Octonauts episodes guide, a complete list of all animals covered in the Netflix show

Octonauts is a 23 minute TV show on Netflix. Each episodes is usually broken into two parts, with both halves highlighting a new ocean animal. There’s a team element to their science investigations, as Captain Barnacles, Lt. Kwazii, Professor Inkling, Dr. Shellington, Peso, Tweak, Sauci, and Tunip work together serving as the “octonauts” – eight navigators at the sea.

After episodic creatures come in providing a plot based on their unique species adaptations, each half of the show ends with a Creature Report – a song explaining how the creature works.
