Some 117 species of [[reptiles]] have been recorded in Kakadu. Being cold-blooded, these animals rely on heat from an external source such as the sun to regulate their body temperature. This is not to say that reptiles are active only during the day; in fact, few snakes can withstand Kakadu's midday heat and most are active at night. Since the arrival of the [[cane toad]] in the park, many populations of reptiles have crashed. Reptiles which were once a common sight such as large [[goanna]]s, [[eastern brown snake]]s, [[Acanthophis|death adder]]s and many others were rare by 2010.<ref>[[ABC News (Australia)|ABC News]]: [http://www.abc.net.au/news/video/2010/10/15/3040035.htm ''Cane Toad impacts in the Top End'']</ref> The iconic [[frill-necked lizard]] has also significantly dropped in numbers.

Two species of [[crocodile]] occur in Kakadu: the [[freshwater crocodile]] (''Crocodylus johnstonii'') and the estuarine, or [[saltwater crocodile]] (''C. porosus''). Freshwater crocodiles are easily identified by their narrow snout and a single row of four large boney lumps called "scutes" immediately behind the head. Estuarine crocodiles do not have these scutes and their snout is broader. The maximum size for a freshwater crocodile is 3 metres, whereas a saltwater can exceed 6 metres.

On October 22, 2002, a twenty-four-year-old female [[Germans|German]] tourist was killed by a saltwater crocodile assault while swimming in Sandy billabong with other foreign backpackers including her sister.<ref>{{cite news|url=https://www.irishtimes.com/news/woman-who-escaped-bali-bomb-killed-by-crocodile-1.443360|title=Woman who escaped Bali bomb killed by crocodile|newspaper=The Irish Times}}</ref><ref>{{cite web|url=http://www.cnn.com/2002/WORLD/asiapcf/auspac/10/22/australia.crocattack/|title=CNN.com - German tourist taken by crocodile - Oct. 22, 2002|website=www.cnn.com}}</ref>
