RESUMO
The Neotropical region has the highest freshwater sponge diversity in the world, with the presence of species of the families Metaniidae, Potamolepidae, and Spongillidae. Due to the remarkable lipid diversity in these organisms, this study aimed to characterize the sterols and volatile compounds of the sponge Trochospongilla paulula collected in the Tapajós River. Seven volatile compounds were identified, with the long-chain alcohols tetradecanol, pentadecanol, and hexadecanol representing 51.65% of this fraction. Cholesterol is the major sterol species, as reported for other species of the family Spongillidae; however, T. paulula may be distinguished by a chromatographic profile of its sterols.
