The few mammals, such as deer, civet, Digs, shrews and monkeys, as wellas the birds and insects, resemble ordinary Malayan forms.
Similarly the dull coloration of the two sets of animals is very possibly procryptic and serves to hide both shrews and squirrels from enemies.
Squirrelshrews occur in the Palawan-Calamianes group, and true shrews at various points in the archipelago.
Though usually more or less cylindrical or circular in section, hairs are often elliptical or flattened, as in the curly-haired races of men, the terminal portion of the hair of moles and shrews, and conspicuously in the spines of the spiny squirrels of the genus Xerus and those of the mouse-like Platacanthomys.
Of the Insectivora numerous forms of moles, shrews and hedgehogs prevail.
