African Dwarf Crocodiles are timid nocturnal animals and solitary hunters. They predate mainly on small animals in rivers or nearby to the riverbank. They are also known as the Broad-Snouted Crocodile or the Bony Crocodile are the smallest extant species of crocodile in the world and are typically around 1.5 metres in length. They face persecution by humans and other animals and spend most of their daylight hours resting in burrows they make along riverbanks. They are vulnerable from #timber #palmoil #soy #meat #deforestation and hunting. Help them survive and be #vegan, #Boycottpalmoil #Boycott4Wildlife

Appearance & Behaviour
During they day they rest in burrows which they dig along the riverbank. These burrows have entrance and exit tunnels a few metres long. The crocodiles live among immersed tree roots, hanging into the water.
As they are cold-blooded reptiles, they moderate their body temperature by sun bathing and swimming in river water.
They propel themselves in the water using their vertically flattened tails. When on land, the animals get around by strutting along the ground.







Threats
African Dwarf Crocodiles are exposed to alteration and loss of habitat due to forest clearance for the timber industry as well as invasion of agricultural plantations such as palm oil.

African Dwarf Crocodiles face multiple threats which include:
- Habitat encroachment: Human settlements enroaching on their range.
- Agriculture: Habitat clearance for timber, palm oil and the grazing of livestock.
- Human persecution: Farmers actively hunt them as they fear that the crocodiles will kill their livestock.
- Illegal bushmeat trade: Hunting for bushmeat is also a threat.


Habitat
The African Dwarf Crocodile’s range stretches from sub-Saharan regions to west-central Africa, from southern Senegal to the Democratic Republic of the Congo, reaching as south as northern Angola.
Their primary habitat rainforest swamps and riverine, riparian regions of forests with dense vegetation and slow flowing currents. In addition, the Dwarf crocodiles are sometimes found in savannah pools.
Diet
To hunt, African Dwarf Crocodiles submerge themselves in the river with only their eyes and nostrils visible above the water line. Then they attack by sudden ambush and surprise once prey appears.
They are carnivorous and typically hunting birds, frogs, toad, rats, fish, crustaceans and other small animals. When food sources are scarce, the African Dwarf Crocodile can occasionally consume carrion. They can go for long periods without eating and often rest in their burrows throughout the dry season.

Mating and breeding
Females and males only interact during the breeding season and females build nests at the start of the wet season in May-June. Their nests are made from wet, decaying vegetation near the water’s edge, which incubates the eggs using the heat generated from the decomposition of plant matter.
There are typically 10-20 hatchlings which emerge after 85 to 105 days of incubation time. The mother will guard her nest (during incubation) and her offspring (after hatching) for an indeterminate period of time, as babies can fall prey to birds, fish, mammals or other crocodiles.
When hatching out of eggs, babies sing out with loud calls, which signal to their mother to unearth the eggs. She helps them come out and carefully carries them to the water in her throat pouch.
It was once mistakenly believed that these crocodiles cannibalise their young. Mothers will carefully carry their newly hatched offspring in their throat poaches into the water to safety where she guards them against predators.
