Cayman Brac , one of the Cayman Islands, is located the Caribbean Sea.  Over 260 species of reef fishes have been identified during REEF Fish Surveys in Cayman Brac.

25 most common species in Cayman Brac

The following ranking is based on the results of 274  REEF Fish Surveys covering a bottom time of 364 hours and 7 minutes. (REEF Geographic Zone Report. June 3, 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.
