Crikey! Crocodiles are one of the most fascinating creatures of planet Earth and have been accepted as descendants of the much feared dinosaurs. They adapted on the verge of dinosaur extinction and the adaption has been made possible through the presence of limbs and a snout. Crocodiles are known for their long life and the longest life of a crocodile has been reported to be 115 years. This crocodile died in 1997 in a Russian zoo.
As it turns out, this crocodile was not actually lucky. Crocodiles can actually live up to 100 years and this is the reason why, it is very difficult to determine their age. Crocodiles have lamellar growth in their teeth and bones, which is a ring like structure. These rings symbolise growth rate and occur once or twice in a year, according to Live Science.
According to Crocodilian, ideally, scientists take a young crocodile and start observing his lamellar growth. But this is not a great method. A crocodile in captivity may not live up to his full expected life, as compared to a crocodile which grows in a natural habitat. On the other hand, a natural habitat crocodile may be never spotted again. This is the problem with determining age when it comes to crocodiles.
According to several researches conducted around the world, it turns out that the crocodiles which live the longest are also the largest. This means that the size of the crocodiles is directly proportional to how long a crocodile will grow up to be.
The researches have also estimated that the average life of any crocodile ranges between 30-40 years, and it can extend up to 70 years, in some cases even 100. Some crocodiles around the world have gone beyond 100 and made world records. C. Porosus however remains to be the longest living crocodile species.
