Captain Barnacles is the captain of the Octonauts and a brave polar bear. Along with being the captain, Barnacles is also the strongest member of the crew and he's demonstrated that in a number of different episodes. He's also one of the most level-headed crew members, often dismissing Kwazii's outlandish stories about sea monsters and ghosts. His crew has great respect for him.
It's also been revealed that he rather fancies playing the accordion. Though he has trouble playing it well, as shown in The Octonauts and the Orcas. So far, the only ones to appreciate the music have been a pod of Orcas. He is also an oceanographer and a map finder.
He is also very fond of the Arctic Circle as that is where he grew up (he possibly grew up there because polar bears live there in real life).
In both the UK and US versions, Captain Barnacles speaks with a British accent.
As shown in the Manatees, he is somewhat dishonest, when he lies about having his right hand stuck in a giant clam. It is unknown if he was putting the manatees first or trying to prevent himself from being embarrassed.
It is revealed in The Underwater Caves of Sac Actun, that he has claustrophobia after being stuck inside an ice cave hole as a cub. Being in the narrow Sac Actun Cave tunnels reminded him of how he came to fear tight, closed-in spaces as a young cub. It is interesting to note that at the time, Kwazii and Dashi knew about this, while Peso did not. However, he manages to overcome his fear with the help of Peso's bravery and the other Octonauts.
Captain Barnacles has white fur and a blue uniform with a matching hat. He's also always seen wearing his Octo-Compass on his belt. His earlobes are white, though the insides are bright blue as well as his muzzle.

Captain Barnacles sounds off the Octo-Alert to gather the Octonauts to the main deck to help an underwater creature. He does not usually sound the Octo-Alert himself, he sends the person closest to him to do it, or the one that has a problem. When he calls for the launch bay he runs down the hallways and jumps down chutes with Kwazii and Peso. In one of the episodes, he is seen weightlifting, which gives him his strength. He has a habit of saying "Octonauts, to the..." when he hears the Octo-Alert, even if he wasn't the one who sounded it (episodes "The Kelp Forest Rescue", "The Crafty Cuttlefish", "The Mantis Shrimp", etc.). Sometimes when the power happens to be off, and Barnacles needs to use the Octo-Alert, he gets the Vegimals to do their own version of it.
