The red octopus is a species known as cepahlopod
Really?  That's so cool.  I never thought an octopus could be so incredibly interesting.  The man in the movie cared deeply about her.
They can blend into their surroundings with their movement
They showed that in the movie.  She could practically disappear and even change colors.
They can squirt black ink when they are in danger
And the octopus in the film had a leg bitten off but it grew back!!
They are one of few mammals to be able to problem solve and pattern recognition
You have got to see that movie!  She was problem solving and learning.  She was even playing with some fish.  
They blend into their surroundings by changing color
And they have like 1/2 million eggs after mating.  I wonder how many survive out of that many?
