Hello and welcome to Tonmo.com!

This is a fine little octopus, but doesn't quite look like briareus, which has more webbing between its arms, bulging eyes, and often a blue-green iridescent sheen. Briarius does have long arms.

Maybe you could post some more pics. Does it have two false eyespots on the mantle below the eyes? If it does, try to get a photo of those.

A fine specimen indeed but octopuses are extremely hard to identify as they are masters of contorsion, so I can't really help much as I'm not too good at ID. This whole post was just to ask, is that a volitans lion in the other tank?
Howdy! I've collected and kept a number of briareus, and the second picture in particular does indeed look very similar, with that distinctive mottled green-and-pink coloration. I would agree that the webbing doesn't look quite as prominent as you sometimes see, but they can expand and contract it to a great extent, no? So while I can't say for sure, I wouldn't rule it out, either.

If it is a briareus, they're fun guys, and pretty hardy. Remember to keep a tight lid on the tank, of course--I had one that kept escaping despite my best efforts--gave my mom quite a shock one morning when she found him staring up at her from under the dining room table! He was fine, but he eventually got too big for the tank, and had to take him back to the sea.

Good luck on keeping him!

Welcome Jon and John 8)

Id agree that the middle pic does look like briareus but they can be tricky to ID in genera....l but I'd go with that for now :smile:

i'll second the 'tight lid' note too!!!
Welcome from me, too!

I"m making a list of the octos we're keeping by species, and I'll add this one to the briareus list - does it have a name?

If you haven't already done so, you might like to add your octopus to our Octo DB, too.

why thanks!

hey well i'll try to get more pics of my littel octo. whose name btw is James bond my class calls him Mr. Bond for short. and yes thats is a lion fish in the tank next to mine. i would like to thank you all for your replies and for all your help. my tank is def shut tight as me and my father have made some modifications to the tank lid. i've been feeding him crayfish, and once i got him a couple of fiddler crabs, however he will not eat anything that is dead i tried some jumbo shrimp from the supermarket he took it from me then a few hours later i found the whole thing floating untouched. i havent done any of that adding littel guy to any list how would i go abotu doing so? again thanks for all the info and help any comment are welcome thank you

Nancy-could we possibly set up something on the site like an octopus species/photo page...with 2 or 3 pictures of each known species in their most well known color/shapbnhe patterns? That would be a great refference for site visitors.
Yes, John, good idea, we're planning to do that. I have been disappointed in what's available to identify octos. There's not even a good collection of eyespot photos. We'll start with ID sheet and care sheet for the bimac.


Hey thanks for all your help and suggestions i have more pics if anyone would like to see. and i was wondering a rubber ball in the tank bad idea as a toy? like one of those small high bouncers you get in the 25 cent machines.just for my own reference has anyone ever been bit does it hurt??
