The guitarfish is known for an elongated body with a flattened head and trunk and small raylike wings. They are mainly found in tropical and temperate waters, traveling in large schools. Most adult guitarfishes reach five or six feet in length, though the Indo-Pacific Rhynchobatus djiddensis can weigh 225 kilogrammes (500 pounds) and grow to 3 metres (ten feet) in length. These fish are bottom feeders, preferring small crustaceans. Their teeth are small and numerous, usually arranged in 65 or 70 rows. Guitarfishes are ovoviviparous, with the young hatching out of the eggs before leaving the mother's body
