What is the difference between a fishes circulatory system and a mammals circulatory system?Thanks.?
I know about the single/double circulation, closed/open system and the heart chambers.
Does anyone know any other differences?
Thanks.

The circulatory system in fish has been fully described (Mott, 1957; Randall, 1970), and until recently it was thought that fish possess a lymphatic system like that of mammals (Kampmeier, 1969). In 1929, Burne observed the existence of a `fine-vessel’ system, which he did not believe constituted a part of the traditional circulatory system or to be of lymphatic origin, yet he could not demonstrate a connection to the vascular system (Burne, 1929). In 1981, Vogel and Claviez, using corrosion casts and scanning electron microscopy (SEM), rediscovered Burne’s fine vessel system and revealed their connection to the primary circulatory system (PCS) through interarterial anastomoses (Vogel and Claviez, 1981). Vogel and Claviez recognised these vessels as a separate system, termed the secondary circulatory system (SCS).
