Sandy,
Those are the best pictures of Monterey's octopus in her cave that I have seen. Light helps, huh?
I have met her "behind the scenes" and she is very large and so cool. She will stick her arms out of the tank and feel-around with the tentacles to see what she can find. Like all octopus she is a real escape artist so her cave-tank is sealed tight. She is a real favorite of the staff so she has lots of attention.
LOVED seeing your pictures.
