Abstract

|
|
|
Integumentary structures of the stone flounder, Karefus bicoloratus were examined by means of the light and transmission electron microscopy. Stratified epidermal layer consists of supporting cells, unicellular glands and granular cells. The epidermal layer could be classified into superficial, intermediated and basal layer by morphology and structure of the supporting cells . The cytoplasm of supporting cells is divided into cortex and medullar part. In the cortex microfilaments are well developed. Mucous cells of unicellular gland were observed in the superficial and intermediated layer of the epidermis. The mucous materials were identified as glycoprotein of neutral and carboxylated mucosubstance by histochemical methods. Club cell has well developed smooth endoplasmic reticula and Golgi complex in the cytoplasm. Granular cells were observed in the intermediated and basal layer, and the cytoplasm is occupied with membrane-bounded granules of electron dense. Three types of pigment cells could be distinguished with electron density of cytoplasmic inclusions. Nerve myelins were observed near the pigment cells.
