Sägerochen can be distinguished easily from the similar saw-sharks at the typical characteristic for all smelled - jederseits five at the body-underside of lain gill-openings -. Otherwise, the "saw-fish" see rochenartig flatly not at all but, with slim, three-edged front-body and thick rear-body, almost shark-nicely from. its most conspicuous characteristic is it long moved out, flat upper jaws, that are equally busy at both sides with a series of big, blunt teeth. Saw-fish usually don't become longer than 7 m. The biggest known become copy measured 10,7 m and had a weight of 2268 kg. One third until one fifth of the total-length is allotted to the "saw." As ground-inhabitants, smelled nourish these from small fishings and low animals for itself. On the food-search, they poke with its upper jaw the seafloor on.

Spread, reproduction Sägerochen live in offshore waters of the tropics and subtropics, they rise also in rivers (approximately in the Amazon). The ordinary saw-fish (Pristis pristis) of the East-Atlantic is found in the Mediterranean occasionally. Sägerochen bring to the world, that slipped (ovovivipar) already in the womb from the egg-capsules, approximately 20 kids. The already developed "saws" still are soft before the birth, the teeth cloaks.

Tools and weapon The upper jaw-fort-sentence, the so-called rust-rum, is used not only for poking in the ground with the food-search; this smelled swims, as to with a sword with it, and herschwingend - in fish-swarms in. On the way back, it consumes the injured and killed fish in silence. If it finds filled fisher-nets, it tears it in short time in order to get the loot. Although Sägerochen are not aggressive, they can become the human being extraordinarily dangerously with threat.
