First Report of Occurrence and Conservation Status of Black Softshell Turtle, Nilssonia nigricans (Anderson 1875) (Reptilia: Testudines: Trionychidae) in West Bengal, India

First Report of Occurrence and Conservation Status of Black Softshell Turtle, Nilssonia nigricans... The study reports the first record of the Black softshell turtle, Nilssonia nigricans (Anderson in Ann Mag Nat Hist 16:282–285, 1875), a species categorised as “Extinct in the Wild” category by IUCN (http://www.iucnredlist.org/, 2002) from a locality in West Bengal (Baneswar village, District Cooch Behar, West Bengal; 26° 23.912′ N, 089° 29.872′ E).

Abstract

The study reports the first record of the Black softshell turtle, Nilssonia nigricans (Anderson in Ann Mag Nat Hist 16:282–285, 1875), a species categorised as “Extinct in the Wild” category by IUCN (http://www.iucnredlist.org/, 2002) from a locality in West Bengal (Baneswar village, District Cooch Behar, West Bengal; 26° 23.912′ N, 089° 29.872′ E). The study conducted during January, 2017 to January, 2020 found the species to occur in a protected temple pond and several other ponds in the locality. The mean Straight Carapace Length (SCL) and the mean Straight Carapace Width (SCW) of adult turtles were 47.3 ± 10.11 and 37.66 ± 4.24 respectively, whereas the mean SCL and SCW of juveniles were 13.5 ± 6.36 and 12 ± 4.24 respectively. The species is omnivorous in feeding habit. It enjoys local community protection. Further conservation efforts are required to save this local population from future extinction due to urbanization pressure.
