The mantis shrimp episode of Octonauts is still one of my favorite all-time episodes of kids TV.

That was a great episode. They do a great job crafting stories around the featured creature. And now I have “creature report” playing in my head.

"accelerating on par with a 22-caliber bullet"

I suspect they don't literally mean to compare acceleration rates?

Googling provides all sorts of additional likely misreporting: same speed, same power, same energy.

Well good old Wikipedia gave a pretty straightforward answer of: an acceleration of 10,400 g (102,000 m/s2 or 335,000 ft/s2) and speeds of 23 m/s (83 km/h; 51 mph) from a standing start.

It’s an interesting article and I recommend reading it (it’s very short). However, it was disappointing to not have the slow motion video discussed in the article included. I followed a few links and found it:
