do, and are capable of a considerable degree of personal affection. There are

humble little shellfish known as the mussel (贻贝)。
Mussels are
found worldwide. Some live in the sea. Others inhabit freshwater streams and
lakes. When you try to move a mussel from a rock, you will discover what an
incredibly firm grip it has- a necessity if the mussel is to resist the sharp
grab of a hungry seabird or the pounding waves of the sea. How does it manage to
cling so tight When it choose a place to set up home, it pokes its
