Abstract

The ultrastructure of Mehlis' gland of Metamicrocotyla macracantha, a gill parasite collected from Mugil liza from Rio de Janeiro, Brazil, was studied by transmission electron microscopy. The Mehlis' gland consists of two types of secretory cells, S1 and S2, each producing a different secretory body. The S1 bodies are spherical, lamellae-like and were observed in different stages of development in the cytoplasm of these cells. The S2 bodies are spherical to ovoid with dense content, showing a crystalline structure. The cytoplasm of Mehlis' gland cells contains also free ribosomes, granular endoplasmatic reticulum and Golgi complex, characteristic organelles of secretory cells.
