Great white sharks often reject people. Chum is whale oil and meat that fisherman use to attract sharks. I learned some things about chum. Chum is a mixture of things sharks like to eat. Chum is a mixture of whale oil, a little whale meat, and lots of fish meat and blood.
Most fishermen use chum to catch sharks.
I learned lots about shark teeth. There are different kinds of shark teeth like ancient teeth from 380 million years ago. I learned lots about cartilage. Cartilage is in the shark's body. We have cartilage in our ear and nose.
