Ptyas mucosa, commonly known as the Oriental rat snake, [2] dhaman or Indian rat snake, [4] is a common non-venomous species of colubrid snake found in parts of South and Southeast Asia. Dhamans are large snakes. Typical mature total length is around 1.5 to 1.95 m (4 ft 11 in to 6 ft 5 in) though some exceed 2 m (6 ft 7 in).
Gonyosoma oxycephalum, known commonly as the arboreal ratsnake, the red-tailed green rat snake, and the red-tailed racer, is a species of snake in the family Colubridae. The species is endemic to Southeast Asia .
This reliance underscores the critical role of native plants in supporting ecological food chains. The distinction between generalists and specialists is not limited to animals. For example, some plants require a narrow range of temperatures, soil conditions and precipitation to survive while others can tolerate a broader range of conditions.
Food chain in a Swedish lake. Osprey feed on northern pike, which in turn feed on perch which eat bleak which eat crustaceans.. A food chain is a linear network of links in a food web, often starting with an autotroph (such as grass or algae), also called a producer, and typically ending at an apex predator (such as grizzly bears or killer whales), detritivore (such as earthworms and woodlice ...
Rats are a common food item for snakes, both in the wild, and as pets. Adult rat snakes and ball pythons , for example, are fed a diet of mostly rats in captivity. Rats are readily available (live or frozen) to individual snake owners, as well as to pet shops and reptile zoos, from many suppliers.
Elaphe is a genus of snakes in the family Colubridae. Elaphe is one of the main genera of the rat snakes, which are found in many regions of the northern hemisphere. Elaphe species are medium to large constrictors by nature.
While rat snakes are being hunted during the day, being more active at night due to warmer temperatures may allow rat snakes to be less vulnerable to predation from hawks. [9] A warming climate also enhances food digestion in rat snakes thereby making them more efficient, which enables rat snake individuals to grow larger in size and allowing ...
Molecular studies of phylogeny indicate that hutias nest within the Neotropical spiny rats . [5] Indeed, the hutia subfamily, Capromyinae, is the sister group to Owl's spiny rat Carterodon. [6] In turn, this clade shares phylogenetic affinities with a subfamily of spiny rats, the Euryzygomatomyinae. [6]
