Male guppy (Poecilia reticulata) photographs from five Trinidad locations in 2017

Photographs taken of mature male guppies in summer 2017 in 1-2 locations in each of three main drainages on Trinidad. Males were haphazardly sampled in stream reaches from 0.02-0.40 km in length, depending on the density of adult males present. Males were anesthetized in MS-222 and photographed anytime from late morning to early afternoon in partly shaded to exposed areas. A tab delimited text key to all photographs has been included as well.
