目标物种的发育阶段表对于研究任何动物的发育都是有用的。虽然已经建立了几个有鳞目动物的发育阶段表，但没有出版壁虎科蜥蜴。我们已经建立了一个表的发展阶段的马达加斯加地面壁虎Paroedura pictus。该表包括从产卵到孵化的27个胚胎阶段，基于年表和外部形态。从产卵到孵化的间隔期为60天。产卵时体节11 ~ 16个，每天形成5 ~ 6个。产卵后第3天可识别出肢芽鞘。孵育2周后，通过腕骨/跗骨软骨形成检测推定的自足动物。产卵后3周，可见所有手指的软骨。孵化4周后可见皮肤色素，产卵40天后皮肤颜色图案明显。发展动力学238：100-109，2009年。(C)2008 Wiley-Liss，Inc.
A table of developmental stages of the target species is useful for studying the development of any animal. Although tables of developmental stages have been established for several squamates, none has been published for gekkonid lizards. We have established a table of developmental stages for the Madagascar ground gecko Paroedura pictus. The table includes 27 embryonic stages from oviposition to hatching based on chronology and external morphology. The interval from oviposition to hatching is 60 days. Eleven to sixteen somites were observed at oviposition, and 5 to 6 somites were formed each day. Limb bud swellings were recognized by the third day after oviposition. After 2 weeks of incubation, the presumptive autopod was detected by carpal/tarsal cartilage formation. Cartilages in all digits were seen by 3 weeks after oviposition. Skin pigment was visible after 4 weeks incubation, and the skin color pattern was apparent 40 days after oviposition. Developmental Dynamics 238:100-109, 2009. (C) 2008 Wiley-Liss, Inc.
