Here are two interesting venomous snakes I found in a herpetologically unexplored part of Colombia back in 2011 on a Cartel cocaine smuggling route #TBT Bothriechis supraciliaris (Taylor, 1954).🐍 No good pic's of the blue one, but you can imagine.

Nerds! PSA FYI🐸the reason poison arrow frogs was used for these frogs firstly is cause "arrows" were also considered darts when discovered in 1841; the language then considered arrow=darts. Poison Dart Frog presumes the frogs have darts; untrue. Hence, Dart Poison Frog is the correct vernacular.

I do #transtrips. I take non-binary; often autistic/disabled people outside herping. Here is my nephew/niece Mave in what I'd call a state of adoration upon finding & interacting w/ their first L. t. triangulum (Lacépéde, 1789). 29th April 26 my buddy Chuck & I found him again four-yrs. later, same🐍

Happy #snakesaturday! Some Red Ratsnakes, Pantherophis guttatus (Linnaeus, 1766). Rare and/or state endangered in their northernmost range; MD, DEL and NJ. If you know where to look and when to look they can still be found. It's their mating season up here.🐍 Many get run over by cars😔💔

14 celsius & overcast... My buddy Chuck had his doubts. One new milksnake at Den No.1 & a recapture at Den No.2 after 4-yrs. Not a bad way to start the morning. Enjoy!🐍

Many snakes from the very-high-elevation equatorial Andes to the high-latitude of Canada are cold wet tolerant & active in those conditions. Here is proof; ~9 degree Celsius at ~2400 meters elevation. I give you Cata in Colombia & an Erythrolamprus. Amazing, perhaps unexpected huh? Pic by me🐍

#toadtuesday. Not sure of their current nomenclature. They were from my time spent in the Brazilian Atlantic fragmented forests "Mata Atlântica, Brasil". Very large & very cool toads. Big shout out to Conservation International for funding my work there & all the friends I met & made there💚🐸

0133

#timberrattlesnaktuesday. "Mouse". A nearly 5-foot "Gold" Timber Rattlesnake, Crotalus horridus Linnaeus, 1758 that visits our compound in Shenandoah Co. VA in GWNF inholding. He's never bothered anyone in decades; he just spends a month each year under some of our buildings eating mice. He's good.🐍

Lauren, Moi & Ika Enomenga and me, all Huaorani Ecuadorian Indians. Just sayin' you had to have been there.

10-yrs. ago I suggested to Steve, John & his wife and James and a few trusted others "let's go find the ultra-rare 'Day-glow' magenta mole king snake". A site now cleaned-up-no more AC study transect. W/O AC and if you are very skilled you might have a few days in a year to find them on the crawl.🐍

Lampropeltis rhombomaculata. Pic credit J. Lee (but I found the snake & showed him the site). The habitat is now a Royal Farms gas station parking lot. I moved 2-pairs, females gravid to a nearby safe place that won't be developed w/ MD-DNR permission. Makes me want to listen to Rush "subdivisions"🐍

0101

Kevin Enge discovered this so-called "Mosaic Eastern Kingsnake" Lampropeltis g. getula (Linnaeus, 1766) on an island off Georgia, USA (in the 1980's). A few years ago (2022?) a friend found & took this pic on the mainland 11 walking miles from any paved rd. in North Carolina of a "Mosaic" king.🐍

🐍A friends basement foundation where all snakes (all, but these are just black ratsnakes) and are others welcome inside & outside of "The Beltway" for decades in his home. Generations of friendly snakes. Don't drain "The Swamp".🐍

Evidenced. The Scarlet King Snake (Lampropeltis elapsoides (Holbrook, 1838) occurs in MD and sporadically northward in rare habitat dependent isolation. Kahn T. & Andrews B. in accepted manuscript.

Happy #milksnakemonday! Eggs & two polymorphic Eastern milksnakes (Lacépède, 1789) were found <5 meters apart, November 2017 (apparently each from double egg clutches). Each is from different genetically related parents. Why such atypical variation? Welp, working on the publication. Pics by me.🐍

Ted R. Kahn @tedrkahn.bsky.social · 27/04/2026

Happy #milksnakemonday! These two polymorphic Eastern milksnakes (Lacépède, 1789) were found under the same rock a few days apart in early June of 2011 circa Washington, DC in a parking lot. Pics by me. Don't drain "The Swamp"!🐍

Missed #snakesaturday so #snakesunday! Enjoy a Washington, DC native, Den#1; it's going to be a long & productive Spring season methinks. Northern Copperhead (venomous), yet generally inofensive in daylight, at night, not so much & may be fussy. Also a scansorial🐍; a fancy word for semi-arboreal.

The USA president just committed an international war crime by threatening to destroy civilian infrastructures in Iran. There is no statute of limitation. Arrest him now and any service members who follow his war crime orders. End of story.

#notfrogfridy but have some free large poison frogs anyhow; Oophaga sylvatica from Colombia w/ scale from smallest to gigantic! Graphics and paintings by me as usual🐸
