Physarum polycephalum, aka "The Blob," is on display at the Paris Zoological Park now through Nov. 3.

Exploiting its reported fondness for oats, back in 2016 scientists put an impediment—caffeine, which the blob does not enjoy—between some slime mold and its serving of grains. This is Slime Molds 101.

When let loose to feed, the slime mold branched out in a network similar to Tokyo's existing train system, connecting the food piles with impressive efficiency. What has hundreds of sexes and excels at math? Enter The Blob – a yellowish chunk of slime mould set to make its debut at the Paris Zoological Park on Saturday.

What’s more, slime molds like The Blob — which are one cell composed of many small units — can communicate with one another and learn new information about their environments. Slime molds are not new, but they're worthy of your attention. The slime mold, Physarum polycephalum, also has almost 720 sexes, can move without legs and heals itself in two minutes if cut in half.

But wait, it gets weirder.
