Abstract

ABSTRACT
Sexual Dimorphism, Reproduction and Prey of Long Tailed Lizard Takydromus sexlineatus
Daudin, 1802 (Lacertilia :Lacertidae). The morphology and reproductive biology of Takydromus
sexlineatus were studied in Bogor. Males are larger than females. There is sexual dimorphism on
head size and tail length (larger and longer tail on males) of body size among sexually mature
adults, apparently as a consequence of sexual selection. The diet of T. sexlineatus consists of
variety of insects and their larvae, arachnids, decapods and snails. Most of the diet are insect
(more than 70 % for adults and juveniles). There are higher prey competitions at adult skinks
between males and females, adult females and juveniles, but not between adult males and
juveniles. The length of adult males and females are 44.6 - 58.1 mm and 49.6 - 62.3 mm respectively,
lay eggs throughout the year with 2 -3 clutches, per clutch consists of 1 - 3 eggs.
