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.
Temeraire (series)
Dragons in this category are enormous, although size varies greatly between heavyweights of different breeds (20–50 ton weight range). The largest British heavyweight, the Regal Copper, weighs a maximum of 50 tons, can be up to long and have a wingspan of . There are also unidentified breeds of dragons and cross-breeds known to be even larger, such that their size can only be described as "immense". A typical middling heavyweight Chinese Celestial/Imperials and the French "Chanson-de-Guerre", both of which weigh in around 20-25
 tons at a minimum. The Turkish Kazilik is the only known fire-breathing heavyweight. Heavyweight eggs are extremely valuable, often said to be more valuable than gold per pound (a Regal Copper egg is said to be worth 56,000 pounds, an enormous amount of money in the early 19th century). Kazilik eggs command incredible value, with the British paying the Ottoman Empire half a million pounds for three eggs (most of which was allocated for the Kazilik). Typically heavyweights are the most long-lived of all dragons, some are known to live for hundreds of years, but by contrast, they take much longer to recover from illness or disease than middle or lightweights.
