Olfactory sensitivity to aminoacids in the juvenile stages of the European eel Anguilla anguilla (L.)
Scanning electron micrograph observations of the olfactory mucosa from both unpigmented glass eel(GE)andpigmentedelvers(EL)of the European eel, Anguilla anguilla(L.), revealed the presence of various cell types; amongst these, the ciliated and microvillous ones are likely to possess a chcmosensory f...
