Description The family Alopiidae (thresher sharks) is found
distributed worldwide in tropical and temperate
seas. Alopiidae have one genus and three species
viz., the pelagic thresher, Alopias pelagicus
Nakamura, 1935, the bigeye thresher, A.
superciliosus (Lowe, 1839) and the common
thresher, A. vulpinus (Bonnaterre, 1788). On 20th
June, 2013 a single specimen of A. pelagicus (Sex:
female; total length: 270 cm; weight: 3000 g) was
landed in by large meshed drift gillnet (“Paruvalai”)
operated from fishing craft (“Vallam”) in
Tharuvaikulam fish landing centre. The gear was
operated between 100 and 150 m depth, at a
distance of 60 nautical miles from the coast. The
specimen was photographed and morphometric
measurements were made with a measuring tape
to the nearest centimeter and weight was taken to
the nearest gram. The species identification was
carried out based on Compagno (1984).
