This photo was shared with me, and I got permission to post it here. A melanistic gartersnake from one of the islands off British Columbia, Canada.
The person who took the photo said the snake looked "ominous". It's amusing how folks react to black snakes.
I'm not sure which species are on the islands out there.
Melanistic Garter sp.

Re: Melanistic Garter sp.
Nice one. Looks like an ordinoides.
Re: Melanistic Garter sp.
That's Thamnophis elegans nigrescens, a subspecies no longer recognized, that are now considered very dark Wandering Garters, Thamnophis e. vagrans.

Re: Melanistic Garter sp.
beautiful specimens. I hear that the T. hammondii has a dark morph on Catalina island. I've tried to find it twice, both time taking a whole day to hike the entire watershed with no success yet. These pictures make me want to try all that much harder.
Re: Melanistic Garter sp.
I love melanistic anything. Garters are exquisite.

Re: Melanistic Garter sp.
I dig the black ones from lower Baja. They are handsome little buggers for sure.

Re: Melanistic Garter sp.
OK, I have to ask. How can you tell that it's a garter snake? What are you using as an indicator(s)? I'd be flipping through the pictures in the snake book and scratching my head.

Re: Melanistic Garter sp.
Hmm. really good question actually. In my case with Thamnophis elegans there are only 9 snake species locally, none of which are typically black, small, have keeled scales and smell like a gartersnake. This one also acted like a gartersnake, so gestalt I guess.How can you tell that it's a garter snake?
Sorry I don't have a good answer for you. There are certainly characteristics that would key out to gartersnake. I can look them up for you if you want?

Re: Melanistic Garter sp.
Garter snakes are the only snakes in the northwest that are known for melanistic specimens like that. You can also see faint dorsal and lateral stripes on it. Though, I have seen a few elegans that have no trace of stripes at all, just pure black, or black with two white spots on the head.
It still looks like ordinoides to me due to the thin largely straight dorsal stripe, and they are a species known for having melanistic specimens. They are also usually much more common than elegans west of the Cascades. But cannot tell decisively without a closer photo of the head.

Re: Melanistic Garter sp.
My assignment to T. elegans was initially based on the intrusion of the dorsolateral dark blotches onto the vertebral stripe seen on the neck. That characteristic is typical of T. e. vagrans vs. T. ordinoides. Also, enlarging the photo shows 11 scale rows from lowermost scale row to vertebral stripe at the middle of the body, which translates to 21 midbody scale rows. In addition, it has 8 supralabials. All of that means is it is a melanistic Wandering Garter Snake, Thamnophis elegans.

Re: Melanistic Garter sp.
There are definitely morphological characteristics that would indicate a garter snake, but mostly it's just that we've all seen enough garters/pictures of garters to recognize them on sight. I know it's not very helpful at all, but with practice, I'm sure you'll be at the same point soon.BethH wrote:OK, I have to ask. How can you tell that it's a garter snake?

Re: Melanistic Garter sp.
Thanks for all the answers! I do hope I get better at identifying snakes. I'll be moving to a new area soon, and there will be a whole batch of new animals, plants and birds for me to learn. Beth
