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 .
American alligator
The American alligator is a relatively large species of crocodilian. On average it is the second largest species in the family Alligatoridae, behind only the black caiman. As with all crocodilians, and as opposed to many mammals where size eventually diminishes with old age, healthy American alligators may continue to expand throughout their lives and the oldest specimens are the largest. Very old, large male American alligators reach an expected maximum size of up to in length, weighing up to , while females reach a maximum of . On rare occasions, a large, old male may grow to an even greater length. During the 19th and 20th centuries, larger males reaching have been reported. The largest reported individual size was a male killed in 1890 on Marsh Island, Louisiana, and reportedly measured at in length, but no voucher specimen was available, since the American alligator was left on a muddy bank after having been measured due to having been too massive to relocate. If the size of this animal was correct, it would have weighed approximately . Large adult American alligators tend to be relatively robust and bulky compared to other similarly length crocodilians, for example captive males measuring were found to weigh (although captive specimens may outweigh wild specimens due to lack of hunting behavior and other stressors). The largest American alligator ever killed in Florida was , as reported by the Everglades National Park. The largest American alligator scientifically verified in Florida for the period from 1977 to 1993 was reportedly and weighed , although another specimen (size estimated from skull) may have measured .
