Abstract
THE majority of marine fishes, in regard to reproduction, readily range themselves into certain groups according to the condition of the eggs on deposition. Thus (a) a considerable number have delicate pelagic ova, which are generally separate, though in the frog-fish, for instance, they form gelatinous masses, (b) Others are characterised by the deposition of thick-walled ova, connected together in more or less firm masses, on or near the bottom, or in special nests, (c) A third group is distinguished by laying ova which have filamentous processes or adhesive surfaces for attachment to foreign structures; and some place them in brood-pouches of (he males, in which case, however, the capsules appear to be more delicate, (d) A fourth series have their large eggs enveloped in dense horny capsules, which either are fixed by their twisted filaments to marine bodies or find sufficient protection on the extensive sandy flats where they are deposited, (e) Finally, a few produce living young, this condition ranging from the well-marked ovo-viviparous Zoarces to the even more complex state in the sharks.
