As an example, here are the tags for one of my favourite animals, Helice crassa.
I think these give a nice sense of what we know about this crab.
I'm storing the tags for future analysis. I think there are some interesting ideas to explore, such as clustering the tags into meaningful groups. I'm also interested in how much we can learn about an organism based on these keywords. Can we automatically infer something about the ecology of the organism?
There is also scope for adding some semantics. Some of these tags are taxon names, and some refer to geographic places. Some are concepts, which could be linked to the relevant page in Wikipedia (Faviki is an example of this approach). At present the tags aren't clickable (i.e., you can't query by tag), but that would be a useful feature. One could get taxa that were tagged with a given term, such as "estuarine". For now, it's a quick way to get a sense of what we know about a taxon.
