Emerald tree boa (English spelling)

Japanese: エメラルドボア（英語表記）Boa canina; emerald tree boa

Order Lacertilia, Family Pythonidae. A relatively small arboreal boa with a body length of about 2m. Its back is green and spotted. It has a pair of large fangs at the front end of its upper jaw, but they are not venomous and are used to firmly grasp prey. Its tail has a great ability to prehensile. It is nocturnal and feeds on small mammals, birds, and lizards. During the day, it straddles tree branches with its head at the center and remains motionless in a unique flat coil. It lives in the tropical forests of northern South America. Its morphology and ecology are very similar to those of the green python found in Australia and New Guinea, and it is considered an example of parallel evolution.

トカゲ目ニシキヘビ科。比較的小型の樹上性ボアで，体長 2mぐらい。背面は緑色で，斑点がある。上顎の前端に1対の大きい牙があるが，毒牙ではなく，獲物をしっかりつかまえるのに使われる。尾は物に巻きつく能力が大きい。夜行性で，小哺乳類，鳥，トカゲなどを食べる。昼間は，木の枝に頭を中心にしてまたがり，独特の平たいとぐろを巻いて静止している。南アメリカ北部の熱帯林にすむ。オーストラリアやニューギニアに分布するグリーンパイソンと形態や生態が大変似ており，平行進化の例にされる。
