informative speech

[gesswhosbak]

I am currently enrolled in a public speaking class, i would like to give an informative speech dealing with some aspect of saltwater fish. The time requiremtents are 3-5 minutes so i would need enough info on the topic to last that long. I was just wondering if anyone had some good topics i could consider that wont bore people who arent into saltwater. Oh and the speech is due thurs:notsure:

The dark side of the "Finding Nemo" craze, ie Clown + Hippo Tang in 10 - 20 gallon tanks.

Or the efforts to improve capture methods on reefs.
NPR recently did a multipart segment called "reefs in the balance." I only caught a brief portion of it but it was really good. You might be able to get some topic ideas from their transcripts, which I believe are available online.
