The Kid Should See This

Witnessed during a night dive in the Lembeh Strait, a blanket octopus starts out compact and rather cute before unfurling her webbing like butterfly wings. And then she extends her flowing rainbow webs out even further. The silent 48 seconds footage was shared by NAD Lembeh Resort.

Rebecca R. Helm at JellyBiologist.com explains that these ‘blankets’ or webs are “long sheets of multi-color changing skin.” It’s like a cape attached to their dorsal and dorsolateral tentacles that, when extended, may help them look larger and more frightening to potential predators.

There are four identified species of the genus: Tremoctopus gelatus, Tremoctopus robsoni, Tremoctopus gracilis, and Tremoctopus violaceus. From the Florida Museum of Natural History:

Male and female common blanket octopuses provide one of the most extreme examples of sexual dimorphism — physical differences between females and males — in the animal kingdom, [invertebrate zoology collections manager at the Florida Museum John] Slapcinsky said. While females can grow to more than 6 feet in length, males are about an inch long and resemble larval octopuses.

Here’s another example of female blanket octopuses, a silent close-up near Romblon Island in the Philippines.
