The female black bear can give birth while she hibernates. The fat-tailed dwarf lemur prepares to hibernate by storing its fat reserves in its tail - doubling its body weight. Why do these animals go to such extremes? Sheena Lee Faherty details why animals hibernate. Lesson by Sheena Lee Faherty, animation by Rémi Cans. Thank you so much to our patrons for your support!
