Dear Venomland Members and Friends, Venomland is a little more than 6 years old now and by far the biggest Hot Snake community on the Planet! We want to thank all of you who made Venomland the leading Board. We are also very thankful to our Moderators and Admins for years of hard work. Now, it is time to move on. I have been thinking how to proceed and what to do with our beloved board as we reach a size, that we need to make drastic changes to secure the future of our community. As of now, Venomland is hosted by a free (well mostly free) hosting service. That was good for the first years but now we need to find a new way to run our forum. I have spend hundreds of Dollars over the years to keep Venomland up and running, and i have done so with pleasure. Now, we need your help! We need to come up with several thousand dollars for our Venomland 2.0 project, which i frankly cant pay for any longer by myself. So Venomland is asking his Friends and Members for the first time for their financial Support. Please help to keep Venomland alive, and let us move on to a new, better Portal in the Future! Every Dollar is helping us a great deal. I know, its hard times for everyone, but please spare a few Dollar for our community. If you have only 10 Dollars to spare, we are grateful, if it is more, it would be awesome. We are planning to develop a very new Venomland, with real community functions, a forum like you are already loving it and a real (online) Hot Snake Magazin. Also, there will be download areas for scientific papers, Wallpapers and more. Again folks, we can only do that if you all help. Please send me a Private Message if you want to keep Venomland alive, i will provide you with the details on how to donate Money. For now, we can accept money from creditcards via skrill (please google it, its a free service - account-details will be forwarded to you) and paypal. All the best, and for a (hopefully) nice future of our Board. Mario

Show me the white tail, then I believe in your found Wink
congrats, we were searching around La Gamba and La Palma without finding one...
Would you share some more details about the location and the habitat where this specimen has been found ?

Thank You

Gregor,

I didn't disturb the snake when I took the pics, so I have no pictures of the tail. It was coiled along a trail. This snake was near La Palma, but further up the Rio Rincon in the mountains and not far from the new Los Patos ranger station.

To my knowledge, all of the Porthidium on the Osa Peninsula are considered "porrasi", but really all that means is that they are an isolated form of Porthidium nasutum ( or Porthidium lansbergi.)
