Mainly this is a concept for a mix of interesting animals that could use a DLC with some minor additions to the swimming part such as special animations.
Animals
North American Beaver
Asian Small Clawed Otter
Capybara
African Penguin
European Pond Terrapin (Exhibit)
Pig-Nosed Turtle (Exhibit)
All of the animals in it are ones that are waterline dwellers that have both in and out of water behaviors to allow interesting options. They also spread out between continents with 1 each, it also lets the exhibit animals share a lot of work between them. It also opens the door for reskins (and resizes) for most of them with more turtles, otters, penguins, and even the Eurasian Beaver if they want. There are also some enrichment items like beaver dams as potential things for use tied into them.
Paths
Adding in alternate support options for paths and vehicles, wooden trestles for the train and such...along with similar ones for the others. Adding alternate vehicles to some...mainly an airboat and longboat option for boat tours (All boats in a tour would be the same type). There would also be a "Dock" path type that has the appearance of crossing supports and such. Also the "floating" pathways, and glass path.
Themes
Bayou: This one is more of the everglades and bayou with the appearance of being more worn down wood structures. Think of the swamp structures that have been there for a while.
Floating Village: More of the east asian stilt and floating villages
Decor
One major idea would be to add timed water jets and similar, being able to tie it into music or other things. A more algae tinted water option. Various boats and boat parts (Ties into the floating village theme, allowing things like pontoon boat bridges or floating eating areas (I'd love the parts for making a stationary riverboat to have a restaurant in)
Nature
Duckweed: patches to put on the top of water, shouldn't prevent animals from moving through it. Driftwood of different types that are more wet in appearance to be added to exhibits. More mangrove options.
Other
Adding a Fish & Chips shop along with a photo booth (Along with a modification that can be added to vehicles with camera points and a vendor station at the exit to the ride for it that would be at stations)
