Aliens in Georgia

Today's Times reports that "Alien worms spread terror in Georgia".

I know, you'll think I'm on one of my politician-mocking shticks. Not so. This really is about worms. Nothing to do with the fact that Georgia stole millions of Trump's votes. Nothing to do with Rudy Giuliani. Real, animal worms. To be precise, the Hammerhead Worm. Yes, even more opportunities for poor taste jokes.

The hammerhead worm, so called because of its distinctive shape,

is a member of the Bipalium genus of large predatory land planarians. What is a planarian? It's a flatworm of the class Turnbellaria. For those of you who have long forgotten your biology lessons, here are some reminders of biological classifications and rankings:

  • A class contains orders
  • Orders contain families
  • Families contain genuses - correct plural but more usually genera
  • Genera contain species
  • The Bipalium genus contains approximately 50 species
I researched a number of reports of this but sadly none of them identified the species of the individual in question. Shoddy journalism; do your research, people!

Anyway, these guys are only "alien" in the sense that a gardener in Georgia said "it looked like an alien". I could find no information about what actual aliens have been seen in Georgia, to enable our gardening friend to make his judgment.

The worm, however is indigenous to the USA.

Hammerhead worms are carnivorous and prey mostly on other worms, particularly earthworms. They produce tetrodotoxin, the same deadly neurotoxin produced by pufferfish, according to a study from Utah State University.

The Times reports that James Murphy from the University of Georgia "emphasised that there were only a few of the worms. As long as you are not eating numerous worms it is not something to be concerned about."

Wait, who are you talking to? There are people in Georgia who eat worms? Are you serious? Maybe he's from the University of Georgia Department of Comedy. Here we were, having serious discussions about biology, and you lower the tone? Come on! Be serious.

No animals were harmed in the writing of this blog post.
