Genus

Opheodrys (green snakes)  
       
 

This species was formerly classified as Opheodrys vernalis and contained three subspecies. The genus Opheodrys contained only two species. A study of the genus by Oldham and Smith in 1991 found significant categorical differences between the two species that suggest divergent evolution. The author separated this species into its own genus, Liochlorophis. Crother in 2000 rejected the split. An analysis of the available evidence by Walley in 2003 supported the split. The same analysis rejected recognition of the three subspecies. Most print and online sources continue to refer to this species by its former classification, and consider Liochlorophis vernalis a synonym. The use of the genus Liochlorophis, though appropriate, has fallen out of usage.

Frequently Asked Questions:

1- Where do you find all this reptile news?
I work about 7 days a week most weeks scouring the internet for reptile related news. I find hundreds of stories per week from different places all over the world. The unfortunate part is I can only pick a few per day to talk about because of the time it takes to produce the show but I do post a lot on the website that never makes it on the show.

2- Why is your reptile news always doom and gloom?
I love happy news, we all do but the sad fact is our community has a lot of bad news going around right now and I dont make the news, I just tell it so its not really me promoting doom and gloom, its more like just informing you and promoting us as a community to ban together and change the future.

3- Do you actually think you are helping the reptile hobby?
Not only do I think I am but I know I am. I am a huge supporter and promoter of the reptile hobby as well as super pro business. I spend every single day helping to promote a positive image of our hobby to the general public, what have you done to promote our hobby today?

4- Will you promote my site, channel, business exc exc?
Yes I would love to do all of the above but I have a strict new rule that before I allow any promotion on DRN the person must first prove that they are doing something to help our community.

I have been providing the daily reptile news for several years now. I started it with Foot Hill Reptiles in 11/2006. When I sold FHR I started foothillherps.com and continued to provide the news on the forum. In January 2010 I started providing it via you tube as well as the FHH forum. In February 2010 we went to high definition coverage of the important daily news as it pertains to reptiles and amphibians. On March 15th, 2010 dailyreptilenews.com debuted as your #1 source for Daily Reptile News.
