Dolphin
In the vast ocean live many creatures with great intellectual and physical capacities.Dolphin is one of those great creatures,whose capacities to think and move at an astounding rate puzzle those who study their behaviors,Dolphins possess something that makes them different from all the other sea creatures.It is not strength or speed but the size of their brains.Dolphin' s brain is almost the same size as that found in the human head.They live for a ling time.
Dolphins' babies are born in the water.They can grow up to three and a half meters long.
Dolopins use sound to help them find their way,look for their food and talk with each other.Sound is just like their eyes and mouths.
海豚
大海里住著許多智力發(fā)達(dá)、身體強(qiáng)健的動(dòng)物,海豚就是其中之一.它反應(yīng)靈敏、動(dòng)作迅速,讓那些研究它們行為的人們深感震驚.海豚擁有一些與其它海洋生物不同的地方,它的優(yōu)勢(shì)不在于它的力量和速度,而在于它的大腦.海豚的大腦與人腦大小一樣大.它們的壽命很長(zhǎng).
海豚在水里生育,它們能長(zhǎng)到三點(diǎn)五米長(zhǎng).
海豚利用聲音幫助自己認(rèn)路、覓食與彼此之間交談.聲音就像它們的眼睛和嘴一樣.{不是原創(chuàng)}
