Short-lived Chameleon

Scientists have discovered a chameleon species that spends a good two-thirds of its life inside an egg: Furcifer labordi lives about 8-9 months as an embryo, and has a post-hatching lifespan of just 4-5 months. As far as the scientists know, this strange life history is unique among all land vertebrates, and may help researchers better understand how certain ecological and hormonal factors influence life history evolution.

The small F. labordi lives in the extremely arid southwest region of Madagascar. The desert-like, spiny-forest area experiences a long dry season from March through November, and a rainy season between December and February. This harsh, variable environment may be one of the reasons for the odd life history of F. labordi.

Rare white albino tadpoles

Rare albino tadpoles have been found in a garden pond in Wales.

The tadpoles have the distinctive pink eyes and off-white skin coloration associated with albinism. Although isolated single examples of albino frogs, toads and newts have been seen before this is the first time a whole group has been found.

The pond's owner, who first noticed the white-tinged tadpoles, said he did not see any albino frogs using the pond during the breeding season.
