View of the reefs off the coast of Key Largo
The individual patch reefs are visible in this shot.
A territorial terminal phase (TP) male patrolling his spawning territory during the spawning period.
A non-territorial TP male on the same reef during the spawning period. He only tries to spawn with females when the territorial TP male is away.
Dianna May (IRSC), April Lamb (NCSU), and Itze Cabral (IRSC) following and recording the behavior of a very fast and evasive territorial TP male.
Hard to spot the TP male Itze is watching!
A gravid (full of eggs) female during the spawning period.
John watching a TP male at his spawning site. The females below are hard to spot.

A calmer day finally permitted us to go to the reefs.

Sexing, measuring, and tagging fish from a patch reef. We release them back onto the reef and record their behaviors to determine which females are changing sex.

A beautiful view of this reef.
Me and Sophie Austin (here a Sophomore during the 2012 field work season) loading the boat with gear in preparation for heading out to the reefs.
On days we are catching females to set up sex change experiments, we head out to the reefs during sunrise in order to catch the fish early in the morning before the late morning/early afternoon spawning period.
Some days couldn’t be more perfect for catching and observing bluehead wrasses.
