1. Nile Crocodile & Crocodile bird by: Nathan Everett 6B Nile Crocodile Crocodile bird

2. Symbiotic Relationship A symbiotic relationship is when two organisms ,like a crocodile and a bird, work together . They will both help each other in a unique way and look after each other.

3. The Story Behind my Backgrounds All my backgrounds are related to rivers, and my topic is partly about rivers . The first one shows water, representing a river. The second background shows papyrus. Papyrus comes from Egypt, and the Nile river is in Egypt. The last one has fish on it as a decoration and also because fish live in the rivers and the sea.

4. Why I Chose These Animals I chose these two animals because it was very interesting that a crocodile would get along with a small creature like a bird. I also learned in many books about these symbiotic relationships between different types of animals. I found many websites that helped me with this particular subject. The Nile crocodile and the crocodile bird had the most interesting symbiotic relationship I could think of.

5. How They Depend on Each Other The Nile crocodile and the crocodile bird depend on each other in a way that is very different from other animals. The Nile crocodile considers it helpful if the crocodile bird takes the bits of tiny gross things from its teeth, because the food rots and causes the crocodile to have pain. In a way, the crocodile bird (Egyptian plover) is the Nile crocodile’s dental floss. When a crocodile feels the need for a good tooth cleaning, the crocodile bird comes in very handy. The crocodile bird gets a free meal in return. There are no other birds that can actually survive after entering the mouth of a crocodile.

6. Conversation Crocodile: Come over here quick! I need you to clean my teeth! Crocodile: You’re awesome! Without you, life would be a waste. Bird: I know. I rock! I do everything for everyone. Crocodile: But I do stuff too, such as letting you eat food in my mouth! I could chomp you up if I wanted to, weak little birdy. Bird: I guess we’re both good. I mean without you, I have no food ; without me your teeth would not be cleaned, so you’re OKAY…
