Cortez Rainbow Wrasse
One of the most abundant and overly curious fish we encountered along the reefs of Cabo Pulmo were the Cortez Rainbow Wrasse. The vast majority of these fish were in an initial phase of coloring, much like the one I photographed here. However, on occasion we would encounter a stunning terminal phase adult and it becomes obvious where the term rainbow is derived from (FishBase picture of Terminal Adult). However these terminal phased adults were few and far between and their behavior was extremely erratic and wary... Very difficult to photograph.
Even the initial phase adults were non-stop swimmers, poking their greedy little mouths into every nook and cranny they could find. At times we would have huge congregations of this wrasse following us, hoping we might stir up something tasty for them.
