Abstract
Many teleost embryos produce an enzyme within specialized glands, which facilitate hatching. The enzyme attacks the chorion which becomes so weak that it may be ruptured easily by a blow of the tail. The embryos of Brachydanio rerio, Danio malabaricus, Moenkhausia oligolepis and Barbus schuberti show some morphological differences in the distribution of the hatching gland cells. More specificity can be found in the ultrastructure of hatching gland cells, which are loaded with enzyme granules prior to hatching. In all four species the nucleus is located near the basis of the cell. The hatching enzyme is contained within granules, which arise from the Golgi body.Keywords
