Study Notes
Crocodile Habitat
- Crocodiles are found in Africa, Australia, Asia, Central America, and North America.
- Each species has unique needs, but all require a tropical environment with water (fresh or salty) and safe breeding grounds.
Environmental Requirements
- Tropical climate with warm temperatures all year round.
- Water availability, including salty or brackish water.
- Safe places to lay eggs, away from human disturbance and other predators.
Adaptations to Environment
- Ability to survive in brackish water due to a special gland that helps their bodies deal with salt levels.
- Can live in tropical climates with high humidity.
Habitat Location
- Jungles of Papua New Guinea and marshes near the Nile River are examples of suitable habitats.
- Brackish mangrove swamps along coastlines and in the Florida Everglades are preferred habitats for American crocodiles.
Threats to Crocodile Habitats
- Human activities such as deforestation and swamp drainage lead to habitat destruction and depletion of crocodile species.
- Crocodiles are pushed out of their natural habitats as humans expand cities and settlements.
