Leeches possess unique anticoagulant properties in their saliva, with herudin being the most notable for its ability to inhibit thrombin, a key player in blood coagulation. This fascinating compound has been synthesized for medical use, particularly for patients who cannot tolerate heparin. Additionally, leeches produce multiple bioactive substances that prevent platelet aggregation, leading to prolonged bleeding from their bites, which is both a curious and useful aspect of their biology.
