Lipogramma trilineata, the three-lined basslet, is a species of ray-finned fish from the family Grammatidae. It is found in the western Atlantic Ocean from the waters off southeastern Florida south through the Bahamas into the Gulf of Mexico and the Caribbean Sea as well as the coasts of Central and South America from Quintana Roo, Mexico to Nicaragua, and the seas off Cartagena and those off Venezuela at Curaçao and Bonaire. It occurs underneath rocky and coral ledges as well as occurring in deep reefs and on the outer wall at depths ranging from 22-69 m. Its range has been invaded by lionfish, an invasive species in the western Atlantic, which prey on a variety of fish species smaller than 15 cm which means that both adults and juveniles L. trineata are likely prey of lionfish.
