Diver's Notes

Wolf Island is larger than Darwin, and has several dive sites nearby. We stuck to two familiar ones: Landslide and Shark Bay. These, we were told, had the most abundance of marine life. Another nearby, called The Cave, was an easy dive but harbored less sea life. The other was at Elephant Rock and could be quite challenging, without much chance of reward that we wouldn't otherwise get at the first two sites. Thus, we stayed put for our last two dives at Wolf Island. I'm starting to pick out stone scorpionfish a little easier. At least they seem to be more abundant: perhaps a gentle reminder not to get too comfortable on the rocks. It's hard to get tired of seeing hammerheads and galapagos sharks, and even if you do, there are so many things to discover among the boulders. But this morning we wouldn't have to look long for something new: shortly into our dive a pod of dolphins swam by, out over the ledge. Too quick to follow or meet: they appeared to be on a mission to somewhere. Later, this or another pod swam back by in the opposite direction--mission accomplished, I presume. Underneath, I noticed a green coral of some sort, with stubby vase-like tubes fringed with pale green or yellow. Maybe I hadn't noticed them before, or maybe this time they struck me as something worth studying. Once you get over the shock and awe of nearby sharks and larger pelagic animals, you start to notice all sorts of creatures. Nonetheless, it was hard not to take notice of the abundance of hammerheads on this dive: perhaps the largest school we have seen to date swam by just below us. The temperature had dropped a few degrees and the water was clearer than when we were here two days ago. That may have been a factor in the presence of larger schools. During one of our first briefings, we were told about barracudas. I don't recall if I had seen any previously or not, but on this dive, as we swam out over the blue and away from the wall, I came upon a small school of them. I noticed they were largely different than the ones we commonly see back home and in the Caribbean. These were much smaller: two- to three-feet in length and over all had a less aggresive look to them. Like their cousins, they are long and slender, with long jaws, but did not expose their teeth as do the Atlantic variety. Later I learned that these are "pelican barracuda" (Sphyraena idiastes), indeed a different species than the more familiar great barracuda that I am used to seeing.
