A visual survey method specifically designed for REEF volunteer data. During RDT surveys, divers swim freely throughout a dive site and record every observed fish species that can be positively identified. The search for fishes begins as soon as the diver enters the water. The goal is to find as many species as possible so divers are encouraged to look under ledges and up in the water column. At the conclusion of each survey, each recorded species is assigned one of four abundance categories based on about how many were seen throughout the dive (single (1); few (2-10), many (11-100), and abundant (>100)).

A warm, swift, ocean current that flows northward between Cuba and the Yucatán peninsula, moves into the Gulf of Mexico, loops clockwise in the eastern Gulf before exiting east into the Atlantic Ocean through the Florida Straits. It is part of the western boundary current system of the North Atlantic subtropical gyre and may extend to great depths. An eddy, or Loop Current ring, separates from the Loop Current and may drift slowly westward into the central and western Gulf of Mexico.

Agnathans are the most primitive and ancient of the vertebrates. As the name "Agnatha" implies, they lack jaws. Paired fins are also generally absent, and the the adult retains the notochord. The skeleton is cartilaginous. The agnathans include the lampreys and hagfishes.
