Description

Welcome to the Octonauts, if you've seen the show on BBC iPlayer, Netflix etc then you already know what the Octonauts are, but if you haven't, the Octonauts are a team of animated humanoid animals (penguins, cats, polar bears etc) that help marine and sub-marine life that are hurt, in danger, sick etc, although they also help each other when in need. Main Members in the actual show: Captain Barnacles [leader], Kwazii, Peso, Tweak, Dash y, Professor Inkling, Shell in g ton and T u n i b. Places to watch the show: Netflix and BBC iPlayer. PLEASE NOTE THAT PEOPLE OF ALL AGES WATCH THE SHOW. JUST BECAUSE YOU WATCH OCTONAUTS DOESN'T MEAN THAT YOU ARE UNDER THE YR OF 5. I'M MUCH OLDER AND I STILL WATCH IT FREQUENTLY.

Growth

2 measurements spanning 32 days, net +1. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 34–35 and does not start at zero.
