Homosexual rape and sexual selection in acanthocephalan worms.
Acanthocephalan males have cement glands associated with the vas deferens, secretions from which seal the female vagina with a cap after copulation and so prevent subsequent insemination. Homosexual rape results in the male victim having the genital region sealed off with cement and effectively removed from the reproductive population. Sperm and cement are transferred to females during copulation, but apparently only cement is transferred to males during homosexual rape. Acanthocephalans conform to a parental investment model, and we interpret the evolution of the cement gland and sexual behavior as the result of sexual selection.
Robinson B: Attack autotomy: a defense against predators.
The response of five species of crabs to simulated predator attack was examined. Two terrestrial species autotomized their chelipeds after the chelae were firmly attached to the predator. Selection for attack autotomy is balanced by selection for retention of the cheliped whenever the cheliped is important in social or maintenance functions.
