It may impact on agricultural activities and it is known to threaten species of amphibians, birds, lizards, snakes and bats.īoa constrictors can carry viruses such as Inclusion Body Disease and Ophidian Paramyxovirus, which are fatal to native Australian snakes as they have no resistance to the diseases. The Boa constrictor can represent a threat to humans, particularly small children, as well as domestic pets. Boa constrictors feed on a wide variety of vertebrates including small mammals, birds and their eggs, small lizards and occasionally amphibians with larger sized Boa constrictors able to feed on larger animals. The Boa constrictor’s jaws are lined with small, hooked teeth which are used for grabbing and holding prey while it is wrapped around and suffocated by the snake. The Bomford Risk Assessment Model classifies the Boa constrictor as a ‘Serious’ establishment risk for Australia.īoa constrictors have been bred and actively distributed by the pet industry with the species now kept both legally and illegally in captivity around the world. The Bomford Risk Assessment Model 1 provides a model of the risk to Australia of non-indigenous animals based on data collected for introduced species in Britain and the United States of America using parameters including taxonomy, climate matching, geographic range, and success of establishment elsewhere. Impactīoa constrictors have a proven record of success as an invasive species having successfully established non-native pest populations in locations such as Dade County, Florida in the USA and Cozumel Island, Mexico. However, in addition to the browns and creams seen in Boa constrictor colouration, carpet pythons typically have an olive green colouration. Native carpet pythons reach similar sizes to Boa constrictors and also have blotches, stripes or cross bands. The coloured patterns aid in camouflaging the snake under natural conditions, allowing the species to evade detection and assist it to hide from and ambush its prey. The Boa constrictor generally displays distinctive patterns on the body, of jagged lines, ovals, diamonds and circles, with typical markings often described as “saddles”. Colouration of the Boa constrictor species ranges widely with tan, green, red and yellow colouration combinations. The Boa constrictor is non-venomous and has an arrow-shaped head. The Boa constrictor is considered to be one of the world’s largest snake species with an average length of around 3m. There is no reason to kill a New Hampshire snake.The Boa constrictor ( Boa constrictor) originates from Central and South America, including northern Mexico and north-western Argentina, where a total of 10 subspecies of the Boa constrictor occur. If you think you see a timber rattlesnake, please leave it alone, and let us know. New Hampshire has only one venomous snake, the timber rattlesnake, which is protected by law. Information and photographs were compiled for all of New Hampshire’s native snakes to aid in this identification process. The first step to reporting a sighting is accurately identifying the species. ![]() The New Hampshire Fish & Game maintains a database of all reptile and amphibian reports through its Reptile and Amphibian Reporting Program (RAARP). Overall, snakes are poorly studied and basic distribution and life history information is lacking. Five of the 11 species (i.e., timber rattlesnake, eastern hognose snake, northern black racer, smooth green snake, and ribbon snake) were identified as species in greatest need of conservation in New Hampshire’s Wildlife Action Plan completed in the fall of 2005. Other species like the timber rattlesnake are extremely rare and are now state protected. ![]() Some of these species, such as the garter snake are common and widespread across the state. There are 11 species of snakes that are native to New Hampshire. Don't Be Rattled (May/June 2019 NH Wildlife Journal).
