Hello there!

So, to keep it fairly short and direct :

I LOVE that they added the man-o-war as a collectable "beetle" and it gave me an idea: why not add a new aquapedia section near the beetles?
The mechanics can work exactly like the beetle book does, but for aquatic life!

The African continent has an incredible amount of curious, colorful and fascinating sealife, and I think this could be a really neat addition! Especially considering the man-o-war is not a beetle

An aquapedia could also be a great way for people to learn about specific creatures and maybe even plants,if/ how / why they are endangered etc in their descriptions.
It could be a great way to raise awareness, plus, it's would just be a great addition to have colorful fascinating sealife!

Of course there can be event creatures like we currently have with the beetles and man-o-war, but we could also add these drops to the water encounters, like "clean the lake?" could occasionally drop a fish, snail, plant or whatnot to add to a collection like beetles!

For the "larvae" sprite, for any aquatic life it could be a little fish egg, and for maybe plants just a little sapling etc. Something rather simple to show the age stage

If love to hear your opinions
