Cassius is the most enormous living crocodile and is likely more significant than we thought.

The saltwater crocodile, which is believed to be around 120 years old, entered the record books in 2011., It was nearly 18 ‘ (5.48 meters) long. However, his keepers haven’t measured his size since then, so Cassius may have gotten bigger.

“It’s very possible Cassius may have grown bigger since 2011, however we have not attempted to remeasure him,” Toody Scott,e caretaker of Cassius on behalf of Marineland Crocodile Park in Australia, has told Guinness World Records. “We may attempt this in the near future to provide some insight into growth rates of large crocodiles or of course if his record was being challenged.”

Saltwater Crocodiles ( Crocodylus porosus) can grow up to 23 feet (7 m) long, and a second record-holder is a 50-year-old captive animal from the Philippines called Lolong that measures over 20 feet (6.17 meters). Lolong was caught in 2012 and was able to replace Cassius as the record holder, but the crocodile passed away a year later when it flipped over with a gastric ulcer. Cassius was reintroduced as the world’s most colossal captained croc.

While he’s probably been around two times the length of time, Cassius probably won’t catch the pace of his predecessor. “As crocodiles get larger than 5 m [16.4 feet], growth rates seem to slow to as little as 1 cm [0.4 inch a year] and in many instances the crocodile may stop growing,” Scott declared.

However, Cassius could even be missing some inches because of his injuries in the wild. When the researchers first caught him in 1984, the massive crocodile was fighting with other crocodiles for the territory of his home and also attacked boat engines, which resulted in him losing parts of his tail and snout. The missing body parts weren’t considered in the measurements of his 2011 body and could have added six to ten inches (15 to 25 centimeters) to his height, as per Guinness World Records.

According to the size of crocodiles living within the Marineland park since the park’s inception, Cassius’ keepers estimate that the massive crocodile was born in 1903. This year also marks the 120th birthday celebration of the saltwater giant, and his keepers believe Cassius could have “years to come. “

“Becoming a Guinness World Record holder certainly shot Cassius to ‘croc-stardom,'” Scott declared
