These pouches are the "gastric caeca" occasionally mentioned in the literature: however, their tissue lacks a differentiated luminal epithelium relative to the anterior midgut, nor do they harbor large quantities of symbiotic microbes, and thus may not be considered "true" caeca (Beadle 1972, Shelomi et al.
