Epsilon cell Epsilon cell Epsilon cells (ε-cells) are endocrine cells found in the Islets of Langerhans and produce the hormone ghrelin. They were discovered in mice. In human fetal pancreases, single epsilon cells scattered in primitive exocrine tissue were observed to start aggregating into clusters after gestational week 13. From gestational week 21, epsilon cells were observed around developing islets, forming an almost continuous layer at the rim of the islets. In adult pancreas samples, they remained localized on the mantle of the islets in different amounts. Production of ghrelin with insulin, glucagon, or somatostatin was not detected during development.

Beatrice Islets about 7500 years ago when sea levels reached current levels. The islets are composed of sand and sandgrit. The islets is part of a drying spit at low water which falls to a depth of within about to the west. As of 1987 and again in 1996, the Beatrice Islets were reported as having no vegetation as a result of an exercise to remove the infestation of South African boxthorn. While sources dated 1987 and 1996 do not explicitly list fauna for Beatrice Islets, it is likely that fauna species which are exclusively birds reported as being present on The
