Moreover, bullfrogs are part of many wetland food webs. Outside their native range, they can become invasive.

Fun Fact: A bullfrog’s deep, booming call can be heard from up to a kilometer away.

Cottonmouth

Scientific Name: Agkistrodon piscivorus

Class: Reptilia

Diet: Carnivore

The cottonmouth, or water moccasin, is a venomous snake that lives in swamps. It swims through the water in search of prey. It is well adapted to the wetland world.

Interestingly, the cottonmouth gets its name from the white lining of its mouth, which it shows as a warning. It is one of the few venomous snakes that hunts largely in water. It preys on fish, frogs, and other swamp animals.

Cottonmouths live in the swamps, marshes, and streams of the southeastern United States. As carnivores, they eat fish, amphibians, and small animals.

Moreover, cottonmouths help control fish and amphibian populations. They remain fairly common across their range.

Fun Fact: The cottonmouth flashes the white inside of its mouth as a warning to threats.

Great Egret

Scientific Name: Ardea alba

Class: Aves

Diet: Carnivore (fish, amphibians)

The great egret is an elegant wading bird commonly found in swamps. It stalks the shallow waters on long legs. Wetlands are its perfect hunting ground.

What sets the egret apart is its patient hunting style. It stands or wades slowly, then spears fish and frogs with a swift jab of its bill. Its long legs let it hunt in deeper water than many birds.

Great egrets live in swamps, marshes, and wetlands across much of the world. As carnivores, they hunt fish, amphibians, and small animals.

Moreover, egrets help balance swamp populations and indicate wetland health. Once hunted for their plumes, they have recovered strongly.

West Indian Manatee

Scientific Name: Trichechus manatus

Class: Mammalia

Diet: Herbivore (aquatic plants)

The West Indian manatee is a gentle giant that grazes in swamps and slow waterways. It drifts calmly through the wetlands. Swamps and rivers provide its plant-based diet.

Interestingly, the manatee spends its days grazing lazily on aquatic plants in warm, shallow waters. It moves slowly and peacefully, coming up to breathe every few minutes. It seeks out warm swamps and springs in colder months.

Manatees live in the coastal waters, rivers, and swamps of the southeastern United States and the Caribbean. As herbivores, they feed on seagrasses and aquatic plants.

Moreover, manatees help maintain healthy waterways by grazing on plant growth. Boat strikes and habitat loss have made them a conservation concern.

Fun Fact: A manatee can eat around a tenth of its body weight in plants each day.
