HISTOQUANTITATIVE ASPECTS OF PYLORIC CECA OF SOME TELEOSTS WITH DIFFERENT DIETARY HABITS

The morphology of the pyloric caeca of some teleosts is described in t his study. The morphometry was performed by using a semiautomatic syst em of image analysis. The morphology of the muscular layer of the caec a and the number of goblet cells present in the villi were evaluated i n some groups of Mugil auratus (Risso), an omnivorous, limnivorous and nectonic species and of Scorpaena notata (Rafinesque). In our experie nce quantitative microscopy is a highly sensitive and efficient method for morphologic characterization of some structures of the pyloric ca eca.
