A light microscopic study of the endocrine pancreas in some myxinoids has revealed a striking difference in the occurrence of follicles. Islet tissue follicles are regularly occurring and also abundant in Myxine glutinosa , but are sparse or absent in Eptatretus burgeri and Eptatretus stouti. Whether this is caused by a decreased need for insulin in Myxine glutinosa is discussed but remains an open question.
