Which mammal injects venom through its teeth?

Solenodons, short-tailed shrews, the Eurasian Water Shrew, and the European Mole inject venom into prey by biting it; the venom is transferred through teeth. Male platypuses inject venom through spurs on their back legs; female platypuses and both sexes of echidnas also have these spurs, but they cannot inject venom.
