Summary of clip: While searching for Nemo, Dori and Marlin (Nemo's father) find themselves in a dark abyss deep in the ocean. They are attracted to a light in the darkness that turns out to be a predator that wants to eat them.

Connection of flickclip to the concept: The predator that they run into is called an anglerfish. Anglerfish have adapted to their darkened environment in two ways.
1. With a spiny protrusion that hangs above their "head". This protrusion dangles and is bioluminescent so as to attract prey in the darkened environment
2. Their bodies are dark brown or grey so that they blend into the dark. They are even difficult to see under their own luminescence.
Suggestions to teachers:

1. Suggested questions for students when viewing the clip:

a. What other adaptations do predator fish use to attract prey?

b. What are some adaptations that other predator animals (not fish) have to attract prey?

c. What features allowed Dori and Marlin to escape?

d. Are prey adapted to escape from predators? How?

2. Have the students do research on predator/prey interactions and choose one adaptation (not talked about in class) to display, describe, perform, in a creative way for the class.

3. Have the students build Anglerfish headwear to wear at home or around school. See how many students/family members react and discuss how this is an example of an "attraction" adaptation. The students could keep journals regarding how people reacted, i.e. looked at me funny, asked me about it, avoided me, etc.
