The female Blanket Octopus, a clip from Oceans

Update: The original video will only play on YouTube. It’s been replaced with another blanket octopus clip.

Like an elusive, caped creature in the ocean, a female blanket octopus glides through the water. We know this video is of a female of the species because she is around two meters (6.6 feet) long. In contrast, the male blanket octopus is less than 3 centimeters wide.

The difference in males and females of a species is called sexual dimorphism, and can include size, coloring or ornamentation, form or structure, and behavior. A few examples of this include peacocks, peacock spiders, birds of paradise, lions, elk, and even humans. The BBC is a good start for further viewing.

This clip is from Oceans, a French documentary film by Jacques Perrin (released in the US by Disneynature). It also includes incredible footage of a ‘fish tornado’ morphing into a fish bait ball.
