above, but as an adult.
Arrow crab taking a stroll
As I was finishing my dive in the shallows (2-3 feet depth, just a few feet from shore) I came across what appeared to be a leaf, but something wasn't quite right. It turned out to be a fish letting the surge wash it back and forth just above the bottom. I had never seen this fish before, but located it in my reference books as a Black Fin Cardinal Fish.
Brittle Star waiting for the coral to spawn so he can participate in a spawn smorgasbord
A different species of Brittle Star out for some food as well.
At night, many fish change their colors. This Cardinalfish (sub-species unknown) is no exception.
Coral Banded Shrimp come out at night too.
A Creole Wrasse takes a nap under a coral head.
A Goat Fish in his jammies
Look carefully. Can you see the Peppermint goby in his see-through jammies on this brain coral (which appeared ready to spawn too, but I didn't see it happen)?
Squirrel fish are light shy, so during the day they are in the dark spaces under coral heads, and at night they venture forth into the open.
At night, parrotfish (I believe this is a Stoplight Parrot) change colors and "spit" out a sticky cocoon to stay safe while they sleep. They also change their colors to better blend into the scenary (keeping in mind that predator fish are somewhat color blind, and are attracted more to high contrast and motion).
While you may never see these by day, at night Teardrop crabs are more prevalent as they forage for food.
At one point during the dive I came across a school (or herd?) of over a dozen Trumpetfish, almost all (except for this one) hanging head down in amongst the software corals as a form of camouflage.

That's all for these dives!
