However, unlike the pronephros of amphibians, which have an external glomus and tubules with nephrostomes open to the coelom, the mature teleost pronephros has no connection to the body cavity and instead functions as a closed system (reference 1); This variation in nephron types [with external glomeruli that open into the coelom and with internal glomeruli that do not connect with the coelom] and their pattern of distribution suggest an evolutionary sequence. Ancestral craniates probably had an external glomerulus and nephrostomes, as do the first few to develop in very primitive craniates. (...) The mechanism would become more efficient as the coelomic recess into which each glomerulus discharged became a part of the tubule, that is, grew around the glomerulus as a renal capsule. The glomerulus becomes internal. The nephrostomes were lost during subsequent evolution, leaving the type of renal tubule found in most vertebrates (reference 2).[well established][VHOG]" @default.
