My second dive at Sharks Cove. This time I smartened up and asked to borrow the boots and fins that the divemaster originally offered me. This made the second walk to the ocean much easier and quicker.
On this dive we went to the right side of Sharks Cove where all of the lava tubes are. The lava tubes here are just tunnels in the lava rock that divers can swim through. It got pretty tight in some of the lava tubes and there was never any real danger of getting stuck but I wouldn't want to see a claustrophobic trying this.
We did 3 or 4 of these lava tubes before heading to shore. On our way back I noticed a small hermit crab walking along the reef. It's not too often I see these guys actually up and walking around. I managed to get a decent closeup of him before moving on.
Also on the way back I noticed a ton of activity on one of the reefs. There was a feeding frenzy going on on a reef near the surface (you can see some snorkelers). I have no idea what exactly what they were feeding on but it was a pretty impressive sight.
