We collect as much information as possible about Asian Lancehead, family Crotalinae, present in Asia. The main purpose of this space is focused on knowledge sharing.

The project

It would be justifiable to start by reminding how many snakes are a public health priority. Trimeresurus albolabris alone accounts for 40% of envenomation cases per snake in Asia while Viridovipera stejnegeri accounts for almost 70% of cases of bites in Taiwan (Rojnuckarin, P., Chanthawibun, W., Noiphrom, J ., Pakmanee, N., & Intragumtornchai, T. (2006), Cheng, CL, Mao, YC, Liu, PY, Chiang, LC, Liao, SC, & Yang, CC (2017)). It would also be appropriate to start with a brief history of the evolution of viperidae and crotalinae which includes the species of the genus reported in these pages. Although these two approaches are fair and bring a “professional” side to the field, my goal is to democratize, to a lesser extent, the fundamental aspects that can be addressed when we talk about “irons”. Asian spear “.

Having a scientific mind, I can only say so much that nothing is ever really complete or accomplished. It seems important to me, as a research work, to specify the limits of such a site. The first seems to be, obviously, knowledge. I will never pretend to know everything regardless of the time spent studying. The second being well understood as it ages, the information becomes obsolete in favor of new study results. For this reason, I hesitated for a long time with the making of a book. The last, and not least, is the democratized aspect of a book. They are, I think, faster subject to misinterpretation and “forgetfulness”, voluntary or not sometimes too scientific term for the greatest number.

Nevertheless, I am and remain convinced that the exchange of information is important, especially when it is scientifically proven. For this reason, each theme is the result of bibliographic research.

I appreciated the ease of use and clarity … It is very informative and I think it should answer the questions of many amateurs and specialists.
