s, thylacines had a very large rear pad and four obvious front pads, arranged in almost a straight line. The hindfeet were similar to the forefeet but had four digits rather than five.

The cast shows the plantar pad in more detail and shows that the plantar pad is tri-lobal in that it exhibits three distinctive lobes. It is a single plantar pad divided by three deep grooves. The distinctive plantar pad shape along with the asymmetrical nature of the foot makes it quite different from animals such as dogs or foxes.

, making it unable to run at high speed. It could also perform a bipedal hop, in a fashion similar to a kangaroo—demonstrated at various times by captive specimens. Guiler speculates that this was used as an accelerated form of motion when the animal became alarmed. The animal was also able to balance on its hind legs and stand upright for brief periods. Observers of the animal in the wild and in captivity noted that it would growl and hiss when agitated, often accompanied by a threat-yawn. During hunting, it would emit a series of rapidly repeated guttural cough-like barks (described as "yip-yap", "cay-yip" or "hop-hop-hop"), probably for communication between the family pack members. It also had a long whining cry, probably for identification at distance, and a low snuffling noise used for communication between family members. Paddle (2000), pp. 65–66. Some observers described it as having a strong and distinctive smell, others described a faint, clean, animal odour, and some no odour at all. It is possible that the thylacine, like its relative, the Tasmanian devil, gave off an odour when agitated. Paddle (2000), p. 49.

Ecology and behaviour

Little is known about the behaviour of the thylacine. A few observations were made of the animal in captivity, but only limited, anecdotal evidence exists of the animal's behaviour in the wild. Most observations were made during the day, whereas the thylacine was naturally nocturnal. Those observations, made in the twentieth century, may have been atypical, as they were of a species already under the stresses that would soon lead to its extinction. Some behavioural characteristics have been extrapolated from the behaviour of its close relative, the Tasmanian devil. The thylacine was a

hunter, spending the daylight hours in small caves or hollow tree trunks in a nest of twigs, bark, or fern fronds. It tended to retreat to the hills and forest for shelter during the day. and hunted in the open heath at night. Early observers noted that the animal was typically shy and secretive, with awareness of the presence of humans and generally avoiding contact, though it occasionally showed inquisitive traits. At the time, much stigma existed in regard to its "fierce" nature; this is likely to be due to its perceived threat to agriculture.

Reproduction

There is evidence for at least some year-round breeding (cull records show joeys discovered in the pouch at all times of the year), although the peak breeding season was in winter and spring. They would produce up to four joeys per litter (typically two or three), carrying the young in a pouch for up to three months and protecting them until they were at least half adult size. Early pouch young were hairless and blind, but they had their eyes open and were fully furred by the time they left the pouch. The young also have their own pouches but are not visible until they are 9.5 weeks old. After leaving the pouch, and until they were developed enough to assist, the juveniles would remain in the lair while their mother hunted. Paddle (2000), p. 60.

In 2018, Newton et al. collected and CT-scanned all known preserved thylacine pouch young specimens to digitally reconstruct its development throughout its entire window of growth in the mother's pouch. This study revealed new information on the biology of the thylacine, including the growth of its limbs and when it developed its 'dog-like' appearance. It was found that two of the thylacine young in the Tasmanian Museum and Art Gallery (TMAG) were misidentified and of another species, reducing the number of known pouch young specimens to 11 worldwide. One of four specimens kept at Museum Victoria has been serially sectioned, allowing an in-depth investigation of its internal tissues and providing some insights into thylacine pouch young development, biology, immunology and ecology.

Feeding and diet

The thylacine was exclusively carnivorous. In captivity, thylacines had a clear preference for birds (particularly chickens). In the wild, large ground-dwelling birds (such as

. Another study in 2020 produced similar results, after estimating the average thylacine weight as about rather than , suggesting that the animal did indeed hunt much smaller prey. However, an earlier study showed that the thylacine had a bite force quotient of 166, similar to that of most quolls; in modern mammalian predators, such a high bite force is almost always associated with predators which routinely take prey as large, or larger than, themselves. If the thylacine was indeed specialised for small prey, this specialisation likely made it susceptible to small disturbances to the ecosystem. Analysis of the skeletal frame and observations of the thylacine in captivity suggest the species were pursuit predators, singling out a prey item and pursuing them until the prey was exhausted. However, trappers reported it as an

. The animal may have hunted in small family groups, with the main group herding prey in the general direction of an individual waiting in ambush. Although the living grey wolf is widely seen as the thylacine's counterpart, the thylacine may have been more of an ambush predator as opposed to a pursuit predator. In fact, the predatory behaviour of the thylacine was probably closer to ambushing felids than to large pursuit canids. Its

Relationship with humans

Captivity

By the beginning of the 20th century, the increasing rarity of thylacines led to increased demand for captive specimens by zoos around the world. Despite the export of breeding pairs, attempts at having thylacines in captivity were unsuccessful, and the last thylacine outside Australia died at the London Zoo in 1931.

by around 40,000 years ago, with the notable exceptions of several kangaroo species and the thylacine. A 2010 paper examining this issue showed that humans were likely to be one of the major factors in the extinction of many species in Australia although the authors of the research warned that one-factor explanations might be over-simplistic. The thylacine itself likely neared extinction throughout most of its range in mainland Australia by about 2,000 years ago. However, reliable accounts of thylacine survival in South Australia (though confined to the "thinly settled districts" and

in mainland Australia because the dingo might have competed with the thylacine and devil in preying on the native hen. The study also proposes that an increase in the human population that gathered pace around 4,000 years ago may have led to this. A counter-argument is that the two species were not in direct competition with one another because the dingo primarily hunts during the day, whereas it is thought that the thylacine hunted mostly at night. Nonetheless, recent morphological examinations of dingo and thylacine skulls show that although the dingo had a weaker bite, its skull could resist greater stresses, allowing it to pull down larger prey than the thylacine. The thylacine was less versatile in its diet than the omnivorous

. Their ranges appear to have overlapped because thylacine

remains have been discovered near those of dingoes. The adoption of the dingo as a hunting companion by the indigenous peoples would have put the thylacine under increased pressure. A 2013 study suggested that, while dingoes were a contributing factor to the thylacine's demise on the mainland around 3,000 years ago, larger factors were the intense human population growth and technological advances and the abrupt change in the climate during the period.

Extinction in Tasmania

They were rarely sighted during this time but slowly began to be credited with numerous attacks on sheep. This led to the establishment of bounty schemes in an attempt to control their numbers. The

-like disease that affected many captive specimens at the time. Paddle (2000), pp. 202–203. A study from 2012 also found that were it not for an epidemiological influence, the extinction of thylacine would have been at best prevented, at worst postponed. "The chance of saving the species, through changing public opinion, and the re-establishment of captive breeding, could have been possible. But the marsupi-carnivore disease, with its dramatic effect on individual thylacine longevity and juvenile mortality, came far too soon, and spread far too quickly." Whatever the reason, the animal had become extremely rare in the wild by the late 1920s. Despite the fact that the thylacine was believed by many to be responsible for attacks on sheep, in 1928 the Tasmanian Advisory Committee for Native Fauna recommended a reserve similar to the

The animal, believed to have been a male, had been seen around Batty's house for several weeks. Work in 2012 examined the relationship of the genetic diversity of the thylacines before their extinction. The results indicated that the last of the thylacines in Tasmania had limited genetic diversity due to their complete geographic isolation from mainland Australia. Further investigations in 2017 showed evidence that this decline in genetic diversity started long before the arrival of humans in Australia, possibly starting as early as 70–120 thousand years ago.

until its death on the night of September 6, 1936. Its source has long been disputed. Until recently, Elias Churchill was regularly quoted as being the captor, but there appears to be little evidence to support this claim. Two more recent candidates are far better placed evidentially as the probable source – the Kaine capture near Preolenna in 1931 and the Delphin capture near Waratah in 1930. The thylacine died on the night of 6–7 September 1936. It is believed to have died as the result of neglect—locked out of its sheltered sleeping quarters, it was exposed to a rare occurrence of extreme Tasmanian weather: extreme heat during the day and freezing temperatures at night. Paddle (2000), p. 195. This thylacine features in the last known motion picture footage of a living specimen: 45 seconds of black-and-white footage showing the thylacine in its enclosure in a clip taken in 1933, by naturalist

. In the film footage, the thylacine is seen seated, walking around the perimeter of its enclosure, yawning, sniffing the air, scratching itself (in the same manner as a dog), and lying down. Fleay was bitten on the buttock whilst shooting the film. In 2021, a digitally colourised 80-second clip of Fleay's footage of Benjamin was released by the National Film and Sound Archive of Australia, to mark National Threatened Species Day. The digital colourisation process was completed by a Paris-based company, based on historic primary and secondary descriptions to ensure an as exact colour match as possible. The location of remains of a later Thylacine have been discovered in a cupboard in the Tasmanian Museum and Art Gallery in December 2022. Frank Darby, who claimed to have been a keeper at Hobart Zoo, suggested Benjamin as having been the animal's pet name in a newspaper article of May 1968. No documentation exists to suggest that it ever had a pet name, and Alison Reid (''de facto'' curator at the zoo) and Michael Sharland (publicist for the zoo) denied that Frank Darby had ever worked at the zoo or that the name Benjamin was ever used for the animal. Darby also appears to be the source for the claim that the last thylacine was a male. Paddle (2000), pp. 198–201. Robert Paddle was unable to uncover any records of any Frank Darby having been employed by Beaumaris/Hobart Zoo during the time that Reid or her father was in charge and noted several inconsistencies in the story Darby told during his interview in 1968. The sex of the last captive thylacine has been a point of debate since its death at the Beaumaris Zoo in Hobart, Tasmania. In 2011, a detailed examination of a single frame from the motion film footage confirmed that the thylacine was male. When frame III is enlarged the

When the offer closed at the end of June 2005, no one had produced any evidence of the animal's existence. An offer of $1.75 million has subsequently been offered by a Tasmanian tour operator, Stewart Malcolm. Trapping is illegal under the terms of the thylacine's protection, so any reward made for its capture is invalid, since a trapping license would not be issued.
