. The TV series was based on the children's books written by Vicki Wong and Michael Murphy of Meomi Design Inc.

The Octonauts follows an underwater exploring crew made up of stylized anthropomorphic animals, a team of eight adventurers who live in an undersea base, the Octopod, from where they go on undersea adventures with the help of a fleet of aquatic vehicles.

The subject matter is reminiscent of a blend of Star Trek

 and Jacques Cousteau. Although science fiction as regards its technology, the exotic creatures and locations that the crew encounter are real marine animals in their natural habitats.

Books

The original books were first published in the USA by Immedium in 2006, and were republished in the UK by Harper Collins in 2009.

Four titles by Meomi have been published
The Octonauts and the Only Lonely Monster, about an Architeuthis (Giant Squid),
The Octonauts and the Sea of Shade, about a world where everyone's shadows have gone missing,
The Octonauts and the Frown Fish, about a glum-looking catfish

, and
The Octonauts & the Great Ghost Reef, about a dying coral reef.


The books have been well-received, with reviewers on Amazon giving them an average 4.6 out of 5 stars rating. Reviewers (who typically bought the books for children aged 2–5 after seeing the TV series) said they were very well liked, however some thought the stories "quite weird" compared to the TV series, with several doubting whether the animals depicted in the books were real. Some also found the language a bit difficult for 4 year olds, and the changed named of one character (Dashi/Sauci) caused confusion.

.

The TV show is episodic, with each ten minute episode seeing them encountering an unusual but real sea creature as they explore strange underwater worlds. Often they must discover a vital biological or behavioural fact about that creature to rescue it or themselves from danger. The stories usually feature three main characters: Captain Barnacles, Kwazii and Peso, with the other five Octonauts acting in supporting roles.

In the TV series they use five sea-creature inspired underwater vehicles called GUP-A to GUP-E, and a pedal driven GUP-F, driven by Captain Barnacles and Kwazii, which appears in Episode 10 of Series 1 ("The Speedy Sailfish").

The Opening Theme Tune finishes with the chant "Explore! - Rescue! - Protect!" and this informs the narrative of all the episodes.

The TV series was well received when shown on CBeebies in the UK. According to the authors' website it was the No.1 pre-school age show in the UK, and the only pre-school show to be ranked in the top ten by older audiences (aged 4–15).
It has been rated 8.2 out of 10 on IMDb.

TV spin-off books

A series of shorter books based on individual episodes from the TV series is being published by Simon and Schuster.
These titles can be distinguished by the "As seen on TV" moniker on the covers and are not written or illustrated by Meomi. The books have the same titles as the episodes they are based on.
