Golden jackal
The golden jackal is similar to the gray wolf but is distinguished by its smaller size, lighter weight, more elongated torso, less-prominent forehead, shorter legs and tail, and a muzzle that is narrower and more pointed. The legs are long in relation to its body, and the feet are slender with small pads. Males measure in body length and females . Males weigh and females weigh . The shoulder height is for both. In comparison, the smallest wolf is the Arabian wolf ("Canis lupus arabs"), which weighs on average .
Crowned eagle
The crowned eagle is a very large eagle. Measuring from in length, it is the fifth longest extant eagle in the world. The female, at a weight of , is around 10–15% larger than the male, at a weight of . An average body mass of was given in one account. Elsewhere, an average of has been claimed. Overall, they are the 9th heaviest living eagle species. The wingspan typically ranges from . The largest authenticated wingspan for a female was , with a claim of wingspans of up to needing confirmation. This eagle's wingspan is quite short for the bird's size, being around the same mean width as that of a tawny eagle ("Aquila rapax") or a short-toed snake eagle ("Circaetus gallicus"), species that weigh about half as much as a crowned eagle. However, the somewhat boxy and rounded wings are quite broad, being broader than, for example, the much longer-winged golden eagle ("Aquila chrysaetos"). The wing morphology of the species gives it maneuverability in its densely wooded environment. The wing chord measures , with a median of in males and in females. While it, on average, is less heavy and has a smaller wingspan than the often sympatric martial eagle, its average total length exceeds that of the martial eagle thanks to its much longer tail. The crowned eagle's tail is from long, with a median of in males and in females. The bill is of a medium size relative to its body size, with one large museum specimen's bill measuring in length from the gape, in culmen length and in bill depth.
The tarsus is of a modest length for a raptor of its size, at , and is clearly shorter than that of martial eagle. However, the feet and legs are visibly thicker and heavier than those of the martial eagle and the talons are apparently quite massive in both length and width. While no comprehensive measurements of the talon size of wild crowned eagles are known, one female museum specimen reportedly had a hallux-claw (or hind claw, which is the largest talon on accipitrids) of , while another female was measured at 5 years of age, the age of sexual maturity, in the hallux-claw and an adult male measured . These figures put their talon size as around the same size as the largest golden eagles and close to those of a mid-sized harpy eagle. Some captive crowned eagles have been credited with a hallux-claw length of up to , although, much like a single report of captive harpy eagles with a hallux-claw, no such outsized talons are known to have been confirmed. In a small sampling of large, forest-dwelling raptors, the front-left talon of the crowned eagle, at , was around one cm less than that of a harpy eagle or the huge, recently extinct Haast's eagle ("Harpagornis moorei") and slightly smaller than those of the Philippine eagle ("Pithecophaga jefferyi"). Considering a big female of these species can weigh up to twice as much as an average crowned eagle may illustrate the relative largeness of the crowned eagle's talons.
