Two recent discoveries underscore the dangers of sex in the animal kingdom. First up, the squid:

After their three-hour sex sessions, dumpling squid are so exhausted that they can swim only half as long as before their sexual workout, an exhaustion that might limit their search for food and leave them more vulnerable to predators, Australian researchers reported this week.

And the fly:

Typically, the flies were nearly invisible to the bats’ sonar at night, but this all changed when flies got busy. During sex, male flies produce noisy broadband buzzing sounds that bats are able to hear and home in on. About five percent of copulating flies were attacked by bats, and most of them were eaten.
