10 Things You May Not Know About the Northern Territory Saltwater Crocodile

When you holiday in the Northern Territory, it is wise to check with Parks and Wildlife centres to find out where it is safe to get into the Water. There are water leisure centres and tours to keep you safe from the saltwater croc. Visit a crocodile park or farm; they allow you to hold a baby croc. They are very soft and cold to the touch. Help feed the small and large crocodiles. Get some great photos. Read the following to find out what you may not know about the 'salty'.

1. A saltwater crocodile has 65 teeth.

Their teeth are sharp-pointed, inter-locking and are perpetually replaced. A single croc might grow up to 3,000 teeth in its lifetime. How amazing is that? A small bird hops right into the prehistoric estuarine Crocodile's mouth and cleans its teeth.

2. A saltwater crocodile swallows stones and pebbles

It is believed the purpose of this is to give them ballast when diving, and are often ingested to aid digestion - crushing food by a grinding action within the gizzard of the stomach. 'Kill two birds with one stone!'

3. A saltwater crocodile can and will walk hundreds of kilometres overland.

Because Northern Australia has some small, inoffensive crocodiles restricted to brackish or fresh water, most people think all inland crocodiles are freshwater crocodiles. That is very misleading. It can and has lulled people taking great risks in what are now unsafe places as they know the freshwater crocodile to be usually harmless,unless provoked. The saltwater crocodile starts its life in brackish or fresh water, and only travels out to the ocean when it is almost fully grown to search for new territory.

4. A saltwater crocodile can and will swim in from ocean estuaries hundreds of kilometres

They swim into freshwater tributaries, lagoons, swamps and rivers. Saltwater crocodiles have been known to live there for the rest of their lives. So, do not think that they are only in the ocean.

5. A saltwater crocodile has heavily ossified scales along its back referred to as the armour.

Their scales are the same substance that hooves and nails are made from; keratin. One of the main functions of crocodile scales is for their protection.

6. The saltwater breeding female crocodile will cool her eggs with water carried by her mouth to the nest or spray urine on them.

In the breeding season between September to May, the female builds a nest of a scratched up pile of rotting plant matter and mud or sand. She lays about 30 to 90 eggs and covers them with more of the same material. They are incubated for 3 months. The saltwater crocodile lays in the wet season and many nests are destroyed by floodwaters.

7. The saltwater breeding female crocodile will gather the hatchlings in her mouth.

When she hears the babies chirping, she digs them out of the nest and carefully carries them to the water's edge in her mouth. She will watch over them until they can look after themselves.

8. A saltwater male crocodile is cannibalistic.

Juvenile crocodiles are eaten by the territorial mature males. Even with the mother's care, only about 20% survive to maturity, as goannas, snakes, sharks, birds and turtles will eat them, also.

9. The saltwater crocodile has a strong muscular tail that it uses to propel itself forward

All the propulsion and steering comes from the paddling of the flattened tail.

10. Crocodile culling was last done in 1971 in the Northern Territory.

Saltwater crocodiles are now, unfortunately, becoming a public menace as their numbers increase. They have increased in the Northern Territory from about 5,000 to 80,000 in 38 years, and they are moving closer to residential areas.

Is it up to us to stay out of their way? After all, these animals held unchallenged dominion over equatorial wetlands and waterways for 65 million years after dinosaurs had gone.

It is the larger crocodile that breeds and it would be these big ones that the crocodile hunter would target. The Parks and Wildlife have taken many large dangerous saltwater crocodiles away from areas that humans also frequent. They have been known to return within a few weeks, unless they are taken to a crocodile farm. It has been said, by interested parties, that even if dozens of crocodiles were culled, how can it be guaranteed that just one crocodile will not come into a proclaimed safe area. It only takes one reptile to kill one person.

To cull or not to cull? This is the question.
