The mating repertoire off the Darwin's bark spider (Caerostris darwini) includes oral sexual encounters, performed obligatory before, between and after copulation.
Typical internet troll. :) This was a side-finding while conducting research of silk biomechanics of this spider species. We simply used spiders from silk experiments for mating, too...and published a funny finding. And besides, no US tax payer money was used as we're not from USA. ;)
