Lily：我很好奇青蛙的舌头是如何伸展得那么远的。我一直对动物的身体构造和它们如何适应环境感到着迷。青蛙的舌头似乎违反了我们对舌头应该如何工作的认知，所以我很想知道其中的科学原理。 Kisa Nishikawa：作为一名研究青蛙的教授，我研究了超过120种青蛙，发现青蛙舌头伸展的距离确实令人印象深刻。从我的研究来看，青蛙能够利用其舌头在一定距离外捕捉昆虫，这使得它们在捕食时不需要跳跃，从而减少了被捕食者发现的风险。此外，青蛙的舌头由非常柔软的生物材料构成，其舌头上的唾液在捕食时会发生液态和固态的转变，有助于它们有效地捕捉猎物。我发现青蛙舌头的长度大约是它们身体的三分之一到一半。虽然青蛙的舌头很长，但变色龙的舌头更长，可以达到身体的两倍。
