Definition of Term

obligate lecithotrophic live bearer
(English) A reproductive guild where eggs are fertilised internally and develop in the female until the end of the embryonic phase or later. There is no maternal-foetal nutrient transfer (yolk provides food). There is some specialisation for intrauterine respiration, excretion and osmoregulation. Weight decreases during embryonic development, e.g. Poecilia reticulata. See also facultative lecithotrophic live bearer. (See also: lecithotrophic live bearer, lecithotrophy, facultative lecithotrophic live bearer)
