THE quadrupeds which compose this small but numerous group live
principally upon insects, and have their molar teeth studded with sharp
points. The habits of the different families are extremely varied. Some
for instance, like the Hedgehog, seek their food on the ground, while
others like the Tupaia, hunt for it on trees. The Moles, on the other
hand, find their subsistence deep in the soil, and live entirely under
the ground; while the Desmans, and some species of the Shrew Mice live
in or near the water.
The Insect-eaters are usually divided into three families—the various
kinds of Moles, which are too well known to require special description;
the Shrew Mice and their numerous small relatives, including the Water,
the Oared and the Elephant Shrew, the Desmans, etc.; and the
Hedgehogs—including the Long-eared and the Common Hedgehog, the Tupaia,
and other members of this curious prickly family.
