Description    Venomous mammals are rare. The platypus, found in Australia, delivers venom by a spur on the medial aspect of the tarsus. Only mature males are dangerous. There is local pain and swelling at the injection site. The short-tailed shrew BLARINA BREVICAUDA is venomous and there is the potential for toxicosis following a bite although there appear to be no published reports of this.
