Goblet cells in the intestine of shi drum Umbrina cirrosa showed the presence of glycoconjugates particularly rich in fucose and N‐acetylglucosamine residues. They displayed also sialic acid linked to galactosyl(β1→3)N‐acetylgalactosamine and to galactosyl(β1→4)N‐acetylglucosamine. All the nine horseradish peroxidase‐conjugated lectins employed with the only exception of GSA II marked the enterocytes supranuclear region and the cell coat; the cell coat showed a more intense reactivity toward the different lectins, particularly enhanced with the use of fucosyl specific lectins.
