Fig. 7

Histochemical composition of COM, PAR and PER poison glands. Regardless of the species studied, all glands secrete proteins, acid glycoconjugates (mainly PAR glands), lipids and biogenic amines. Note the similarity in composition of the secretion in COM and PER glands. Species: Rhinella marina (first and third rows) and Rhinella icterica (second and fourth rows). Histochemical methods: bromophenol blue (first row), alcian blue pH 2.5 (second row), Sudan black (third row) and modified Masson-Fontana (fourth row)
