Hello all,

Dwhatley just created a thread asking for information from those of you who have experienced octopus bites.

I'm going to combine hers with one I've been working on to gather information from all of you on this subject. We can bring together a lot of personal information on bites we've experienced - I don't think you'll find this anywhere else.

Please respond if you've ever been bitten, and if you've been bitten by more than one species, please give information for each.

This is what we need to know:
Species of octopus(if known)
Age of octopus:
Size of mantle:
Type of bite:
(nibble, series of bites, whether skin broken)
How did it occur? during feeding, letting octo climb on top of hand, etc.
Reaction: bleeding, redness, other visible effects, pain, and how long did this reaction last
Comments about the bite and your reaction:
Photos
: Please post if you have any photos of the bite

I'll go first. I've never been bitten, but I'll also respond for my husband Bill, who was bitten by Ollie. You can copy this and modify it with your answers, if you like.

Species of octopus: Bimac (Ollie)
Age of octopus: 6 months
Size of mantle: 3 inches
Type of bite: nibble
How did it occur? During tank cleaning, came down on top of hand, bite lasted about a second and then she tried again
Reaction: little red marks, didn't hurt much, like a little pri
Comments about the bite and your reaction: was a "gentle bite", didn't hurt long, mark gone by the next day
Photo attached

Species of octopus: Octopus gibbsi
Age of octopus: unknown - near full-size
Size of mantle: 25cm
Type of bite: nibble
How did it occur? Feeding/playing and during tank cleaning - didn't even notice at the time
Reaction: two small abrasions, apparently numb at first, then slightly stingy later - took the skin off
Comments about the bite and your reaction: very sneaky!

Maddeningly, I cannot find the photo anywhere, even though I saw it recently and am sure I also posted it somewhere on TONMO. I will attach it later if it turns up...

Nancy, the last three links took me to a 404 Error page?
(Note from Nancy - I've now removed all the links because they aren't working.)

The experience was detailed in the first link, but I'll share the basics here, too.

Species of octopus: Bimac (Mr. O)
Age of octopus: 8 months
Size of mantle: 3 inches
Type of bite: Broken skin, no bleeding
How did it occur? Tug of war with a hungry octopus!
Reaction: considerable swelling and dull pain local to the site within minutes, swelling reduced but still present the next day.
Comments about the bite and your reaction: Mr. O took a chomp on my finger and wouldn't let go--the bite/envenomation was quite painful. He had quite a grip on me and I didn't want to injure him by tearing myself away by force. He spit my finger out in favor of a crab that my wife slipped into his arms. I just noticed that I still have a small scar five months later.

Species of octopus: O. Vulgaris
Age of octopus: ??
Size of mantle: 4 to 6 inches
Type of bite: intense locking bite
How did it occur? during collection out of water. The octo was on the deck of the boat. I was trying to pick it up to get it in some water. It wraped its arms around my forearm and locked on to me. It was painful and took some time to get off without hurting the octopus.
Reaction: Broke the skin. Pain did not last that long. No swelling

I'm sorry to pollute this thread with a comment, but that is HILLARIOUS!

I am posting a pre-bite question, if there is another thread for this please by all means move this. Anyway, as some of you know I am setting up my tank now for my first octo. As far as the bite probability: I am allergic to shellfish, specifically the iodine. I am guessing I must be nuts to try octo husbandry?

There's someone else around with that issue, but I can't remember who. If you're deathly allergic to anything (this goes for anyone) I strongly recommend getting your doctor to give you a prescription for an "epi-pen" which you can carry around to give yourself an injection in case of a life-threatening anaphylactic shock reaction. There are also pills that you can carry that will help.

For an octopus specifically, you can usually avoid getting bitten by not playing quite so aggressively as the folks who have reported bites here; a lot of people interact with octos with a feeding stick or toys, which is similarly fun but less risky for bites. I think there's a post where Neogonodactylus describes the protocol he uses in his lab to make sure that risks are minimized around the blue rings he works with for research, but I can't seem to find it...

Species of octopus: Mercatoris (dwarf)
Age of octopus: 5 months
Size of mantle: 3/4 inch (2 cm)
Type of bite: aggressive
How did it occur? Attempting to teach gentle contact and to associate my finger with a full belly. I have been offering my finger to be touched after feeding in hopes that when the babies are released to the tank they will come out for food when they see my finger but not mistake my finger for food.
Reaction: numbness and slight burning on finger pad to the first joint. No skin breakage (I don't think they can, at least at this age)
Comments: I have been experimenting with this for about a week (not everyday). Three of the 5 have reacted to my finger by grabbing it and sucking for all they are worth. After a few second, two of them simply let go. One of these two will now gently reach out and touch my finger once, sometimes twice but have no more contact (this was similar to the behavior of its mother while brooding).

The one I played with tonight reacted more agressively. It grabbed and held on for over five minutes, staying in its shell and pulling it up into the water column. Initially I could feel it sucking (sort of a pulsing) and trying to bite (I think I felt the beak but not as something sharp, just as a hole). When it could not break the skin, it moved along my finger tip to the nail and tried again there and between the nail and the finger (I think this one is ready for a crab). Once it decided it couldn't eat me, it decided my finger made a good doorway for its shell and discontinued the sucking action and just held on tightly. I tried Dan's wife's trick (unknown to me at the time) of trying to give it other food but eventually, I had to gently disengage it with my thumb.

I can't see or feel any bite marks but the finger tip is warm and has a slight stinging sensation throughout the first joint. I noticed this effect with one of the other ones but the feeling has lasted longer and is more noticable.

I think Jean might have some seafood allergies?

Nope......close though I'm REALLY allergic to peanuts. I carry an adrenalin kit. Peanuts don't have to bite me though :biggrin2:

Species of octopus: Octopus warringa/huttoni complex
Age of octopus: unknown (wild caught) but adult
Size of mantle: 5cm
Type of bite: aggressive
How did it occur? cleaning tank, picked up shell den, unaware that octopus had been put into the tank.

Comments: broke skin, numbness, tingling fingers, loss of fine motor control to fingers, some nuerogenic pain, lasted ~ 3 weeks.

Initial: blue/red in face due to holding back expletives so as not to upset the family who were watching me "play with the octopus"

Lasting effects: ALL staff now remember to record on the tank stock records when they introduce a new animal to the tank.......I :grad: at some length!!!
