Everglades Wetland, Florida, USA

Sponsored by

United States, Florida

“River of grass” – Everglades is one of the few habitats on Earth that includes the widest variety of animals and plants and it has many kind of endemic species, too. It’s the second biggest national park in the USA (Everglades National Park). Most of us think that Everglades is a big swamp, but it is not really. It’s a very slow moving river. It moves only 30 meters a day. The 160km long and 97km wide system begins with the Kissimmee River and ends in Florida Bay. Water leaves the lake in the wet season and forms a slow-moving river. Sadly there are many endangered species in the Everglades, like the American crocodile, Green turtles, andWest Indian manatee as well.

The Everglades is unique because freshwater meets saltwater from the Gulf of Mexico in the Florida Bay and they create a perfect ecosystem for both of fresh and saltwater creatures as well. The name “River of grass” came from the sawgrass prairie found across the region.

Comment by the expert

Fritz Rohde: I would have liked to seen additional fishes such as Least Killifish.

Lawrence Kent: The male pygmy sunfish look healthy and their behavior appears natural, because you’ve given them lots of room and a great biotope. I appreciate your recreation of the reeds/grass that dominates the Everglades, which I visited earlier this year.
