Key Questions
-
Which specialization was your favourite? Why?
-
What may be a disadvantage to a certain specialization (when their habitat is threatened or prey disappear can they move to/survive in a new place)?
What To Do
Preparation
- Hook up the computer to the computer speakers and to the LCD projector. Lower the screen on which the videos will be projected, if using a screen.
- Test to ensure Internet connectivity.
- Test to ensure that there are no broken links in the list below.
Demonstration
- Introduce the animal and its special feature.
- Click on the link in this document to access the feature.
- Show the class the video of the animal’s feature in action. Ask the students to write the name of the animal, the special feature they see, and a description of how that animal uses that special feature.
Owls
Many owls have unequal or asymmetrical ears (i.e. the left ear hole is higher than right ear hole). This gives owls the ability to hunt in complete darkness as they are able to pinpoint exactly where their prey is.

Hagfish
Hagfish can secrete a substance that reacts with salt water to form thick, gel-like mucus. This mucus is so thick that it suffocates the hagfish’s predator. To escape from its own mucus trap, the hagfish ties itself in a knot and removes all the mucus by sliding the knot down the length of its entire body!
