The small Asian mongoose (Herpestes javanicus) is a species of mongoose found in the wild in South and Southeast Asia. It has also been introduced to various parts of the world. The western subspecies group is sometimes treated as a separate species, the Indian mongoose or small Indian mongoose (Herpestes palustris).

Description[edit]

This species of mongoose is sympatric with Herpestes edwardsii in much of its native range and can be readily distinguished from the latter species by its much smaller size. The body is slender and the head is elongated with a pointed snout. The lengths of the head and body is 509-671mm. The ears are short. They have five toed feet with long claws. The sexes differ in size with males having a wider head and bigger size.[2]

They use about 12 different vocalizations.[3]

Distribution and habitat[edit]

This species occurs naturally throughout most of southern mainland Asia, from Iraq to China, as well as on the island of Java, at altitudes up to 2200 m. It has also been introduced to dozens of islands in the Pacific and Caribbean (including Saint Lucia, Jamaica and Puerto Rico), as well as a few in the Indian Ocean and Mediterranean, as well as to mainland Venezuela. It is capable of living among fairly dense human populations.

Mongooses live in scrublands and dry forest. On Pacific Islands they live in rainforests as well.

Diet[edit]

These mongooses mostly eat insects but are opportunistic feeders and will eat crabs, frogs, spiders, scorpions, snakes, and birds and bird eggs.

Behavior and reproduction[edit]

Mongooses are mostly solitary although males will sometimes form social groups and share burrows. Pregnancy duration is up to 49 days. A litter can consist of 2–5 young.

Introduction to Hawai'i[edit]

The 1800s was a huge century for sugar cane, and plantations shot up on many tropical islands including Hawai'i, Fiji and Jamaica. With sugar cane came rats, attracted to the sweet plant, which ended up causing crop destruction and loss. Attempts were made to introduce the species in Trinidad in 1870 but this failed.[4] A subsequent trial with four males and five females from Calcutta however established in Jamaica in 1872. A paper published by W. B. Espeut that praised the results intrigued Hawaiian plantation owners who, in 1883, brought 72 mongooses from Jamaica to the Hamakua Coast on the Big Island. These were raised and their offspring were shipped to plantations on other islands.[5] Populations that have been introduced to these islands show larger range sizes than in their native ranges.[6] They also show genetic diversification due to drift and population isolation.[7]

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. A second story tells that on 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 St. Croix[edit]

The small Asian mongoose was introduced to St. Croix in 1884, also to prey upon black rats (Rattus rattus) that were ravaging the sugarcane industry. This introduction has had a negative impact on many species of reptiles. For instance, the green iguana (Iguana iguana) has been greatly reduced in number and the St. Croix ground lizard (Ameiva polops) was eliminated from the island of St. Croix (but not from Protestant Cay, Green Cay, Ruth Cay, and Buck Island) before 1962. Ground nesting birds have also been greatly affected. Mongooses have even preyed upon fawns of white-tailed deer (Odocoileus virginianus)[8]

Introduction to Okinawa[edit]

The mongoose was introduced onto Okinawa Island in 1910 and Amami Ōshima Island in 1979 in an attempt to control the population of venomous snakes (habu (波布?)) and other pests; an invasive species, they have since become pests themselves.[9][10]

Invasive species[edit]

The mongoose introduction did not have the desired effect of rat control, either in Hawai'i or St. Croix. The mongoose hunted birds and bird eggs, threatening many local island species. The mongooses bred prolifically with males becoming sexually mature at 4 months and females producing litters of 2–5 pups a year.

Mongooses can carry leptospirosis.[11]
