Leopard - Panthera pardus
The leopard (/?l?p?rd/), Panthera pardus, is a member of the Felidae family and the smallest of the four "big cats" in the genus Panthera, the other three being the tiger, lion, and jaguar. The leopard was once distributed across eastern and southern Asia and Africa, from Siberia to South Africa, but its range of distribution has decreased radically because of hunting and loss of habitat. It is now chiefly found in sub-Saharan Africa; there are also fragmented populations in the Indian subcontinent, Sri Lanka, Indochina, Malaysia, Indonesia, and China. Because of its declining range and population, it is listed as a "Near Threatened" species on the IUCN Red List. Compared to other members of the Felidae family, the leopard has relatively short legs and a long body with a large skull. It is similar in appearance to the jaguar, but is smaller and more slightly built. Its fur is marked with rosettes similar to those of the jaguar, but the leopard's rosettes are smaller and more densely packed, and do not usually have central spots as the jaguars do. Both leopards and jaguars that are melanistic (completely black or very dark) are known as black panthers. The species' success in the wild is in part due to its opportunistic hunting behavior, its adaptability to habitats, its ability to run at speeds approaching 58 kilometers per hour (36 mph), its unequaled ability to climb trees even when carrying a heavy carcass, and its notorious ability for stealth. The leopard consumes virtually any animal that it can hunt down and catch. Its habitat ranges from rainforest to desert terrains. Leopards are agile and stealthy predators. Although smaller than other members of the Panthera genus, they are able to take large prey due to their massive skulls that facilitate powerful jaw muscles. Head and body length is between 95 and 165 cm (37 and 65 in), and the tail reaches 60 to 110 cm (24 to 43 in). Shoulder height is 45 to 80 cm (18 to 31 in). The muscles attached to the scapula are exceptionally strong, which enhance their ability to climb trees. They are very diverse in size. Males are about 30% larger than females, weighing 30 to 91 kg (66 to 200 lb) compared to 23 to 60 kg (51 to 130 lb) for females. Large males of up to 91 kg (200 lb) have been documented in Kruger National Park in South Africa; however, males in the South Africa's coastal mountains average 31 kg (68 lb) and the females from the desert-edge in Somalia average 23 to 27 kg (51 to 60 lb). This wide variation in size is thought to result from the quality and availability of prey found in each habitat. The most diminutive leopard subspecies overall is the Arabian leopard (P. p. nimr), from deserts of the Middle East, with adult females of this race weighing as little as 20 kg (44 lb). Other large subspecies, in which males weigh up to 91 kg (200 lb), are the Sri Lankan leopard (P. p. kotiya) and the Anatolian leopard (P. p. tulliana). The largest verified leopards weighed 96.5 kg (213 lb). Larger sizes reported are considered unreliable. The leopard's body is comparatively long, and its legs are short. Leopards show a great diversity in coat color and rosette patterns. Their rosettes are circular in East Africa but tend to be squarer in southern Africa and larger in Asian populations. Their yellow coat tends to more pale and cream colored in desert populations, more gray in colder climates, and of a darker golden hue in rainforest habitats. Overall, the fur under the belly tends to be lighter coloured and of a softer, downy type. Solid black spots in place of open rosettes are generally seen along the face, limbs and underbelly. Leopards may sometimes be confused with two other large spotted cats, the cheetah, with which it may co-exist in Africa, and the jaguar, a neotropical species that it does not naturally co-exist with. However, the patterns of spots in each are different: the cheetah has simple black spots, evenly spread; the jaguar has small spots inside the polygonal rosettes; while the leopard normally has rounder, smaller rosettes than those of the jaguar. The cheetah has longer legs and a thinner build that makes it look more streamlined and taller but less powerfully built than the leopard. The jaguar is more similar in build to the leopard but is generally larger in size and has a more muscular, bulky appearance.
Reticulated Python - Python reticulatus
Python reticulatus, also known as the (Asiatic) reticulated python is a species of python found in Southeast Asia. Adults can grow to at least 6.95 metres (23 ft) in length but normally grow to an average of 3-6 meters (10–20 feet). They are the world's longest snakes and longest reptile, but are not the most heavily built. Like all pythons, they are nonvenomous constrictors and normally not considered dangerous to humans. Although large specimens are powerful enough to kill an adult human, attacks are only occasionally reported. An excellent swimmer, Python reticulatus has been reported far out at sea and has colonized many small islands within its range. The specific name is Latin meaning net-like, or reticulated, and is a reference to the complex color pattern. In general, reticulated pythons with lengths more than 6 meters are rare. One of the largest scientifically measured specimen hires from Balikpapan, East Kalimantan, was measured under anesthesia at 6.95 m and weighed 59 kg after not heaving eaten for 3 months. Widely published data of specimens that were reported to be several feet longer have not been confirmed. Even what was widely accepted as the largest ever "accurately" measured snake, that being Colossus, a male kept at the Highland Park Zoo (now Pittsburgh Zoo & PPG Aquarium) in Pittsburgh, Pennsylvania during the 1950s and early 1960s, with a peak reported length of 8.7 metres (29 ft), recently turned out to be wrong. When Colossus died, April 14, 1963, its body was deposited in the Carnegie Museum of Natural History. At that time it was measured and found to be 20 ft 10 in (6.35 m) in total length, significantly shorter than the measurements previously published by Barton and Allen. Apparently, they had been adding a few extra feet to the measurements to compensate for "kinks", since it is virtually impossible to completely straighten an extremely large live python. Too large to be preserved with formaldehyde and then stored in alcohol, the specimen was instead prepared as a disarticulated skeleton. The hide was sent to a laboratory to be tanned, and unfortunately it was either lost or destroyed. Numerous reports have been made of larger snakes, but since none of these have been measured by a scientist nor have the specimens been deposited at a museum, they must be regarded as unproven and probably erroneous. In spite of a standing offer of $50,000 for a live, healthy snake over 9.1 metres (30 ft) long by the New York Zoological Society, no attempt to claim this reward has ever been made. The color pattern is a complex geometric pattern that incorporates different colors. The back typically has a series of irregular diamond shapes, flanked by smaller markings with light centers. In this species wide range, much variation of size, color, and markings commonly occurs. In zoo exhibits the color pattern may seem garish, but in a shadowy jungle environment amid fallen leaves and debris it allows them to virtually disappear. Called a disruptive coloration, it protects them from predators and helps them to catch their prey.
