The species was first described in 1996 [3] . The holotype is an adult male 71.9 cm long, precaudal length is 55.1 cm, caught in the Persian Gulf off the coast of Bahrain . immature male 59.8 cm long, precaudal 45.3 cm long, caught off the coast of India ; adult male 68.5 cm long, precaudal 52.7 cm long, caught in 1995 in the Persian Gulf off the coast of Kuwait ; adult male 75 cm long, precaudal 57.7 cm long, caught in the Persian Gulf off the coast of Saudi Arabia ; immature male 61.5 cm long, precaudal length 47.1, found in 1940 at the fish market in Visahapatnam , India; immature female, caught off the coast of Kerala , India and immature male 59 cm long, precaudal 45.4 cm long, caught in the Arabian Sea at a depth of 88β94 m in 1965 [4] .
Randall in his book βSharks of Arabiaβ in 1986 described this shark he saw in the Persian Gulf as Hypogaleus hyugaensi [5] , however, it later turned out to belong to the genus of striped sharks, and in 1996 the species was described by naming his Paragaleus randalli [6] .
Paragaleus randalli live in the northern Indian Ocean, in the Persian and Oman gulfs , off the west and south coasts of India ( Kach Bay , Gujarat , Kollam , Kerala , Kanyakumari , Tamil Nadu ), Sri Lanka and the north-east coast of India (Visahapatnam, Andhra Pradesh ) [7] . They are found on the continental shelf to a depth of 18 m [8] .
These sharks breed by placental live birth [9] . The length of the newborn is about 29 cm. In the litter there are up to 2 newborns. The maximum fixed size is 48.3 cm [8] .
The view is not dangerous to humans. These sharks are caught by trawls and gillnets. The meat is eaten, fish meal is produced from waste [10] . To double the population requires at least 14 years [1] . The slow life cycle makes sharks of this species vulnerable to overfishing and other anthropogenic impact. The International Union for Conservation of Nature has assigned this species the status of βClose to Vulnerabilityβ [2] .
