Nile Crocodile & Crocodile bird

Nile Crocodile

Crocodile bird

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.

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.

Why I Chose These AnimalsI 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.

How They Depend on Each OtherThe 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.

ConversationCrocodile: 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…

Here is a link that leads to a comic strip I made. It’s very short but a nice story. It’s about a crocodile moving to a new home and how he's trying to get used to the climate.

Hope you enjoy!

FUN FACTSDid you know that the crocodile bird’s family name is

Glareolidae.

The Nile crocodile can eat up to half its body weight at a time!

The crocodile bird has 175 different muscles in its body.

Nile crocodiles can run 12 to 14 km/h on land and are able to swim about 30 to 35 km/h.

Crocodile birds have orange eggs.

ANIMALDesert plover (An organism I created)

This animal lives in the desert and is able to make its own food like a plant.

It gets its energy from the sun; it converts the energy into sugar and water, and feeds its baby birds from its belly, which contains water and sugar. This makes the desert plover well suited for the desert heat.

During the evening, the desert plover has cozy fur that shields it from the frosty night temperatures common in the desert.
