In this episode, Clara and Emily take a dive into the world of cuttlefish... but Clara spends the first five minutes thinking we're talking about pufferfish. Learn why these marine invertebrates are known as the chameleons of the sea and get a glimpse at their strange mating rituals in this week's episode!
