It is gizzard. -Alangator
they are both insects
A gizzard is a sack like organ at the back of the earthworms throat. The gizzard basically chews the earthworm's food since the worm doesn't have any teeth. The crop is a thinner organ closer to the head. The crop stores food.
The gizzard must be tough, for the gizzard's main function is to grind and digest tough food.
The gizzard is the structure that grinds up the food.
Reproduction
As earthworms move, they take soil into their mouths. Earthworms get the energy they need to live from organic matter found in the soil. From the mouth the soil moves to the crop, where it is stored. Behind the crop is a muscular structure called the gizzard. Here, the soil and food are ground. In the intestine, the food is broken down and absorbed by the blood. Undigested soil and wastes leave the worm through the anus.
Well, since earthworms dont have teeth the have this sack behind the mouth that squezes tightly then contracts over and over. Basicly it chews the food for the worm. Birds do it to but they also hold the chewed food in the gizzard for the baby birds
