Assassin Bugs
The assassin bug is one creature who definitely deserves its name. Despite its diminutive stature, it kills about 12,000 people every year. The stealthy little bug has a distinct thin, neck-like structure which connects its slender head to the rest of its body. It has a beak with three segments which it uses to pierce its prey. While the bite itself is not deadly, they carry a protozoan parasite which imparts the Chagas disease to its victims. Once the disease reaches the chronic stage, it can lead to heart symptoms, and can even cause heart failure due to the presence of the parasite in the organ’s muscle fibers.
