我家养了一只小河蟹。它身体扁圆,一对黑芝麻大小的眼睛往上翘着,总是疑惑地看我几眼。如果你用手触摸它的眼晴,它的眼睛会立刻缩回眼眶,用大钳子在眼睛上方挥舞一番后,眼睛又突出眼眶。在小河蟹的身体两旁有八条又细又长的腿,腿上有细细的绒毛。它还有两只“力大无穷”的蟹钳,蟹钳总是紧贴着嘴,这样便于进食。 My family has a small crab. It is oblate body, a pair of black sesame size eyes upturned, always puzzled to see me glances. If you touch it by your hand, its eyes immediately retract into the eyes, and with the big pliers waving over the eyes, the eyes are still prominent. There are eight thin, long legs on both sides of the crab's body, and fine fuzz on the legs. It also has two “great” crab pincers, crab pincers always close to the mouth, so easy to eat.
