Century Dictionary and Cyclopedia
nglobefishA gymnodont plectognath fish of either of the families Tetrodontidæ and Diodontidæ. These fishes are so named from their capacity for inflating themselves by swallowing air, the whole body or much of it becoming blown up like a balloon. In some cases, as that of Diodon, the fish assumes an almost perfectly globular form. See Diodon. Also called swell-fish, swell-toad, egg-fish, bottle-fish, bellows-fish, blower, etc.
Here also is the curious globefish, with its balloon-like body and prickly hide.
