Ideas for a Presentation

So there is a good chance I have to do a presentation at my college on reptiles. Now I have done this for little kids before, but am at a loss for college age people as they are more knowledgeable then a little kid. Any ideas of what to talk about?

Firstly, what class is it for? What year are you and your classmates in currently? That may determine the type of content you'll want to focus on.

Secondly, you'd be surprised at the number of college graduates who are not much more knowledgeable than little kids on the subject of animals...

It is for a zoology II class and I have a few ideas (identification, how they are helpful, stuff like that). I am a sophomore, but there are people of all ages in the class.

Well that was more what I meant...like if it was a higher level class you might go into some greater detail. Since venomous snakes are always a fun topic that brings out a lot of opinions, you could highlight native species and ways to identify dangerous ones? Could also tackle some myths about red-on-yellow-... (shovelnose snakes are great example of why that rhyme doesn't always work), slit vs round pupils (green mamba), triangle shaped heads (watersnakes), etc.
