Traumatic mating may offer fitness benefits for female sea slugs
Date:8/22/2012

Female sea slugs mate more frequently than required to produce offspring, despite the highly traumatic and biologically costly nature of their copulation, as reported Aug. 22 in the open access journal PLOS ONE.

The authors of the study, led by Rolanda Lange of the University of Tuebingen in Germany, investigated the mating behavior of a simultaneously hermaphroditic species of sea slug that mates via an extravagant ritual that involves a syringe-like penile appendage that stabs the partner to inject prostate fluids and sperm.

Surprisingly, the researchers found that the sea slugs mate more frequently than minimally required for offspring production and that both elevated and reduced mating rates are detrimental to female fitness, suggesting that there may be some additional, indirect benefits to this traumatic mating beyond reproduction.
