The more reading I do, the more I find out about the suprising defensive mechanisms some of these saltwater aquarium creatures have, such as the thumb splitting mantis shrimp, stinging lion fish, spearing mantis shrimp, and most suprisingly stinging bristle worms? I wonder what other sw critters has these traits to be forwarned of? As a complete newbie I do not want to stick my hand in to grab something to painfully find out that it can defend itself! I was wondering if some of the more experienced members would mind listing off a few of the common sw critters that you do not want to get to friendly with, and what they would do, and how much it would hurt (I am kinda facinated now) because if I had not been browsing through these forum pages, I would have never known to not just grab a bristle worm!
 
You forgot urchins. :D
When I first started I was scared to touch anything. Now I have no fear of reaching in and doing what I need to. That's not to say I shouldn't have any reservations. I've just been lucky thus far. :roll:
 
urchins sting too? 8O I hope to one day have a tank full of dangerous sea creatures, makes an interesting conversation point for sure. There must be alot of people on here that have had a run in with an aquarium creature, I wanna hear about em!
 
Stonefish and scorpionfish are venomous as well. Those two are very nasty.

I've had close calls with Lions, and Scorpions but so far I've been lucky. When I worked at Petco I had a co-worker stung by a lion, but he was fine. He was envenomated, but heat was added immediately so he was fine.
 
So far there hasn't been a case of a lionfish killing someone so you should be fine lol. Most likely he got stung by a dwarf lion, nothing but a minor throbbing pain after a while.

Urchins don't sting, but they're spines poke you.

There are many things that can hurt you, not kill but hurt. Some things of course like blue ringed octopuses though can kill you.
 
As a general caution to all on this topic, lets be careful about what is presented as fact if you don't have factual experience or proof. Also, while most things aren't deadly themselves, there is always a risk that you may have a "reaction" to somethings defensive mechanisims.

Urchin spines CAN have venom in them. This one I speak from experience. I had a long spined urchin and was moving some rocks around and he got curious and moved a lot faster than I thought he could! I got jabbed in the back of the hand. A thick black substace was under my skin and a strong burning sensation was present for a few days. Urchin venom is often not enough to put you in danger by themselves, but you CAN be in trouble if you have an allergic reaction. When my hand started burning I got nervous but didn't feel any other effects and I was stabbed once more by the same critter with the same sticky venom and burning. It left a black spot on my hand for about a week or so.

The reaction danger holds true for ANY creature that has a sting or venom. A bee's sting, for example IS a type of venom. It's just not toxic enough to kill the average person, however we all know that someone who's allergic can have deadly problems from even a single sting.

Another critter to be cautious of is the spiney puffer. Similar to a bee sting IIRC (in terms of toxicity).

A number of anenome's and corals can also have a sting that you could be affected by.... for some reason hammer Coral comes to mind, can anyone back that one up or refute it for me?
 
Some blennys also can inflict a painful bite. Canary, vampire, and a few others. They won't attack your hand, but be careful not to handle when netting.
 
ill second that zooanthid thing....i work at a really good LFS and one guy didnt know and just put a whole bunch in a tank barehanded and then went out to have a cigarette and rubbed his eye....lets just say he had to go home for the day
 
The only critters that you really don't want are mantis shrimp, very large bristleworms, and there are some worms that are bad if you are keeping clams. Also large hermit crabs and predatory crabs can be a problem sometimes. There are also some parasitic amphipods although rare.


I do however plan on having a mantis tank sometime soon. If I can find a pretty spearer type I might go with one of those, otherwise I think I might get a peacock smasher. :twisted:
 
Sorry about that lol.

You'll certainly have a different reaction to a lionfish if your allergic to bees. Most people will not though. The most damage i've heard of someone getting is having they're thumb swell up and hurt for a couple wekks.

And I never knew urchins had some venom in them lol. I was always told they just poke you lol.

Yep, all Euphyllia species have a strong enough poison in their nematocysts that after many (30+ estimated) exposures to it you start to put yourself at risk for an anaphylactic episode. This is not limited to Euphyllia but also Millepora, Cataphyllia, etc. as well as most anemones.

One other note, to be specific, bristle worms don't "sting" as say the firing nematocysts of corals/anemones do but rather them stinkin bristles break off under your skin and can cause a burning reaction. I pulled a piece of rock out of a bucket that I thought would have no hitch-hikers and got a finger full where it looked like a toothbrush. Elbow length gloves these days. :wink:
