The passages “Animal Roles and Relationships” and “Unusual Animal Friendships” have similar central ideas. They both explain unusual relationships between different species of animals and how the animals rely on each other. For example The hermit crab and the sea anemone relationship and Suryia orangutan and Roscoe the dog. The hermit crab gets protection while the sea anemone gets left overs from what the crabs eats. Also Roscoe helped Suriya get better after she was moved to the endangered wildlife refuge. Even though both passages are written by different authors they both share similar central ideas.
