Fans of My Octopus Teacher are in for another trip under the sea. Narrated by the effortlessly funny Phoebe Waller-Bridge, Prime Video presents a new docuseries about our favorite eight-limbed mollusk. With National Geographic-like cinematography and Comedy Central-type writing, the show follows a giant Pacific Octopus named “Doris.” The story pokes into many crannies of octopus life: the female’s hunger for her mate; losing one’s way in Mexico; and finding a unicorn. Plus, Tracy Morgan weighs in. Somehow it all comes together. —Carolina de Armas
