Octo-moms...as in real octopus moms...echidnas & more on NatGeo!
It looks like a cross between a shrew and a bath brush, but could an echidna actually hurt you? Plus reader questions about the octopus mom who set a record of guarding eggs for more than four years, fish behavior and how species get classified as endangered in my column, Ask Your Weird Animal Questions: Venomous Mammals, Octopus Mothers, on National Geographic. I'm happy to answer your questions, too! Just sign in to NatGeo and post your questions in the comments or tweet me at @LizLangley
