Venomous Octopus Defends the Reef!

On this episode of Blue Wilderness, Mark and the crew are back at Grand Cayman Island… but this time for a space odyssey-like night dive unlike anything you’ve seen before. They are in search for something truly unique at the edge of the Caribbean Sea and the only way to find it is to dive into the dark abyss to shed light on the alien-like creatures that call this reef home, including the LARGEST venomous octopus we’ve ever featured on the Brave Wilderness channel!

    Octopus being from another planet............. really? That really lowers one's cred. Oh sure octopuses are interesting. But octopuses being aliens is ludicrous. And there is fossil record evidence for octopuses.
