There are a lot of species missing from your database. We can help fill them in, but it would be nice if when you add a species while editing a dive (only place you can as far as I know) that species gets added to the ones you've seen.

it's actually there already :)
Look right under the species picker on the dive editor in the species tab
let me know if you run into any trouble :)
