The Life of Crocodiles

Obscure Fact: Crocodiles DO Cry Crocodile Tears

Crocodiles have been around since the age of the dinosaurs. They survived mass extinction, and have thrived for hundreds of millions of years. 

 

The Crocodile family includes: true crocodiles, alligators and caimans, and gharial. Many may think that the alligator and crocodile are one, but the differences are in their appearance. Alligators are darker, a blackish-grey with a wider U-shaped snout, while crocodiles are lighter brown or olive green with a more pointed snout. 

 

There are salt-water and fresh-water crocodiles. Saltwater crocodiles are bigger, up to 1000 kg. Their lengths are standard, 4.3 - 5.2 meters in length. Their life spans are 70-100 years and are found in tropical areas throughout the world. 

 

There are 27 species of crocodilians whose extinction is most possible due to the activities of man. The three stages of life are birth, young, and adult. Crocodiles do not show the aging process, but usually die due to predators, starvation, accidents and disease.

 

Crocodiles are carnivores killing fish, birds, mammals and small crocodiles. They eat their prey whole, so swallow stones to aid digestion. They “cry” when they eat their victims. Their enemies are sharks, whales, and elephants. 

 

They are cold-blooded as are other reptiles, so they can’t generate their own heat. In colder weather, they hibernate (called brumation) by burrowing along a river bank or lake. They will also do this when there is a low food supply. 

 

They are nocturnal, coming out mainly at night, but can be seen other times of day. Crocodiles are intermittent, light sleepers They are most feared by people because they have the strongest bite of any animal on earth.  They do though, have weaker muscles in their jaw making it possible for a man to close their jaw with his bare hands. Their bite has a force of 5,000 lbs/sq.inch.

 

They are very fast in water, swimming up to 32 kph, staying underwater for up to an hour. This helps them catch their prey. On land, they run slower,17.6 kph. 

 

Their hearts aren’t like other reptiles. They have 4-chambered hearts like birds and mammals. 

 

Crocodiles are born into “clutches”, of 30-80 eggs. The newly hatched eggs are cared for by many parents for more than a year, protecting them and putting them into “creshes”, like daycare centers. 

 

Although crocodiles are thought to be lazy and unintelligent, the opposite is true. 

They have a communication system of chemical signals, various calls, infrasound vibrations, which are too low for us to hear, and body language. 

 

They hunt in teams, roles played according to size and age, and use sticks to lure egrets out searching for nesting material. The older crocs drive fish into shallow water to be ambushed by the youngsters.

 

The information about their intelligence, is recent and has come from those working with crocodiles such as zoologists, breeders, animal trainers and tribal hunters. 

 

Although the number of crocodiles in the 1970s was low, their protection has helped the numbers to come back to the point where culling may be necessary, especially in tourist areas where swimmers are in danger.
