Traumatic Insemination

The Turbellaria flatworm was one inspiration for the post Sugar Bugs, and also for the mated pair forming the 'gy' in the site logo.

Many other species engage in this practice.

"The evolutionary origins of traumatic insemination are disputed. Although it evolved independently in many invertebrate species, traumatic insemination is most highly adapted and thoroughly studied in bedbugs, particularly Cimex lectularius. Traumatic insemination is not limited to male-female couplings, or even couplings of the same species. Both homosexual and inter-species traumatic inseminations have been observed. Traumatic insemination has been likened to human sadomasochism, stabbing, and rape behaviors. However, such coercive sex practices are common in nature and provide sperm competition, enable bypassing the mating plug, and overcome female resistance to being mated." -Wikipedia

Basic Anatomy

Simply lovely

"Anchored to the cerebral keel in the pectoral armature, the “vertebrate” brain is actually made up of two separate organs that work in tandem. One of these is a more-or-less “ordinary” brain, made up of a dense knot of fibrous nerves. The other is a maddening structure known as the worm basket; a sac filled with an extremely convoluted bundle of microscopic tubules. Within these tubes lies a series of millions of glands and vesicles that seem to communicate with each other with a cryptic alphabet of chemicals and protein equivalents. Scans have revealed that the tubes in the worm basket squirm, twist, corkscrew and coil against themselves when Snaiadi “vertebrates” are dreaming, or engaging in intellectually demanding tasks."
