Abstract: Hematopoiesis is a process that is responsible for generating sufficient number of blood cells in the circulation and in tissues. We carried out histological investigations on the hematopoietic tissues of the terrestrial slug Laevicaulis alte. Evidences for hematopoiesis reveal chiefly as heavy concentrations of hemocytes in the probable hematopoietic tissues. The intestine is lined with epithelial cells and interspersed with mucocytes. Our histological studies on the hepatopancreas show accumulations of small round basophilic hemocytes. The histology of foot reveals heavy accumulation of hemocytes. The albumen gland is composed of glandular tubules or follicles lined with columnar alls filled with droplets of non mucoid secretion. Hematopoiesis of Laevicaulis alte is a useful tool to understand its different functions like physiology, immunology and detoxification process.
