The scientist returned to the same spot the next afternoon. By that time, the corpse was bloated and had begun to rot and smell.

But even the stench did not discourage another male black-and-white tegu from attempting to have sex with the dead body—this time for nearly an hour.

During this time, the new male embraced the dead female and bit her head, another courtship behavior. He rested on her body from time to time, taking breaks from the exhausting sexual activity, before finally flicking his tongue on the corpse and leaving, according to the study, published in January in the journal Herpetology Notes.
