Where to find me in the Zoo Reptile and Amphibian House
Note: Description below should include Longevity, Behavior, and Reproduction information
Coloration is usually black or dark brown with yellow and black coloration on the belly. They are heavily “armored,” having bony plates in the neck, back, and tail scales. 


Behavior

In the wild the dwarf crocodile is both solitary and nocturnal. At night they will hunt for fish, amphibians, crustaceans, and other terrestrial prey close to the water or on land. During the day they will retreat to self constructed burrows or hide amongst tree roots.
 

Reproduction

After breeding, the female will construct a nest of vegetation in which to lay her eggs. Once the eggs are laid (usually 10-20) she will guard the nest from predators. After about 100 days the eggs will begin to hatch. The female will also protect the hatchlings as they make their way from the nest to the water.
 
The Zoo has one male and one female West African dwarf crocodile. The male hatched on December 13, 1979 at Woodland Park Zoo in Seattle, WA. He arrived on July 9, 2002. It is estimated the female hatched in 1974 at an unknown location. She arrived on July 9, 2002 from Los Angeles Zoo.
