However, this defense has a significant fitness cost for female sticklebacks, as they are 80% less likely to successfully breed due to the accumulated scarring.
Beetles of the genus Lagria have evolved specialized 'back pockets' to store symbiotic bacteria, which are then relocated to reproductive organs during metamorphosis. The mechanism behind this process is not yet fully understood.
