What are common characteristics of the animals that live in swamps?

The most common characteristics of the animals that live in swamps include having webbed feet to help them move quickly through water environments as well as camouflage to protect themselves. Camouflage also helps them hide within their surroundings and hunt. Animals that live in swamps also can remain in the water for an extended time.

What do swamp animals eat?

Swamp animals typically eat insects, spiders, earthworms, as well as slugs. Swamp animals usually eat the animals that fall below them in the food chain and are native to the swamp habitats. Swamp Animals often eat small fish, insects, crustaceans, and mollusks. Herbivore swamp animals eat algae, water lilies, cattails, and algae.

How do wetlands help endangered species?

Wetlands help endangered species because they improve water quality and provide wildlife habitat. Wetlands are also important as they maintain ecosystem productivity, reduce coastal storm damage, and provide recreational opportunities. Wetlands are significant in the preservation of endangered species by improving water supply and providing possibilities for education.

How are freshwater animals adapted to their environment?

Freshwater animals adapt to their environment through gills that obtain oxygen and allow them to live in rivers and streams in which the water is cooler and has a higher oxygen level. Freshwater animals also need to swim fast to catch food and utilize their environment to create their home.

Why are freshwater animals going extinct?

Freshwater animals are going extinct due to the creation of man-made elements that block migration routes for fish and disrupt habitats. The water withdrawal for human use also shrinks and degrades habitats as well as the draining of wetlands for development depletes habitats. Other reasons include overexploitation, pollution, and global warming.
