Dwarf crocodile

Latin Name

Class
Reptiles

Order
Crocodylia

Description

Uniformly dark in color with brown eyes. Body is heavily armored from head to tail with bony, plated scales. They can reach a length of 5.5 feet and weigh 70 pounds.


 

Range

West Africa and west central Africa (Guinea, Ghana, Nigeria, Gabon, Cameroons, Liberia and Angola)


Status

The dwarf crocodile is listed as endangered. It is still exploited for its hide, eggs, meat and as a pet.


Habitat

Tropical forest zones, prefering slow-moving water while avoiding major waterways.


Niche

Aquatic and nocturnal, feeding on crabs, frogs, fish and, occasionally, small mammals that wander into the water or are captured by the riverbed.


Life History

Dwarf crocodiles lay about 20 eggs at a time in nest mounds made of vegetation. Incubation is 87–126 days, depending on atmospheric temperature. Timid by nature, dwarf crocodiles are slow moving and do not like to bask as other crocodiles do.


Special Adaptations
  • Eyes placed high on the head enable the crocodile to see above the water line while keeping its body submerged.
  • Special transparent membranes protect the animal's eyes during struggles with prey.


Bonus Content

Dwarf crocodiles have claws in front to help grab prey in the water, with the back feet webbed for a stronger swimming stroke.

Wings, Paws and Claws
