The countries that Nile crocodiles are native to are: Angola; Benin; Botswana; Burkina Faso; Burundi; Cameroon; Central African Republic; Chad; Congo. Etc

The Nile crocodiles habitats Consists of a wide range of aquatic areas, like: lakes, rivers, swamps including both freshwater and mangrove. They sometimes are seen in coastal areas.

The size of the Nile crocodiles prey depends on the size of the crocodile. Young hatchlings feed on smaller prey including: small fish, frogs, insects, and small aquatic invertebrates. Juveniles eat wider prey including; birds, turtles, snakes, Nile monitors, mid-sized mammals and many other organisms. The adults are apex predators so they prey on multiple sizes of birds, reptiles and mammals including; gazelles, waterbucks, giraffes, Cape buffalo, young hippos and many other animals.

The smaller hatchlings are usually prey to bigger animals such as large birds (ostrich), large snakes (pythons) and other bigger animals.

the Nile crocodile species are also threatened by people hunting them.

The Nile crocodile is symbiotic with the Egyptian plover. The Egyptian plovers are birds that share the same habitat as the Nile crocodile, in which it flys near lakes, rivers and other bodies of water. You will also see the Egyptian plovers hopping around in crocodiles mouth's.

Factors that affect the Nile crocodiles Consists of the changing of temperature, humidity, precipitation, and time of day; this occurs monthly and daily.

Nile crocodiles are invasive in parts of South Florida, mainly in surrounding areas in the Everglades

Nile crocodiles have been introduced into the Everglades through illegal pet trade or pet captivity.

3 effects the Nile crocodile has had on Florida’s ecosystem is

1.) Nile crocodiles threaten native species of Florida through predation and competition

2.) They are dangerous to humans

3.) much bigger than Florida’s native large crocodilians, so they take up more food and space

1.) Education and awareness is important for controlling the Nile crocodiles.

understanding the Nile crocodile Is important because you know that they are harmful and to stay away.

Signs warning that the area has the crocodiles helps people stay away

Pros of this method is that people will be safe and have knowledge over the species, cons is that the Nile crocodiles won’t be able to attack humans since they see us as a source of food

2.) Capturing and removing the problematic Nile crocodiles

Capturing the problematic crocodiles that are more aggressive then others will help the area stay calm

Using traps or relocating the location of the crocodile will seperate the aggressive ones from the calm ones.

The pros of this method is that the area where the crocodiles are won’t be so problematic, cons is that the problematic crocodiles will still be alive and could act the same even if put in another location.

3.) Having protective laws that give the Nile crocodiles their space and protect their habitat

have protective laws that prohibit trade and illegal hunting to protect the population of the Nile crocodiles

The pros of this method is that their will be less conflict between humans and Nile crocodiles, cons is that hunters won’t be happy and will get in trouble if they hunt a Nile crocodile

Capturing problematic Nile Crocodiles and returning them to their place of origin will not only save the area they invade but also:

Lower the invasive population

Return them back to their homes where they belong

Fix the ecosystem which they have interrupted

Give them more resources which help them

Lower the domination/ abundance of resources in their homeland

BEST OPTION BECAUSE

does not harm them

takes them out of a place where they could be harmful

Does not require much convincing

MATERIAL NEEDED

Boats

Permission from government/state

(Since we are moving them across nation)

Consent will need to be granted because though we are moving them there might be cons the law has in mind
