Abstract: Loocomotion, including crawling (vermiform crawling and inchworm crawling), shortening (slow shortening and fast shortening), oscillating, rotating, sucker cleaning, rubbing and kissing of Haemadipsa hainana has been described.
A typical foraging behavioral sequence of a hungry worm has been described under natural conditions. The observation of the modulation of the foraging behavior has been made under laboratory conditions. A number of factors influence on this behavior, such as: 1. hunger 2. growth 3. temperature.
Ecological significance of behavioral responses to stimuli has concerned with feeding. In general, hungry H. hainana are negatively thigmotactic, positively photo tactic, negatively geotactic, attracted to warm moist air currents cuch responsibilities increase the possibility coming into contact with an host animal. The strategic postures assumed by H. hainana constitutes the initial step of the repertoire of the foraging. In general, if the H. hainana responses as thigmotactic, negatively photo tactic, positively geotactic and not attracted to warm moist air current. that is the character of a recently fed individual, which tends to retiring and to an inactive status.
