Read the paragraph below. Above all, a mangrove forest is alive. When the tides come in, water laps at the trunks of the trees. As the tides recede, sediment washes around the mangroves' roots. Mangrove seedlings drop off their parent tree into the water when they're mature and float until they root in the soil. Mangrove leaves flutter in the wind and drift to the forest floor. Termites burrow in the mangroves' bark and dead wood; ants crawl on roots and branches. Snakes, crabs, parrots, lizards, alligators, fish, sponges, mosquitoes, snails, oysters, lobsters, mudskippers, and even sharks live here, depending on where the forest is located. In Bangladesh, you may see a tiger.
