Phyton Reticulatus

Python reticulatus is a non-venomous python species found in Southeast Asia. Adults grow to a maximum of more than 32 feet (9.75 m) in length and are probably the world's longest snakes, but not the the most heavily built. Normally not considered dangerous to man, even though large specimens are powerful enough to kill an adult and attacks are occasionally reported.

An excellent swimmer, it has even been reported far out at sea and has consequently 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.[4] No subspecies are currently recognized.[2]

Description

Adults grow to a maximum of more than 32 feet (9.75 m) in length and are probably the world's longest snakes.[5] However, they are relatively slim for their length and are certainly not the most heavily built.[6] The anaconda, Eunectes murinus, may be larger.[5]

The color pattern is a complex geometric pattern that incorporates numerous different colors. The back typically has a series of irregular diamond shapes which are 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.[5]

Habitat

Occurs in rain forests, woodland and nearby grassland. It is also associated with rivers and is found in areas with nearby streams and lakes. An excellent swimmer, it has even been reported far out at sea and has consequently colonized many small islands within its range.[5] During the early years of the twentieth century it is said to have been common even in busy parts of Bangkok, sometimes eating domestic animals.

Feeding

Their natural diet includes mammals and occasionally birds. Small specimens—up to 3–4 meters (10–14 ft) long—eat mainly rodents such as rats, whereas larger individuals switch to prey such as Viverridae (e.g. civets and binturongs), and even primates and pigs. Near human habitation, they are known to snatch stray chicken, cats and dogs on occasion. Among the largest prey items that are actually fully documented to have been taken were a half-starved old female Sun Bear of 23 kilograms that was eaten by a 6.95 m (23 ft) specimen, which took some 10 weeks to digest, as well as pigs of more than 60 kg (132 lb). As a rule of thumb, these snakes seem able to swallow prey up to ¼ their own length, and up to their own weight.[7] As with all pythons, they are ambush hunters, waiting until prey wanders within strike range before seizing it in their coils and killing via constriction.

Reproduction

Oviparous, females lay between 60 and 100 eggs per clutch. At an optimum incubation temperature of 31–32°C (88–90 °F), the eggs take an average of 88 days to hatch.[9] Hatchlings are at least 2 feet (61 cm) in length
