[1] Phylogenetic relationships within this genus are poorly understood, though it has been suggested that there are two major lineages.[2]. PMC The presence of two distinct cells in meta-adenohypophysis suggests that the region secretes two types of hormones. The endocrine glands of mammals are more advanced and well-known, but the endocrinology of fish is limited to the effects of hormones on chromatophores, the function of sex cells, the activity of the pituitary and thyroid glands, and the control of osmosis. What is a trophic hormone? The sexual maturation of fish and the development of gametes take place in the presence of sex hormones. The Animal Diversity Web is an educational resource written largely by and for college students. 205 ). Color is brownish-gray on back, silvery on flanks and belly. Few populations are occur in Thailand, but only in the Salween basin. Parathyroid hormone secreted from the anterior and posterior pituitary glands, insulin and glucagon are secreted from the pancreas, calcitonin is secreted from the ultimobronchial gland, relaxin hormones are secreted by the ovarian and hormones of other glands. Beta (B) cells in the cells are involved in the secretion of insulin and in aldehyde fuschin (AF) pigment, it shows a dark purple. Elongated body is without scales.
