FIGURE 1.

Two hybrid crosses from two lake populations on San Salvador Island, Bahamas. Lab‐reared molluscivore (C. brontotheroides) x scale‐eater (C. desquamator) crosses from Little Lake (a, c) and Crescent Pond (b, d). (e) Inset Caribbean map shows the location of San Salvador Island with collection sites for each cross indicated on the larger island map. Laboratory colonies were raised over multiple generations in a common garden laboratory environment, indicating that the differences in trophic morphology shown have a genetic basis. Representative photograph of Little Lake C. desquamator is from a closely connected lake population due to the lack of high resolution photographs of lab‐reared females from Little Lake.
