| 説明 | It is able to hang upside down, twist its body, and peer into holes and under bark looking for reptiles and invertebrates such as insects and scorpions. It can even walk down a tree branch at a nearly vertical angle. It can do this because it has a 'double jointed' ankle which allows it to flex backward and even a bit sideways. It also has a behavioural adaptation, in that it can use its tail and wings, as well as its legs to brace itself in position as it seeks its prey. |
