The venom is tetradotoxin. No known animal is able to produce it themself. All must accumulate it. I told that and fine. If you touch it or not is your decission. If you survive it or not doesn't affect my life, right?
You are halfway correct. No known animal produces TTX on on their own and at least some do appear to accumulate it through their diet (although the exact mechanism is still not fully understood). However, some animals acquire the toxin via symbiotic bacteria housed within their bodies and/or digestive tracts. These bacteria are not taken in with food, in fact some species have evolved specialized anatomy to house these bacteria.
Google "endogenous TTX production" if you would like to learn more.
The ones we house show no venomous potential at all. They have problems killing their prey and use "traditional methods".
On a side note, it doesn´t matter if the animals accumulate the venom through its food or bacteria symbiosis. In both cases it must transport the poison to the "injecting apparatus".
We believe the very same procedure for Sinornithosaurus, thats a member of the Dromaeosauridae (most famous of them is Velociraptor).
