The Saltwater Crocodile is the largest living crocodile species in the world. These crocodiles can reach 23 feet and over 2,200 pounds! They received their name due to their resistance to saltwater. Most crocodiles only enter the saltwater in emergencies while the Saltwater Crocodile just lives there. They are capable of living over 70 years in the wild and longer in captivity.
Saltwater Crocodile Reproduction
The Saltwater Crocodile breeds during the wet season when the water levels are the highest. The females select a nesting site where she and a male eventually mates. The male is a dead beat dad and doesn’t provide any care for his offspring. He leaves the mom and tries to find more potential mates. The female crocodile shows a high amount of parental care.
The mother guards her nest of eggs, even splashing water on the eggs to help prevent them from drying up. The eggs take 3 months to hatch. The sex of the offspring depend on the incubation temperature. Temperatures below 86 ºF (30 ºC) result in females. Meanwhile, temperatures above 89 ºF (32 ºC) results in male offspring. Once the eggs hatch, the female digs out the babies and carries them to the water in her mouth. Then, she protects the babies until they are able to take care of themselves. What a mom!
The International Union for the Conservation of Nature (IUCN) Red List categorizes the Saltwater Crocodile as Least Concern for Extinction. They have a fairly large range but the destruction of potential nesting sites is a concern. Another threat is hunting of the crocs for their pelts and meat. These threats are rather low though.
