Observations on the pancreas of the marine lizard fish Saurida tumbil (Bloch)

Abstract

The pancreas in the marine lizard fish Suuridu furnbil (Bloch) encircles the pyloric region of the gastro-intestinal canal. The islets of Langerhans are ovoidal usually with a central cluster of p cells and the a cells in the periphery. In contrast to the p cells, the a cells have larger nuclei. Suuridu tumbil is heavily parasitized by cestodes, nematodes and trematodes which infect the pancreas displacing or replacing much of the tissue.
