Developmental genes and calcium-sensing receptors in fish gills are similar to those within the parathyroid glands of birds and mammals. Due to increased circulating calcium, there may be other symptoms associated with hypercalcemiamost commonly dehydration. The superior pair are not dragged downwards by the fourth pouch to the same degree. Hyperparathyroidism is the state in which there is excess parathyroid hormone circulating.
