The adaptive advantage of leeches' attraction to certain stimuli, such as light, movement, or chemical signals, lies in their ability to locate food sources, such as blood from potential hosts. This attraction enhances their feeding opportunities, ultimately improving their survival and reproductive success. Additionally, by following specific cues, leeches can avoid unfavorable environments or predators, further increasing their chances of thriving in their habitat.

You will find them in rain forest environments and near rivers, streams, ponds but not in desert environments. Most leeches live in fresh water.TEMPERATURESThe temperatures in the leeches environment are considered temperate - generally meaning all four seasons are observed.
