After spending some time playing with this website (which Wensi presented), I thought that it might make a really interesting platform for my project.
http://angiogenesis.amgen.com/

I like the navigation and think it might be cool to have the "panels" as different environments (maybe different parts of a jungle and moving into ocean)....these different environments can highlight the different types of arthropods.
I was also thinking of having some kind of timeline...maybe Cambrian Period and present time, to highlight the differences of arthropods then and now and to contrast the environments. Therefore, you could move around in many ways. Back and forth between different environments and back and forth in time.....I'm not sure how much this is making sense...it's hard to describe in writing...

From the various environments, there would be whatever links are necessary (animations, games etc...). Perhaps the user could build their own arthropod and place it in the environment....

Anyhow...some random thoughts.

Also, this video is hilarious (in a really terrible way)
