"True rats" are members of the genus "Rattus", the most important of which to humans are the black rat, "Rattus rattus", and the brown rat, "Rattus norvegicus". Many members of other rodent genera and families are also referred to as rats, and share many characteristics with true rats. - Rodents (from Latin "rodere", "to gnaw") are mammals of the order Rodentia, which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents; they are found in vast numbers on all continents except Antarctica. They are the most diversified mammalian order and live in a variety of terrestrial habitats, including human-made environments. - Palawan (Pron. , from ), officially the Province of Palawan , is an archipelagic province of the Philippines that is located in the Mimaropa region. It is the largest province in the country in terms of total area of jurisdiction. Its capital is the City of Puerto Princesa, but it is governed independently from the province as a highly urbanized city. - The black rat ("Rattus rattus"), also known as the ship rat, roof rat, house rat, is a common long-tailed rodent of the genus "Rattus" (rats) in the subfamily Murinae. The species originated in tropical Asia and spread through the Near East in Roman times before reaching Europe by the 1st century and spreading with Europeans across the world. - Palau (historically Belau or Pelew), officially the Republic of Palau, is an island country located in the western Pacific Ocean. The country contains approximately 250 islands, forming the western chain of the Caroline Islands in Micronesia, and has an area of . The most populous island is Koror.

Quezon City is not located in and should not be confused with Quezon Province, which was also named after the president. It is the largest city in Metro Manila in terms of land area and most populated local government unit in the country. - The South China Sea is a marginal sea that is part of the Pacific Ocean, encompassing an area from the Karimata and Malacca Straits to the Strait of Taiwan of around . The area's importance largely results from one-third of the world's shipping sailing through its waters and that it is believed to hold huge oil and gas reserves beneath its seabed. - The brown rat, also referred to as common rat, street rat, sewer rat, Hanover rat, Norway rat, brown Norway rat, Norwegian rat, or wharf rat ("Rattus norvegicus") is one of the best known and most common rats. - Indonesia (or ; Indonesian: ), officially the Republic of Indonesia, is a unitary sovereign state and transcontinental country located mainly in Southeast Asia with some territories in Oceania.

They occupy a vast variety of habitats on every continent except Antarctica. Some authorities have placed all members of this group into a single family, Muridae, due to difficulties in determining how the subfamilies are related to one another. The following taxonomy is based on recent well-supported molecular phylogenies. - The genus Chrotomys contain a unique group of rodents found only in the Philippines , specifically the islands of Luzon , Mindoro , and Sibuyan . Instead of being predominantly herbivorous or omnivorous like other murines , these rats feed predominantly on invertebrates although they do eat some vegetable matter . This vermivory is probably the result of a rat - like animal moving into an ecological niche usually filled by shrews . Shrews and other insectivores are absent on these Philippine islands . - Great Britain, also known as Britain, is a large island in the north Atlantic Ocean off the northwest coast of continental Europe. With an area of , Great Britain is the largest European island and the ninth-largest in the world.

Asia covers an area of , about 30% of Earth's total land area and 8.7% of the Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Asia is notable for not only its overall large size and population, but also dense and large settlements as well as vast barely populated regions within the continent of 4.4 billion people. - Mindoro is the seventh-largest island in the Philippines. It is located off the coast of Luzon, and northeast of Palawan. The southern coast of Mindoro forms the northeastern extremum of the Sulu Sea.
