European jackal
The European jackal is the largest of the golden jackals, with animals of both sexes measuring 120–125 cm (47–49 in) in total length and 10–13 kg (20–29 lb) in body weight. One adult male in North-Eastern Italy is recorded to have reached 14.9 kg (33 lb). The fur is coarse, and is generally brightly coloured with blackish tones on the back. The thighs, upper legs, ears and forehead are bright reddish chestnut. Jackals in Northern Dalmatia have broader than average skulls, which is thought to result from human induced isolation from other populations, thus resulting in a new morphotype.
Saltwater crocodile
Saltwater crocodiles are the largest extant riparian predators in the world. However, they start life fairly small. Newly hatched saltwater crocodiles measure about long and weigh an average of . Males reach sexual maturity around at around 16 years of age, while females reach sexual maturity at and 12–14 years of age. These sizes and ages are almost identical to those at average sexual maturity in Nile crocodiles, despite that average adult male saltwater crocodiles are considerably larger than average adult male Nile crocodiles. The weight of a crocodile increases approximately cubically as length increases (see square-cube law). This explains why individuals at can weigh more than twice that of individuals at . In crocodiles, linear growth eventually decreases and they start getting bulkier at a certain point. Dominant males also tend to outweigh others, as they maintain prime territories with access to better, more abundant prey.
