Small Indian mongoose

The small Indian mongoose (Urva auropunctata) is a mongoose species native to Iraq and northern South Asia; it has also been introduced to many regions of the world, such as several Caribbean and Pacific islands.
== Taxonomy ==
Mangusta auropunctata was the scientific name proposed by Brian Houghton Hodgson in 1836 for a mongoose specimen collected in central Nepal. It was later classified in the genus Herpestes, but all Asian mongooses are now thought to belong in the genus Urva.
In the 19th and 20th centuries, several zoological specimens were described:
*Mangusta pallipes proposed by Edward Blyth in 1845 were mongooses observed in Kandahar, Afghanistan.
*Herpestes palustris proposed by R. K. Ghose in 1965 was an adult male mongoose collected in a swamp on the eastern fringe of Kolkata, India.
The small Indian mongoose was once considered a subspecies of the Javan mongoose (H. javanicus).
Genetic analysis of hair and tissue samples from 18 small Indian and Javan mongooses revealed that they form two clades and are distinct species.
== Characteristics ==
The small Indian mongoose's body is slender, and the head is elongated with a pointed snout. The length of the head and body is . The ears are short. The feet have five toes and long claws. Sexes differ in size, with males having a wider head and bigger bodies.
It can be distinguished from the often sympatric Indian grey mongoose (U. edwardsii) by its somewhat smaller size. Populations on islands throughout the world have increased in size and sexual dimorphism, resembling populations in the east of their range, where they have no ecological competitors.
Introduced populations show genetic diversification due to genetic drift and population isolation.
==Distribution and habitat==
The small Indian mongoose is distributed in Iraq, southeastern Iran, Afghanistan to Pakistan, India, Nepal, Bhutan, Bangladesh and Myanmar. It has been introduced to several European countries as well as islands in the Caribbean Sea, Indian and Pacific Oceans. It lives up to an elevation of .
In Iraq, the small Indian mongoose lives in the alluvial plains of the Tigris–Euphrates river system, where it inhabits riverine thickets, crop fields and orchards. It was also observed in the Hammar Marshes.
In Iran, it was recorded only in a few localities in the south and east, in particular in Kerman Province.
In Pakistan, it occurs on the Pothohar Plateau, in Sialkot District, in southeastern Azad Jammu and Kashmir and in Margalla Hills National Park.
In India, it was observed in forested areas of Panna Tiger Reserve, Guna district and Gandhi Sagar Sanctuary.
In 2016, the European Commission put the mongoose on the list of invasive alien species in the EU.
===Introduction to Caribbean===
In 1872, the first nine small Indian mongooses were introduced to Jamaica from India to control black (Rattus rattus) and brown rats (R. norvegicus) on sugarcane plantations. They reproduced within a few months.
In the 1800s, sugarcane plantations shot up on many tropical islands, including Hawaii, Fiji and Jamaica. With sugarcane came rats, attracted to the sweet plant, which caused crop destruction and loss. Attempts were made to introduce the mongoose in Trinidad in 1870 to control the rats, but this failed.
Starting in 1870, the small Indian mongoose was introduced to all of the Greater Antilles: Jamaica, Cuba, Hispaniola (in the Dominican Republic), and Puerto Rico, as well as St. Croix in the Virgin Islands, to prey upon black rats that were ravaging the sugarcane industry. Another reason for introducing the mongoose was to reduce snakes in the cane fields. While successful in reducing sugarcane damage from rats, the introduction had a negative impact on reptiles and other animals. The green iguana (Iguana iguana, also believed to be an introduced species) has been greatly reduced in number, and the ground lizard Ameiva polops was eliminated from the island of St. Croix before 1962 (but not from Protestant Cay, Green Cay, Ruth Cay, and Buck Island). Ground-nesting birds may also have been affected, as well as rock iguanas and mammals native to the region, such as hutias and solenodons. It has also been extremely successful regarding its second purpose in getting rid of snakes; on many of the Caribbean islands where it was released the native snakes have been extirpated, and now only exist on offshore islands; at least one species from St. Croix in the Virgin Islands may now be extinct.
===Introduction to Hawaii===
Accounts from the sugar industry in the early 20th century state that the introduced mongooses were effective at reducing the number of rats, mice, and insects. However, the mongooses have been deleterious to native birds, which evolved in the absence of mammalian predators, and also prey on the eggs of endangered sea turtles.
Only the islands of Lana'i and Kaua'i are thought to be free of mongooses. There are two conflicting stories of why Kaua'i was spared. The first is that the residents of Kaua'i were opposed to having the animals on the island, and when the ship carrying the offspring reached Kaua'i, the animals were thrown overboard and drowned. According to the other story, upon arriving on Kaua'i one of the mongooses bit a dockworker, who, in a fit of anger, threw the caged animals into the harbor to drown.
===Introduction to Okinawa===
In Japan, the mongoose was introduced onto Okinawa Island in 1910 and Amami Ōshima Island in 1979 in an attempt to control the population of the venomous snake Protobothrops flavoviridis, an endemic species, and other pests, but they have since become pests themselves."The Small Asian Mongoose introduced to the Island of Okinawa and Amami-Oshima: The Impact and Control Measure."

== Behaviour and ecology ==
The small Indian mongoose uses about 12 different vocalizations.
== Diet ==
In Pakistan, the small Indian mongoose feeds primarily on insects including dragonflies, grasshoppers, mole crickets, ground beetles, earwigs and ants. It also preys on lesser bandicoot rat (Bandicota bengalensis), short-tailed bandicoot rat (Nesokia indica), Asian house shrew (Suncus murinus), Indian gerbil (Tatera indica) and house mouse (Mus musculus). Scat collected in Pir
Lasura National Park contained remains of black rat (Rattus rattus), small amphibians, reptiles, small birds, seeds of grasses and fruits.
=== Diseases ===
Small Indian mongooses in northern Okinawa Island were found to be infected with Leptospira and antibiotic-resistant strains of Escherichia coli.
The small Indian mongoose is a major rabies vector in Puerto Rico, but transmission to humans is low.
