Shrewlike Rat
The shrewlike rats, genus ''Rhynchomys'', also known as the tweezer-beaked rats are a group of unusual Murinae, Old World rats found only on the island of Luzon in the Philippines. They look a great deal like shrews and are an example of convergent evolution. Shrewlike rats evolved to be Vermivore, vermivores and insectivores feeding on Soft-bodied organisms, soft-bodied invertebrates associated with leaf litter. Characteristics The snout and rostrum (anatomy), rostrum are very long. Eyes are small. Head and body is 18.8–21.5 cm with a tail 10.5–14.6 cm. Only two molar (tooth), molars are present on each side of the upper and lower jaws; these are small and peg-like. Incisors are described as Sewing needle, needle-like and mandibles as delicate. Their characteristic method of locomotion has given rise to the epithet "hopping rats," describing their method of pouncing on an earthworm prey before it can slide back into its hole. Distribution Shrewlike rats are fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Murinae
The Old World rats and mice, part of the subfamily Murinae in the family Muridae, comprise at least 519 species. Members of this subfamily are called murines. In terms of species richness, this subfamily is larger than all mammal families except the Cricetidae and Muridae, and is larger than all mammal orders except the bats and the remainder of the rodents. Description The Murinae are native to Africa, Europe, Asia, and Australia. They are terrestrial placental mammals. They have also been introduced to all continents except Antarctica, and are serious pest animals. This is particularly true in island communities where they have contributed to the endangerment and extinction of many native animals. Two prominent murine species have become vital laboratory animals: the brown rat and house mouse are both used as medical subjects. The murines have a distinctive molar pattern that involves three rows of cusps instead of two, the primitive pattern seen most frequently ...

Mount Labo
Mount Labo, is a potentially active stratovolcano in the province of Camarines Norte, in the Bicol Region (Region V), on Luzon Island, in the Philippines. It is located at the northwest end of the Bicol Peninsula. Physical features Labo is a forested andesitic stratovolcano, surrounded by numerous andesitic to dacitic satellite lava domes. It has an elevation of asl. Base diameter of this complex volcano is . Labo is thermally active with both warm and hot springs. Economic activities Mount Labo has been the object of an extensive geothermal exploration program. Eruptions Mid-Pleistocene eruptions beginning about 580,000 years ago formed lava domes on the northern side of the complex. The present edifice was formed beginning about 270,000 years ago, and flank lava dome emplacement took place from about 200,000 to about 40,000 years ago. The latest activity from Mt. Labo produced pyroclastic flows from the summit cone about 27,000 years ago. There have been no eruptions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mammals Described In 2019
A mammal () is a vertebrate animal of the Class (biology), class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three Evolution of mammalian auditory ossicles, middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors Genetic divergence, diverged in the Carboniferous Period over 300 million years ago. Around 6,640 Neontology#Extant taxon, extant species of mammals have been described and divided into 27 Order (biology), orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, Mole (animal), moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the Artiodactyl, even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including Felidae, ...
