Irish Name: Crogall Iar-Afracach
ICUN Status: Not Evaluated

West African crocodiles are reptiles with long scaly bodies, short limbs and long muscular tails that help them push through the water. Their eyes, ears and nostrils are located on the top of their head which as an apex predator (at the top of the food chain), help them greatly when hunting for prey.

Where do they live (Natural habitat)?

West African crocodiles are found in west and central Africa, where they live in lagoons and wetlands in forested regions. Occasionally, they live in isolated pools in drier desert habitats, where they survive the arid desert environment by staying in caves or burrows.

How long do they live?

West African crocodiles usually live for about 45 years.

What do they eat?

West African crocodiles are carnivores (meat-eaters). They eat fish, reptiles, birds and a range of mammals.

Group name

They are known as a bask when on land and a float while in water.

Closest related species / sister species

West African crocodiles are related to other species of African and New World crocodiles such as the Nile crocodile and the Cuban crocodile. It is often confused with the Nile crocodile and was once thought to be the same species.

Fun Facts!

Teeth

Crocodiles go through thousands of teeth in their lifetime. If they lose a tooth, it is replaced very quickly with a new one.

Sweat

Crocodiles do not have sweat glands. Instead, they release heat through their mouths, which is why they are often seen basking with their jaws open.

New Discovery

In 2014, DNA testing revealed that Dublin Zoo’s crocodiles were actually West African crocodiles, not Nile crocodiles! The surprise discovery came after their siblings at Zurich Zoo were tested, uncovering their true species.

Male or female

The sex of a crocodile is determined by the temperature the eggs are incubated at. Depending on the species, the eggs being kept at different temperatures will result in males or females being born. This is called temperature-dependent sex determination.

Conservation

Not Evaluated

Until the 2010s, the West African crocodile was regarded as being the same species as the Nile crocodile. Since being recognised as a separate species, there has not yet been a census for the West African crocodile, so its IUCN status is unknown.

Threats

The main threats to the West African crocodile are habitat loss and hunting by humans for the bushmeat trade and for their skin.

Until the 2010s, the West African crocodile was regarded as being the same species as the Nile crocodile. Since being recognised as a separate species, there has not yet been a census for the West African crocodile, so its conservation status is unknown. However, it faces conservation threats including habitat loss and hunting by humans for the bush meat trade and for its skin.

They are 1.5 – 2.5 m in length.

The taxonomy of the Nile crocodile has long been the subject of debate. In the early 2010s, new research proved that the Nile crocodile is in fact two very different species: a bigger, more aggressive crocodile and a smaller, tamer species, the West African crocodile. In fact the larger Nile crocodile is more closely related to Caribbean crocodiles than it is to the West African crocodile.
