The Splash: Underwater Sanctuary Wiki has a "Splash Checklist" to help members of the community keep track of or show other players the progress he or she has with discovering, establishing, and thriving different species.
Currently the images are displayed as the thriving icons because it is the easiest stage to obtain since it is used in other places on the wiki.
Also, please note, that if the image of the species is not displayed it is because a file of that species's thriving icon is still needed on the wiki.
When first using the checklist copy and paste the code from the darker box located under "Checklist Code" to where you want your checklist to be stored. After pasting the checklist you can change the "0" to the stage number your species is on.
The key located at the bottom of the checklist identifies which stage number will display which icon.
If you do not want to have your "Splash Checklist" on your user profile page you can paste your checklist in a special space by going to your user page (click your avatar in the top-right corner of the screen) and typing "/Splash Checklist" after it. Once you get to that space you can create a page for your Splash Checklist.
For species added after you copy and paste the checklist you would need to add the new set to the code yourself or come back to this page and copy the newly added set from the code below.
Thank you for understanding, and hopefully you find this useful to both your game-play and community interaction.
