My son is in 2nd grade and they are studying ocean animals. He has to gather information on octopus'. If we could get this information or told where to look online it would be helpful. 1. What does octopus eat? 2.Does octopus have any predators? 3.In what part of the ocean could we find octopus'? 4. Interesting facts that make your animal unique. He also has to make a 3D model so if anybody has any ideas that would be great.
