Uberon Homology note : Most adult amphibians have a tongue, as do all known reptiles, birds and mammals.
Thus it is likely that the tongue appeared with the establishment of tetrapods and
this structure seems to be related, to some extant, to the terrestrial lifestyle.[well
established][VHOG];
Uberon Taxon note : Many species of fish have small folds at the base of their mouths that might informally
be called tongues, but they lack a muscular structure like the true tongues found
in most tetrapods;
