Carcharhinus sorrah ( Müller & Henle, 1839 ) is a kind of shark of the Carcharhinus genre and the Carcharhinidae family.
They live in the Indian and the western Pacific Ocean. From the Red Sea and Eastern Africa in particular at Madagascar, Mauritius and the Seychelles to the Philippines, China, Australia. They were also found at Vanikoro and the Solomon Islands. In a rarer way they are observed at the Gulf of Aden, the Gulf of Oman and the Sri Lanka. [first]
They live in waters between the surface and the 140 meters deep, often at coral reefs [2] .
The record of size for this species is 160 cm [3] , while the body mass is 28 kg [4] . The maximum age never found is 8 years [4] . The body is slender and elongated, the rounded muzzle, large and circular eyes, tight teeth and with oblique cuspids. The second dorsal fin is very small in size. The interdival ridge is present [5] . The tips of the pectoral fins, back and the lower lobe of the caudal are dark. The first ridge has a thin but visibly dark tip, while the pelvic fins and the upper lobe of the caudal are monotind [6] . The body in a general sense is gray or brown on the back, white on the belly with a golden area between the gangshakes and eyes [first] . A dark band extends over the sides starting from the pelvic fins towards the tail [first] .
Normally they frequent coastal waters [7] even if sometimes they are also located off [2] . They also tend to move near the bottom during the day and to go back to the surface at night [4] . Often during their life they do not move for more than 50 km, but it happens that emigrated for a total of 1000 [4] . Even if they prefer Teleosto fish, they occasionally feed on cephalopods and crustaceans [8]
The species is vivipara [9]
It is captured with a certain regularity through all its area especially by fishing pecuses of reduced scale [7] . Its meat is used for human nutrition and fins feed on the famous Asian trade. Vitamins and bowels as bait for other fish are extracted from the liver oil [first] .
