Picked up this guy the other day to replace my A. Aculeatus, any ideas on ID?
I kind of want to say O. vulgaris, but I'm curious to see what others have to say.
I was thinking that myself, but it is still small outstretched the Octo is about the size of my hand with the tentacles longer and thinner than my fingers. This is the best I can describe it. Tomorrow morning I will try to get a pic with something in the frame for sizing. The shop that I got it at just got a Hawaii shipment in so I'm kinda thinking bimac?
Hmmmm, wouldn't the webbing between the arms be much larger if it were to be a bimac? Have you seen any false eye spots or any other distinct indicators?
No eye spots or other indications that aren't visible in the pics, so far it only comes out in the early morning, no sightings at night. It will stay out for a few hours after the lights are on in the morning though. I've been feeding it half a silverside every morning for the last three days. I will get a pic with it beside a pop can for size too.
Look at El Diablo's journal (I don't have a link, just do a quick search or look at the List of Journals for 2010 or 2011), see if he looks similar.
Interesting.... I have a small octo from mexico that sometimes shows that same coloration. Where did you get him? do you know where it was caught?
need more pics for a better ID.
could be Cyanea from hawaii - although it lacks the white spots.
could be vulgaris from carribean
also looks like Mimus from central and south america.
I dont think it is a bimac.
I found the el diablo thread, it looks very similar to some of the pics. I noticed Lmecher refers to el diablo as O.vulgaris in the thread title but later in many posts says O.briareus, so which was it? It almost touched me yesterday while feeding, it would reach out towards my hand then jet away and repeat, hopefully as it gets more comfortable it will interact more.
Link here for interested onlookers:
...adding *this* thread to the homepage slideshow - thanks for posting the great pics!
I believe at first he was thought to be a briareus, but later determined to be a vulgaris.
Thanks for posting the link Tony!
el Diablo was definitely NOT briareus. Evidence was pretty strong for O. vulgaris. I want to look at the crescent that we have posted somewhere as I am not sold on vulgaris ... but then it took me a very long time to decide Little Bit had no better id.
Here is a grouping of LittleBit's "looks" as a young octo and a Video here that shows her looking lot like your photo. She was from the Caribbean and would have been quite small for a vulgaris but that is the most likely species. With the exception of el Diablo, one trait we have seen is that they are quite aggressive, even if they want to interact. They also appear to be a lot stronger than similarly sized O. briareus. She was the only octopus to leave hickys on my hand (photo in the journal). In spite of being a bit rough, she is at the top of my favorites and I would dearly love to keep another.
As for a Hawaiian species, try a Google scan on both common (crescent) and species (hawaiiensis) preceeded by "octopus" for a look at a few photos. Julian (Julie) was likely a crescent and I know there was on other likely candidate but I can't find the post. Ah, here is the other and it has a description of markings to look for to help ID
What worries me a little is that O. cyanea also comes to mind ... How big is your tank?
Here is a vid I took yesterday. I'm leaning towards joubini after seeing little bit. My tank is 24x24x18 approx 42g.
LOL, except ultimately I decided LittleBit was NOT joubini. She grew way too large. My best assumption was a small vulgaris. The key on this one is probably the eyes and section around the beak that one would want to call a neck. The arms have been too curious in the wrong places and it is hard to determine much about their length and thickness as I think more than the one showing regrowth have been food for other creatures.
I'm happy no matter which it turns out to be, and if it is vulgaris I get to build a new tank :)
Looks like a juvenile O.vulgaris. If is males get about 4 lbs. ,female about 6 lbs. So a bigger tank would be a good idea. I keep one in 600 gallon tank, with a total water volume 800 gallon system, and still need to do weekly water changes and gravel vacs.Having a really protein skimmer will too. At that size I would offer food twice a day, and try a more invert based diet(shrimp,clams,mussels,ect.) Good luck and enjoy.
I've been feeding frozen silversides. Tomorrow I will grab a bag of raw shrimp and some clams from the store. It's been eating about every other day lately won't take food daily. It still only comes out at night and early morning. I'm a tank builder so as it gets bigger I will build it a new tank so no worries there.
If you can, get whole bait shrimp,with shell and the head. They love frozen blue crabs. The seem to like the color yellow, so I use yellow objects(like big yellow lego block) to use for target training. For one animal I would suggest at least 100 gallon tank, with a large sump. The more overall system volume the better. Let me know if you have any system design questions. Best way to contact me (firstname.lastname@example.org) Have a good one
Nice to see you around Brian. No fair on the 600 gallon tank! I had asked about the volume of that tank (assuming it is the one that housed the pair several years ago) but never got an answer. LittleBit was TINY for a vulgaris and I never had to move her to the 140. She did not grow at the rate one would expect for vulgaris when she was young (hence my confusion about her species) but she was always willing to eat daily.
Snapped off a small piece of dungeoness crab leg I had in the freezer, it was passed by for the silverside.
Yes it is the same display tank that we had 2 bimac's at one point. It was before my time here at Mote. The system has a 600 gallon display tank, a 80 gallon sump, and a 90 gallon back-up tank with an other O.vulgaris. Life support is a Fluidized bed filter, Jacuzzi mechanical filter, descent down draft protein skimmer, heat exchanger(both heat and chill),and a over sized carbon canister. I personally like to run a lot of carbon with all my cephs. There is a smaller brown Octopus that I have seen around here sometimes, that is bigger than O.joubini, but smaller and less aggressive then O.vulgaris. Have not been able to nail down what species, but I have a couple of guesses.
