KLEPTOPARASITISM Meaning and
Definition
-
Kleptoparasitism is a biological term used to describe a behavior observed in certain animal species where one individual steals or takes food from another individual of a different species or the same species. It is a form of parasitism in which the kleptoparasite benefits by acquiring food or resources without having to perform any effort or expenditure of energy.
The term "kleptoparasitism" is formed by combining two Greek words: "klepto" meaning "to steal" and "parasitism" meaning a non-mutual relationship where one organism benefits at the expense of another. Kleptoparasitism is commonly observed in birds, particularly among avian predators and scavengers.
In kleptoparasitic interactions, the kleptoparasite may take prey that has been captured by another individual, steal food from nests, or snatch food from the mouths or talons of other animals. This behavior can provide a significant advantage to kleptoparasites, as they can obtain food quickly and easily without having to search for or capture it themselves.
While kleptoparasitism is considered a form of parasitic behavior, it should be noted that it is distinct from classical parasitism, where the parasite typically lives in or on the host organism for an extended period and extracts nutrients or resources from it. Kleptoparasitism is more focused on the exploitation of opportune moments to acquire food from others.
Etymology of KLEPTOPARASITISM
The word "kleptoparasitism" is derived from the Greek words "klepto" meaning "to steal" and "parasitism" meaning "a symbiotic relationship in which one organism benefits at the expense of another".
The prefix "klepto" comes from the Greek word "kleptes", which means "thief" or "robber". It is also related to the Greek word "kleptein", meaning "to steal".
The term "parasitism" comes from the Greek word "parasitos", which refers to a person who eats at another's table, a guest-friend, or a sycophant. Over time, the term "parasitism" has specifically come to signify a relationship where one organism, the parasite, benefits at the expense of another organism, the host.
