Introduction 

Anguilla  is one of the most northerly of the Leeward Islands in the Lesser Antilles. It consists of the main island of Anguilla itself, approximately 26 km (16 mi) long by 5 km (3.1 mi) wide at its widest point, together with a number of much smaller islands and cays with no permanent population. Over 165 species of reef fishes have been identified during REEF Fish Surveys in Aguilla.

The following ranking is based on the results of 102 surveys covering a bottom time of 74 hours and 56 minutes. (REEF Geographic Zone Report, May 27, 2009).  The species are ranked by the percentage of surveys in which a species was observed.  Abundance of fishes in REEF Fish Surveys are estimated using the following categories: 1- single =1 individual, 2-few = 2- 10 individuals, 3-many = 11-100 individuals, and 4-abundant > 100 individuals.  The mean numeric abundance (ranging from 1 - 4) was calculated for each species..  The mean abundance category is determined as follows: mean abundance category 0 - 1.49 = single, 1.50 - 1.99 = single-few, 2.0 - 2.49 = few, 2.5 - 2.99 = few-many, 3.0 - 3.49 = many, 3.5 -3.99 = many-abundant, and 4.0 = abundant.
