The free screensaver, Puffer Fish, was created by RateMyScreensaver.com and contains 17 high resolution images of Puffer Fish. The Tetraodontidae is a family of primarily marine and estuarine fish. The family includes many familiar species which are variously called puffers, balloonfish, blowfish, bubblefish, globefish, swellfish, toadfish, and toadies. They are morphologically similar to the closely related porcupinefish, which have large conspicuous spines (unlike the small, almost sandpaper-like spines of Tetraodontidae). The scientific name, Tetraodontidae, refers to the four large teeth, fused into an upper and lower plate, which are used for crushing the shells of crustaceans and mollusks, their natural prey. - wikiScreensaver Picture Count: 17 Screensaver Type: Slideshow Credit: All images in this screensaver fall under one of the following licenses: Creative Commons, Attribution ShareAlike 2.0, public domain, GNU Free Documentation License.
