蝙biān[蝙蝠](biānfú)哺乳动物,头部和躯干像老鼠,四肢和尾部之间有皮质的膜,夜间在空中飞翔,吃蚊、蛾等昆虫。视力很弱,靠本身发出的超声波来引导飞行。{bat (Chiroptera); flying nocturnal mammal with a mouse-like body and modified forelimbs that serve as wings covered with a membranous skin that extends to the hind limbs, and feeding on insects such as mosquitoes and moths. Having poor sight (hence the expression, ‘blind as a bat’), the bat transmits ultrasonic waves to navigate its flight path.} |
