小编摘要:你能想象世界上最小的变色龙有多长吗?仅仅2.9CM!

导读:2.9CM长的 Brookesia micra,不仅是世界上最小的变色龙,而且也是最小的爬行动物之一。科学家解释说,这种生物的出现是由于岛屿矮态(island dwarfism)的影响,即在与世隔绝、资源有限的环境条件下,体形庞大的动物经过几代的进化会变小。


Match-tip tiny, Brookesia micra is the smallest of four new chameleon species found on the African island country of Madagascar. With an average adult length of just over an inch (2.9 centimeters) from snout to tail, B. micra is among the tiniest reptiles in the world.

Scientists think the diminutive new chameleon species might represent extreme cases of island dwarfism, whereby organisms shrink in size due to limited resources on islands.

"The extreme miniaturization of these dwarf reptiles might be accompanied by numerous specializations of the body plan, and this constitutes a promising field for future research," study leader Frank Glaw of Germany's Zoological State Collection said in a statement.
