Summary. – The crowned river turtle, Hardella thurjii (Family Geoemydidae), is a large (CL to 65 cm) freshwater turtle, largely confined to lentic waters in the Indian subcontinent. The species shows extreme sexual size dimorphism, females attaining a length over three times that of the males. Only plant matter is taken by the species in some areas, but elsewhere prawn or fish may be taken, possibly as carrion. Courtship and mating take place during the summer months in northern India, and 8–19 ellipsoidal eggs may be produced. Heavy exploitation for its flesh and extensive wetland development projects are among the factors suspected to have made the turtle rare in localities where it was once common, although there is some evidence that the species is difficult to observe in the wild. Distribution. – Bangladesh, India, Myanmar?, Nepal, Pakistan. Distributed across the northern Indian subcontinent from Pakistan to Bangladesh, and possibly in western Myanmar. Synonymy. – Emys thuryi Gray 1830 (nomen oblitum), Emys thurjii Gray 1831, Hardella thurjii, Hardella thurjii thurjii, Emys flavonigra Lesson 1831, Clemmys thurgii Fitzinger 1835 (ex errore), Emys thurgii, Batagur thurgii, Hardella thurgii, Kachuga oldhami Gray 1869, Hardella indi Gray 1870, Hardella thurjii indi, Batagur falconeri Lydekker 1885, Batagur cautleyi Lydekker 1885, Batagur floweri Lydekker 1885, Batagur watsonii Lydekker 1886, Geoemyda pilgrimi Prasad and Satsangi 1967. Subspecies. – No subspecies are currently recognized, as no genetic or consistent morphological differences can be found between the western population from the Indus basin (for which the name Hardella indi Gray 1870, was established) and those further east. Status. – IUCN 2008 Red List: Vulnerable (VU A1cd+2cd) (assessed 2000); CITES: Not Listed.
