Avoidance of filial cannibalism by sexual and clonal forms of Poeciliopsis (Pisces: Poeciliidae)
Article Abstract:
A study on filial cannibalism among fish in the genus Poeciliopsis shows that neonates of P. lucida, a non-cannibalistic species, do not avoid their female parent. Neonates of cannibalistic form, P. monacha and the hybrid P. monacha-lucida, exhibit clear avoidance. Examinations show that avoidance behavior in the hybrid P. monacha-lucida is inherited from genetic variance that existed in their P. monacha sexual ancestors. Parental avoidance also increases with size at birth, showing an anti-cannibalistic strategy in nature.

Sexual cannibalism in an orb-weaving spider Argiope aemula
Article Abstract:
Sexual cannibalism in orb-weaving spider, Argiope aemula, is a form of terminal paternal investment. Females weigh at least ten times as much as the males. The males of A. aemula mate only once in their life time using their palps. The males escape from the female unscathed after the first insertion. The males are motionless before the females due to fierce resistance. The males are generally eaten after the second copulation with the same female.
