| Summary: | igin, these anastomoses coil extensively over 200--300 m, before re-anastomosing with neighbouring vessels to form progressively larger secondary arteries (Olson, 1996). In the skipjack tuna Katsuwonis pelamis and the Atlantic cod Gadus morhua, the SCS forms capillary beds (Dewar et al., 1994; Burne, 1929), which are assumed to be typical of water breathing teleosts (Vogel, 1985a), before draining into the primary venous system. However, in Salaria pavo (prev. Blennius) and Zosterisessor ophiocephalus, it fails to do so (Lahnsteiner et al., 1990). The distribution and volume of the SCS has been widely discussed. To date it has been shown that secondary vessels supply secondary capillary beds in the body surface, the fins, the buccal cavity, the pharynx and the peritoneum, and it may 591 The Journal of Experimental Biology 206, 591-599 2003 The Company of Biologists Ltd doi:10.1242/jeb.00113 The volume of the primary (PCS) and secondary (SCS) circulatory system in the Atlantic cod |
