E9: Life in the Sloth Lane
Hi everyone and welcome to Life in the Sloth Lane! Buckle up because students
Caroline Briggs, Madison Gallaher and Sarah Shea are about to take you on a crazy
adventure exploring the world of Folivora! Folivora is composed of the two and three
toed modern day sloth, as well as extinct species such as the giant ground sloth. Join
us as we drive along the phylogenetic roadways and explore what makes sloths so
unique. How are they able to thrive living such a slow paced lifestyle? Tune in to find
out!

Sloth safari, I love this!
ReplyDeleteI wish I could get as much sleep as a sloth.
I really enjoyed the sloth safari theme, it kept me engaged throughout the podcast. Also, the fact that it can take a sloth up to a month to digest a single meal is insane. Imagining a creature like this being the size of an elephant is unreal to think about.
ReplyDeleteI had no clue sloths couldn't shiver! I wonder how we'll find out which of the hypotheses on sloths movement being so slow is true. Perhaps it's a combination of both hypotheses. Really cute podcast, very fitting for a really cute animal!
