How does a stingray sting stuff?

if you play with fire, you're gonna get burnt...THe larger the ray the more likely you will get hit from the sides. The smaller the ray the more flexible it is and anything goes.
I am talking about freshwater rays.
It is safe to assume that wherever the disk is, the tail can reach. Additional point: The spine is attached to a small erector muscle that literally moves the spine independent of the tail giving the spine additional coverage area when it defends itself.
Be curious, be careful. -FM

i just plan on using tongs for everything that requires me reaching into the tank, wont hurt them to sting plastic, would hurt me alot more tho :/
things I found:
When a stingray attacks, it needs to be facing its victim, because all it does is flip its long tail upward over its body so it strikes whatever is in front of it. The ray doesn't have direct control over the sting mechanism, only over the tail. In most cases, when the sting enters a person's body, the pressure causes the protective sheath to tear. When the sheath tears, the sharp, serrated edges of the spine sink in and venom flows into the wound.
­A stingray's venom is not necessarily fatal, but it hurts a lot. It's composed of the enzymes 5-nucleotidase and phosphodiesterase and the neurotransmitter serotonin. Serotonin causes smooth muscle to severely contract, and it is this component that makes the venom so painful. The enzymes cause tissue and cell death. If the venom is introduced into an area like the ankle, it can usually be treated. Heat breaks down stingray venom and limits the amount of damage it can do. If not treated quickly enough, amputation might be necessary. But if the venom enters the abdomen or chest cavity, the resulting tissue death can be fatal because of the major organs located in the vicinity. If the spike enters the heart, as is reported to be the case in Steve Irwin's accident, the results are typically fatal.
While a stingray's venom can do serious damage, the most destructive part of the sting mechanism can actually be the barbs on the spine. The sharp tip of the sting enters a person pretty smoothly, but its exit is roughly equivalent to backing up over those "severe tire damage" blades. Remember that the points of the barbs are facing the stingray. Even if venom weren't involved at all, pulling the spike out of a human's chest or abdomen could be enough to cause death from the massive tearing of tissue that results.
