SPONGES
"It might seem kind of surprising, but
sponges are actually a primitive form of animal. Looking at
these specimens, you can see that the familiar bath sponges
are soft, but other kinds of sponges are quite hard. Sponges
earn their living by filtering small particles of food from
the sea water."
