Glad to be a Bipedal Mammal

catching up on my national geographic reading, while rendering some work of course, i stumbled upon this gem:

"Her legs are soft and her body's soft, and she can't prevent being inseminated by the male. Once he's inseminated her, he'll break off his genitalia in hers, thereby plugging her up."
-Jonathan Coddington, spider expert

i complain about our species a lot, but i really am happy that i'm not this spider. they take monogamy to a whole new level.
take the angler fish. the male fuses his body to the female's. now that's commitment. if he gets sick of the woman after two months, he's s.o.l. that's for sure.
how about the praying mantis? if the male doesn't escape right after sex, the female eats his head. that's one of only a few species where a quick one-night-stand is not only acceptable, but life saving.
"that was fun but i really have to go, um, not be eaten alive."
