It seemed fitting that the 30,000 observation was a sea slug! Thanks @imogenisunderwater.

Before the project kicked off the top suggestions for most of the Sea Slug images I uploaded were either flowers or butterflies! The reason for this, the "machine" did not have enough images to "learn" what it was looking at. Oh boy has that changed. The "machine" is not perfect but now many of the sea slug images are correctly identified (not just Ceratasoma and Tambja). Sea slugs are not the only critters that the "machine" is learning more about thanks to your images. Fish, crabs, sea stars, urchins and many snails are now being more accurately identified because of all the amazing images you contributed.

I just wanted to thank everyone who uploads, identifies and comments on images in this project. I have seen so many amazing images and learnt so much from you.

Looking forward to the next 30,000 images!
