The hedgehogs of the sea: echinoids are spiky, spiny, pokey, be-toothed, venomous, mysterious, gorgeous evolutionary marvels. And Dr. Rich Mooi of the California Academy of Arts & Sciences is one of their biggest champions. Come stroll through the offices for a face-to-face encounter with this infectious expert. We talk sand dollars, uni, doves of peace, fire urchins, kelp forests, tiny hats, butt placement, foot eyes and how to find your niche, even if it’s miles below the surface on a rotting log. And bonus at the very very end: a chat about the practicalities of owning an electric vehicle with a few sci-comm up-and-comers. Learn More About Dr. Rich Mooihttps://www.calacademy.org/learn-explore/science-heroes/rich-mooiA donation went to to: https://www.calacademy.org/Follow the California Academy of Arts and Science at twitter.com/calacademy A donation went to to: https://www.calacademy.org/Follow the California Academy of Arts and Science at https://www.twitter.com/calacademy   Sponsors of OlogiesTranscripts and bleeped episodesSmologies (short, classroom-safe) episodesBecome a patron of Ologies for as little as a buck a monthOlogiesMerch.com has hats, shirts, masks, totes!Follow @Ologies on Twitter and InstagramFollow @AlieWard on Twitter and InstagramSound editing by Jarrett Sleeper of MindJam MediaTranscripts by Emily White of The WordaryWebsite by Kelly R.
