Seems like they will get pretty big. The Fazenda Acurizal in Central pantanal was where the very first scientifically jaguar field study took place held by Dr. Schaller and Dr. Crawshaw. ''This week, the team that is in Serra do Amolar managed to put the collar on Guató, a young adult male, aged between 3 and 4 years. He weighs approximately 100 kilos and, with the monitoring by means of the radio collar with gps, will show in which area of the Serra do Amolar he usually stays more frequently.''  *This image is copyright of its original author  *This image is copyright of its original author  *This image is copyright of its original author  *This image is copyright of its original author Guató is the second big cat monitored at Serra do Amolar by IHP in Central Pantanal. The other one is the also young Joujou male, who received the collar after being rescued in very unhealthy conditions from the intense fires in the Pantanal in November last year, another male was also rescued along with Jou Jou but he unfortunaterly died while Jou Jou today is doing fine.

 Introduction The Panthera onca is the largest feline in the American continent. The body is robust, compact and muscular, with average size of 132.7 cm, the legs are strong and muscular and feet are very large. The tail is relatively short, with 57.6 cm, the average body weight is 61.4 kilograms, could reach 135 kg. (Oliveira & Cassaro 1999), and may vary depending on the habitat, sex and prey available. The length of the body of the females are 10 to 20% smaller than males (Seymour 1989). It is completely covered by black spots, which come to form rosettes of many different sizes but are generally large and with one or more black spots in its interior, the color varies between brown and yellow-ocher, tending to a brownish yellow (Oliveira & Cassaro, 2005). In captivity stress can depress the immune system of animals and thus facilitates the emergence of diseases (Birchard & Sherding 1998, Muller et al. 2005) that can cause delays in providing growth, reproductive damage and behavioral disorders (Moberg 2000), and Moreover the nutritional management of captive assumes a vital importance in preventing the occurrence of metabolic disorders and/or deficiencies. Currently, only 15% of the population (212 animals) has its origin known, representing individuals that could be used in breeding program of genetically viable. However, almost 70% of the population is over 12 years of age, and that means a group of age with low reproductive potential. (Silva & Adana, 2006). Many conservation strategies can be employed to increase the chances of survival of species threatened with extinction felidae (Filoni & Catão-Dias 2005), among which we mention, in addition to the preservation and restoration of habitat to ensure the preservation in the wild and employment of biotechnology applied to breeding in captivity, maintaining a viable population in captivity in its various aspects (medical, health, reproductive and genetic) (Silva & Adana 2006). The characterization of biometric Panthera onca can follow the development of animals, mainly of kept in captivity, justifying this study. Material and Methods The experiment was conducted in the Park Zoobotânico "Adhemar Monteiro", in the municipality of Capitão Poço, Pará State, Brazil. We used 11 animals of the species Panthera onca, five males and six females. All animals studied were adults aged between two and a half years and seven years old. To do biometrics was necessary to conduct the chemical restraint, intramuscular, using launch of the blow darts with the aid of blowpipe containing the dissociative anesthetic ketamine and an α-2 agonist, xylazine in their doses: 10 mg/kg and 1 mg/kg. Tranquilization after the animals were placed on a flat surface to determine the body condition and biometric measures. The body condition was determined by the allocation of scores, using a scale from 0 to 5 points (0 = extremely lean animal and animal fat = 5). (Mourad et al. 1989 apud Menezes in 2007). The measures were determined using a tape measure in centimeters. The following measurements were taken: average total body length (length of the tip of the tail to the tip of the snout), with the average total length of the tail length, height (length of the region's withers until the end of the previous State), the average circumference the chest, length of the tail, the average length of the head, the average circumference of the head, neck circumference average, average ear length, ear width average, the average circumference of the testes; biometrics as the front and back foot was the right length average total, average length of pad, average width of pad, the average length of more pad the third finger, middle finger width, while the teeth was the average length of canine top and bottom, right and left. After the tabulation of the data were calculated the mean, standard deviation and range of a standard deviation (upper and lower limit on the standard deviation). Results In males the average body score was 3.1 in magnitude lower(Ainf) and magnitude higher (Asup) respectively equal to 2.88 and 3.32 of a standard deviation (Dpad) equal as 0,22. In fames the average body score was 2.75 with Ainf = 2.33, Asip = 3.17 e Dpad = 0.42.

Discussion and Conclusions The mean body size without the tail length was 139.6cm for males and 131.75cm for females, results similar to those found by Oliveira & Cassaro (2005), where mention that the average body size of the Panthera onca is 132.7cm and is within the limits of range of 110.5cm and 175.4cm, described by Silva & Adania (2006). According Cassaro & Oliveira (2005) the tail is relatively short, and Silva & Adana (2006) says that on average is 57.6cm between 40cm in size and 68cm and this according to the study results in it that were on average of 54cm for females and 67 for males. The length of the body without the length of the tail in males (129.11cm-151,89cm), was relatively higher than that of females (124.77cm-138,73cm) and are in line with Seymour (1989), which mentions that the length of the body of the females are 10 to 20% smaller than the males and may vary depending on the habitat, sex and prey available, as well as the body score, which according to the classification of Mourad et al. (1989) apud in Menezes et al. (2007), was on average 3.1 for males and 2.75 for females. The study of biometric characteristics of animals in captivity is important to monitor the development of animals, because the second Campos et al. (2005), captive wild animals to impose conditions very different from those found in their environments natural. It is known that the behavior unusual species, such as excessive aggression and stereotypy, are results are considered inadequate in captivity that can provide retardation in growth and reproduction (Moberg 2000). Many activities threaten the conservation status of this species, so that the creation in captivity appears as promising options for the preservation of them in addition to the supply of animals for research and scientific advances. So monitoring through biometrics is important. The future availability of neotropical felidae success may depend entirely on the maintenance, development and reproduction of these animals in captivity or when to return to natural habitat.

@GuateGojira @Pckts
Hey guys I think it's better if we continue the jaguar size conversation here. Maybe a mod can move the posts regarding jaguar sizes on the Persian leopard thread on here? Tagging @tigerluver and @sanjay here Also regarding on the Jaguar discussion, I recall Balam saying that Joker actually measured 250 cm in total lenght in his second captures and the measurements Pckts just posted are of his initial capture where he was smaller.

Regardless I think it’s safe to say that Guates jag was also taken over the curves.

Balam had shared with me this table made comparing the measurements of Joker and Adriano to the lions and leopard in this other chart and the body lenght of Joker is estimated assuming his tail lenght remained constant from his first to second captures  *This image is copyright of its original author  *This image is copyright of its original author
