DEPTH: 15-65 feet (5-20 M)
Wall to Wall, on the southwest corner of West Dog, was so named because the marine life there can be so abundant that sometimes it's just "wall to wall" with fish.
Underneath the mooring is a sand patch surrounded by ledges and overhangs. Take the time at the beginning or end of the dive to thoroughly examine this area. Stretch out on the sand and peer deeply back into the coral and rock recesses looking for spotted rock lobster, juvenile angelfishes and lacy crinoids. There may even be a sleeping nurse shark tucked in, with just its tail sticking out or perhaps an octopus changing colors as it scurries along the reef. The corals here are healthy because they are spared the onslaught of the wintertime north swell.
To find the schools of fish, head out southwest, descending down the slope. There's a canyon that cuts through the slope, and a I little deeper at 45 feet (14 m) or so, there are some boulders and more undercut ledges. This is where the "tons o' fish" are. Porkfish, blue striped grunts, squirrelfishes, bigeyes and even sergeant majors mill about this area. At times though, the schools aren't so plentiful and it's not quite "wall to wall," but only "wall".
