#TIL from https://www.iheart.com/podcast/stuff-to-blow-your-mind-21123915/episode/the-monstrefact-auto-ghouls-of-groombridge-station-115302035/ that shrews, unable to hibernate, shrink their brains, spines and other organs to reduce energy needs during the winter, then regrow it during the spring.
(Side note: shrews are also one of the very few venomous mammals.)
Imagine that - shrinking, and making yourself dumber, to get through lean times. There's a good sci-fi story in that somewhere.
