In part 3 of this series, I attempted to feed a slug, Megapallifera mutabilis, to my "pet" planarian Bipalium adventitium. The planarian refused. In the comments, Megan P. suggested that I repeat the experiment with baby slugs. You see, as long as it is in the name of science, we can even feed babies to predators. We are collecting data here.
I thought Megan's idea was worth a try, but I was freshly out of baby slugs. Luckily, Megan had some and was willing to part with a few. So, last Thursday I visited her lab at the University of MD and returned home with 3 juvenile Philomycus carolinianus, another native species in our favorite slug family the Philomycidae. And early this evening, I offered them to El Depredador that had been waiting patiently in the basement.
So far the slugs have survived. But the night is young and there is plenty of time for a surprise pharynx eversion.
To be continued.
