The second national park I visited in U.S., Everglades. It is well known for being the habitats for numerous precious species. During our visit, we saw various kinds of birds, fish and plants. But the two highlights of this trip: For the first time, I saw so many crocodile at the same time. Apparently, there are many subspecies of crocodile, and south Florida, including Everglades, is the only place in the world where American crocodile and alligator coexist. We even heard the sound of crocodile (kind of scary)! And, when we took a boat tour inside the park, we saw a fisherman caught a shark! Wow!
