According to Gill and Punetha (1977), the mountain river Pseudoecheneis salcatus has 1-2 stannius corpuscles located 10 mm away from the excretory genitalia. [1] Phylogenetic relationships within this genus are poorly understood, though it has been suggested that there are two major lineages.[2]. Meso-adenohypophysis decreases in size at different times of the year. it shows black color in silver pigment while A2 cells are silver negative. homos- alike). They are ectothermic (cold blooded). Body divisible into head, trunk and tail. From the current study, it has been concluded that the growth, haematology and biochemical parameters are important indicators of ecotoxicology particularly contamination of the cadmium and health of the fish. World Wide Web electronic publication. Thyroid hormone (TSH) is present on the surface of meso-adenohypophysis and in some species of such as Poecilia, gonadotropes are found in the ventral side of meso-adenohypophysis.

It is made up of solid and polygonal cell clusters covered by cell cords and capillaries. It is interesting to note that in the early development of the embryo, the eyes of these fishes are laterally situated but being a bottom dweller they are shifted towards one side, as an adaptation to water pressure. The word Endocrine consists of two Greek words Gr., Endo = within, inside and Gr., Crinos = secretion, emission. He recognised it as surviving member of Crossopterygii (subclass of class Osteichthyes) and named it Latimeria chalumnii after the discoverer and locality. The number of acidophils is high during the rest of the year. ).Its secretion is called non-hormonal chemicals (such as sweat, milk, sebum, enzymes, etc. These two tissues are so closely related that they are considered together as neuro intermediate lobes. The male bears a brood pouch in which the female lays eggs and the latter remain there till they hatch. [3], In the wild it is found in Indian Subcontinent countries such as, India, Bangladesh, Pakistan, Sri Lanka, Nepal, and Myanmar. In some teleosts, the presence of thyroid follicles in various abnormal locations such as the main kidney, brain, esophagus and pleura has been reported. Studies have shown that the release of stannius particles affects the kidneys, alters kidney function, and maintains electrolyte homeostasis. These follicles vary in size and shape and are joined by connective tissue. Second dorsal fin is much smaller adipose. Federal Agency for Nature Conservation, Bonn, Germany.
