Something is shredded if it has been cut into small pieces. Usually the pieces are strips that are longer than they are wide. People shred vegetables to make salads, and they shred paper so that noone can read what was written on it.
The person who took the picture does not have a very good shredder, as some of his paper shreddings are very readable.

A shrimp, also called a prawn in many countries, is a sea creature that usually grows to a few inches long. They are a very popular food, and can be eaten boiled, fried, barbequed and many other ways, plain or with a sauce. They are quite often cooked whole and you have to remove the head, legs and other inedible parts yourself.
