Genus of rodents
Chrotomys Luzon striped rat (Chrotomys whiteheadi ) Scientific classification Domain: Eukaryota Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Rodentia Family: Muridae Subfamily: Murinae Genus: Chrotomys Thomas, 1895 Type species Chrotomys whiteheadi
Species Chrotomys whiteheadi Chrotomys mindorensis Chrotomys gonzalesi Chrotomys silaceus Chrotomys sibuyanensis
Chrotomys silaceus (upper animal) 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.
Taxonomy Rickart et al. (2005) found that C. mindorensis , C. whiteheadi , and C. gonzalesi are closely related whereas C. silaceus and C. sibuyanensis represent earlier offshoots of the genus. Several authors place C. silaceus in the genus Celaenomys , but Rickart et al. (2005) suggest that neither genetic nor morphometric distance warrant it.
These rats are considered "old endemics" and are probably the result of one of the first colonisations of the Philippine islands. Other murines colonised the islands at a later time and are more closely related to mainland murines.
