Uberon Taxon note : Most fish lack intestinal glands that extend into the mucosa, Gadidae (Jacobshagen
1937) and Macrouridae (Geisterdoerfer 1973( have glands at the base of surface folds
throughout intestine - these have been called crypts, but cell types are the same
as for surface epithelium. Crypts have been described in salamander midguts (Reeder
1964) some reptiles (Luppa 1977) and some birds (Ziswiler and Farner 1972). Reptile
crypts are less developed than birds and mammals, with epithelium similar to the surface.
Avian crypts vary from those with absorprive and goblet cells to those that have cells
with basophilic granules;
