An octopus is a wonderful, intelligent alien with eyes like ours, skin that can see, arms that taste and feel and act on their own with independent brains. The combined octopus brain has more neurons than a human brain!
Octopuses can live out of water if they stay wet. They can chase prey up into the shallows and onto land. Octopuses routinely escape tanks and wander about out of water. Some even run like cats! One octopus escaped from her tank, ate rare fish in another tank, and returned to her "home". She traveled secretly, at night, when people were gone. She was seen on video when a monitor was installed to learn what was happening to the fish.
After baby octopuses hatch, most types do not migrate and return; they stay where they hatched. I borrowed that part of Dragon Dreamers from sea turtle life cycles. (Scientists recently learned that, with some types of sea turtles, the mother helps and guides her hatchlings to the sea.)
Not as much is known about octopus interactions in their natural setting. Octopuses are very smart and curious. Some mimic other sea creatures so perfectly that you can't tell the difference! The starfish you see could be a shape-shifted, color-changed octopus! In tanks they form friendships with people, so it seems they could form friendships with other octopuses. The pod was my idea; it suited the fantasy and allowed more interactions. I truly enjoyed exploring the undersea world in bit.ly/TheDragonDreamer
