With the end of the successful 2024 reboot, a new year entails, so to you I present the ZooChat Challenge Great Britain, Ireland & Crown Dependencies 2025: Slithering Serpents

With inspiration taken from 2025 being the year of the snake in the Chinese Zodiac, if you hadn’t already guessed, your challenge this year is to see as many species of snake as you can.

I thought I’d keep the task simple again like last year, before some more diverse challenges planned for the next two years. There are a huge number of snake species spread throughout Britain & Ireland, however very few collections hold large numbers of species. As such, the challenge this year should be quite close and hopefully keep churning right the way through the year.

Of course, the same usual rules courtesy of Shorts apply:
1. You have to actually see the animal, even if just for a second.
2. Photographic proof is not required, your word is your bond.
3. You must see the animal from normal public access areas and during normal public opening hours (no special experiences)
4. Only species seen at a zoo in the geographic limits of the challenge can count in this challenge.
5. However, any private zoos or zoos with limited opening dates don’t count.
6. Record your tallies on this thread after each visit.
7. Whilst not compulsory, I would recommend including scientific names in your tally.
8. The winner will be the individual who has seen the most species of snake by midnight 31st December 2025!

So any species in the suborder Serpentes will count and colour morphs (but not hybrids) are allowed. I’ll add extra emphasis on the species level. No subspecies, and try to use the IUCN classifications if unsure on current species splits. As always, taxonomy is never simple, and so some species are unclear. Any questions, just ask, and I or someone else will try to answer.

In short, you have exactly 12 months to see as many snake species as you can. So without further ado, let the challenge commence!!!
 
I make it a total of 76 species in public collections, of which only about two-thirds are onshow.

I'm guessing that is according to ZTL,inwhich case the number will actually be about 100 species so people still could achieve the maximum of your total, and also a number of places have their snakes wrongly labelled so can what they are labelled as be counted or is it the correct species that is counted?

In answer to your question... hopefully that situation won't occur too often. If you see a mislabeled species and can work out what it actually is then that is great and you can count the correct species for the challenge! If unsure however, then there is nothing wrong with putting a photo in the thread to ask for some ID'ing advice!

I won't be taking part in the challenge, but I admire your optimism that it won't happen often,it will happen and anyone counting carpet python for Linton zoo will be wrong unless they count it as a bredls python and that situation has been in place for over ten years.

I've started my list.

I'm not 100% sure on the last one. I did see a snake (it's the third one from the left as you enter the reptile house from the path leading from the reindeer), but there was no information sign. I picked the one that most closely resembled what is listed on ZTL, but if anyone knows better, please let me know.
