🐟Largetooth sawfish
Harmaasaharausku (Pristis pristis) on uhanalainen kalalaji. Se voi kasvaa viisi metriä pitkäksi ja painaa tonnin. Kalan iho on karheiden nyppylöiden peitossa ja muistuttaa hiekkapaperia. Nimensä se on saanut muiden saharauskujen tapaan sahamaisesta pitkästä kuonostaan, jonka sivuissa on 12–30 paria hampaita muistuttavia nystermiä. Harmaasaharauskua uhkaa sukupuutto muun muassa siksi, että se päätyy kalastuksen sivusaaliiksi.
