两种穿山甲外形量衡度的测定及比较

There are 7 species of pangolin in the world. This paper deah with the measurement of some morphology indices in Manis petadactyla and Mania javanica. Measured variables included the body weight, the total body length, the length of head and body, the length of tail,the length of protruding rim of external ear, the length of hind feet, the length of middle claws of fore feet, the length of middle claws of hind feet, the number of rows of scales round mid-body, the number of single flank scales of edge tail. All variables measured were compared respectively between this 2 species. The results indicated that: ( 1 ) there were no signifieant differences in body weight and length of hind feet between this 2 species, but differences in the other variables were extremely significant. (21 The ratio of the length of middle claws of hind feet and fore feet in Mania pentadactyla was less than 1/2 ( n = 48 ), while Mania jaw, nica was more than 1/2 ( n = 15 ) ; the length of protruding rim of external ear in Mania pentadactyla was over 10 mm { n = 38 ), whereas Manis javanica was under 10 mm { n = 13 ) ; the number of single flank scales of edge tail in Mania pentadactyla was not beyond 21 (n = 65), and Mania javanica exeeeded 21 (n = 14) . So the ratio of the length of middle claws of hind feet and fore feet, the length of protruding rim of external ear, arid the ntunber of single flank scales of edge tail should be regard as distinctive features and taxonomic indices between this 2 species. (3) The relationships between body weight ( Y) and the total body length, the length of head and body, the length of tail {X) were positive correlation, and satisfied relation equation Y= aX^b.

Physical Measurement and Comparison for Two Species of Pangolin

There are 7 species of pangolin in the world. This paper dealt with the measurement of some morphology indices in Manis petadactyla and Manis javanica.

So the ratio of the length of middle claws of hind feet and fore feet, the length of protruding rim of external ear, and the number of single flank scales of edge tail should be regard as distinctive features and taxonomic indices between this 2 species. (3) The relationships between body weight (Y) and the total body length, the length of head and body, the length of tail (X) were positive correlation, and satisfied relation equation Y=aX~b.
