The Mysterious Blanket Octopus

The world underwater is probably much more mysterious than what it apparently seems to be. The diversity of marine animals found in the oceans is a matter of great curiosity for marine biologists and sea divers. While we know much about whales, dolphins, and penguins, the mystery surrounding octopuses arouses great interest to know more about these supremely intelligent sea creatures. Even with eight suckered arms and some interesting adaptations, octopuses have been mentioned only in a few mythological texts! But they have been featured in several thrillers, sci-fi movies, and novels.

Interesting Facts about the Blanket Octopus

If by any chance, you ever go scuba diving in the Great Barrier Reef, in Australia, you’ll probably be mesmerized by the colorful marine life swimming along with you. But if you stumble across a blanket octopus, you’ll have a rare experience indeed.

This is because they are very rarely seen alive by biologists all across the world. Most cases, only the dead bodies are found collected in plankton nets.

Moreover, their rare presence is also due to the reason that they are known to be secretive in nature traveling far off into the oceans. One of the most fascinating, eye-popping and bizarre blanket octopus facts is related to reproduction of this species. But before we switch over to that fact, let us know more about this mysterious sea creature.

Large Females

Most species experience what is known as sexual dimorphism, which simply means one sex is larger than the other. For a blanket octopus, however, this difference is incredible. Females of this species can grow to over 6.5 foot in length, while the male counterparts are only around an inch long, fully matured. Males have a short lifespan and they are always in an endeavor to find a potential partner to mate. In case they find a female blanket octopus, they will present their tentacles stored with sperms to the female and then die shortly. The females keep the tentacles within their body and at appropriate times, use it for reproduction.

Defense Mechanism

The “blankets” of a blanket octopus are not for warmth or to aid in mobility. The blanket octopus actually uses them for defense. When fleeing from a potential threat, the octopus unfurls its blankets to appear larger. If that trick doesn’t work, the octopus can then detach the blankets so the pursuing threat will become entangled.

Another interesting fact about the blanket octopus is their unique defense mechanism. When jellyfish or better known as the Portuguese man-of-war, pass these octopuses, they will tear off the poisonous tentacles of the jellyfish and carry it along with them to chase away predators. They’re generally immune to the poisonous sting of the jellyfish tentacles!

No Ink

Unlike other species of octopus, the blanket octopus does not eject ink to defend itself. This fact is not surprising when one considers the myriad of other defense techniques the blanket octopus is armed with.
