THE SWIMBLADDER AS A HYDROSTATIC ORGAN 73 The gas-gland In parallel with their retia, the gas-glands of bathypelagic teleosts are relatively large compared with those of shallow-water species. Some attention has already been drawn to this (Marshall, 1950, 1954; Jones and Marshall, 1953). Here a closer comparison will be made between various epipelagic. Text-fig. 36. Swimbladders of some epipelagic and bathypelagic fishes, showing the relative developments of the retia mirabilia and gas-glands. Epipelagic species: (a, a') Cypsilitrus cyanopterus; (b, b', b") Danichthys rondektii; (c, c') Exocoetus volitans; (d, d') Petatichthys capensis; (e, e') Hyporhamphus sp. Bathypelagic species: (f) Vinciguerria attenuata; (g) Argyro- pelecus aculeatus; (h) Myctophum punctatum; (j) Chiasmodon niger; (k) Melamphaes megalops. Gas-gland dotted; retia, with striations along the major axes. In a', b', b", c', d' and e' part or the whole of the gas-secreting complex is shown enlarged.
