Need Help in identifying new octopus

We just got this octopus 4 days ago and now have a couple of pics to share to see if anyone can help identify it. Sorry the pics aren't better, but I think they show enough detail to at least rule out some species! :smile:

Here is what I know about it: It was shipped from New York. Supplier said it was from Indonesia and more colorful and outgoing than others he usually gets. It's about 8 inches long with maybe a 2+ inch mantle. Legs are long and stringy, maybe 6 inches or longer depending on if it's stretched out. I noticed that its mantle seems to be shaped like a cone often.

It came out in the early morning after it was placed in tank the night before. I watched as it explored tank and even flattened out and turned the color of the sand. Then it changed back to a darker brown with a reddish tint and kept exploring. When I lift rock it is under it is a medium color brown with bright green splotches all over it.

It actually came out and climbed on my hand once. I noticed this morning that it had eaten a hermit crab last night at some point! Yay!!! I realize it is probably "older", however the supplier said he thought it would grow to about 22 inches. Am wondering what species it might be, how old it might be and if there is any way to guess the sex of it. Also, once I get an idea of species, am interested in suggestions for more permanent tank size, shape, etc...

May I just say that this is THE coolest classroom EVER!!! :cool2: I love how in the second picture, none of the children seem even remotely interested in the fact that there is an OCTOPUS being dangled about their heads! (I'm sure it was just the timing of the photo).
Looking forward to seeing more pictures Kim! :smile:

Thanks! We do have a lot of fun! Funny, I noticed the kids lack of interest after posting that pic! They had already had their fill of looking at an octopus by the time we took this pic. Haha!

Kids have the attention span of ... well an octopus :biggrin2: The "cone head" look is one we see from a lot of species and often involves a "skunk streak" of white or brown down the middle of the "cone" I don't know of an agreed upon interpretation but I suspect it is one of aggravation.

Not lifting rocks to find it is a good idea. They need to be secure that they can hide so leaving them alone in their dens is advised. Interesting animal but I have no good guess for species. I do suspect something in the Macropus complex though, based upon it color and long arms. This would make it a nocturnal and animal so you may not see much of it during the day.

As for identifying the sex, we have no distinct markings for females but the third arm to the right (clockwise as you orient your eyes with the octopuses) will often be curled. This specialized arm will have a suckerless tip and a channel (not always easy to see) to deliver spermatophores to the female. You may also notice several enlarged suckers near the body on any of the front four arms.

Thanks for your input. I won't bother the den any more! :smile: So far you are right about it only coming out at night. It comes out in evening and is out all night. I swear that last night it was watching the TV! LOL I am going to try and get better pics soon. I haven't used a flash because I don't want to upset it. Is that correct? Some of the pictures on this site are so good! By the way, it has eaten 2 hermit crabs! Was worried that it might not eat. Oh yes, it now has a name... Ziggy! My foreign exchange student from Austria named it!
