Flehmen: [see also: testing, vometonasal organ] (Rasmussen, et al 1982; Schultze & Rasmussen 1999b: 1269) In elephants, it refers to the placing of the trunk-tip in the mouth after olfactory testing of another elephant or its by-products. Presumably done in order to determine the sexual status (i.e. estrous or non-estrous) of the female. Mostly done by males to females, but may also be performed by females to males or other females.
