What even *is* a jellyfish?! How do they eat? What are they made of? Can we eat them? Your new favorite Medusologist, Dr. Rebecca Helm, is a ray of human sunshine in the depths of the deep sea. Truly one of the finest biology conversations you may ever hear. Get ready for  PacMan ghosts, pet jellyfish, the biggest and smallest jellies, new band names, live medusas, secret formulas to incite jellyfish puberty, and the lengths that she will go to to see a jelly bloom. Next week, your ears will fill with Toxinology as we explore jellyfish VENOM.  Dr. Rebecca Helm’s Jellyfish Blog and website: https://jellybiologist.com/ Follow her at Twitter.com/rebeccarhelm or twitter.com/rebeccarhelm A donation went to The Vancouver Aquarium: www.vanaqua.org Look at their Jelly Cam! https://www.vanaqua.org/visit/live-cams-jelly-cam Sponsor links: kiwico.com/ologies For more links: alieward.com/ologies/medusology Transcripts & bleeped episodes at: alieward.com/ologies-extras Become a patron of Ologies for as little as a buck a month: www.Patreon.com/ologies OlogiesMerch.com has hats, shirts, pins, totes and uh...bikinis?
