HERP.MX

Non-profit dedicated to researching and conserving Mexican reptiles and amphibians. We find "lost" and new species.

Drug cultivation is a double-edged sword for many of Mexico's mountain-dwelling #reptiles and amphibians. While the practice has inadvertently worked to conserve large swaths of habitat, the accompanying corruption makes it nearly impossible to police illegal mining and logging.

That nursery rhyme can get a fellow killed south of the border (or even north of it, for that matter). This Balsas Coral Snake (#Micrurus laticollaris) is no friend of Jack. In fact, research suggests that antivenom may be ineffective against this elapid's unique venom.

This Sonoran Mountain #Kingsnake (#Lampropeltis knoblochi) was photographed last week in the mountains of Chihuahua. This specimen represents a range extension for the species and a small step forward in resolving the Sierra Madre Occidental kingsnake puzzle.

On the way back from this last trip down south, the field team stopped in for a quick search for these beautiful Dragoncitos or Arboreal Alligator #Lizards (#Abronia graminea) #RealLifeDragons

The target of our latest expedition? This undescribed Evergreen Forest Stream Treefrog (Quilticohyla sp.)

Víctor H. Jiménez-Arcos and collaborators have discovered a new species of treefrog in Oaxaca, Mexico: Charadrahyla sakbah. The species' name is derived from the Mixteco word “sa’bah” meaning “frog”.

Mexico is home to all of the recognized forms of the beautiful Ridge-Nosed #Rattlesnake (#Crotalus willardi). All five subspecies are shown here: C. w. amabilis (TL), C. w. obscurus (TR), C. w. willardi (C), C. w. meridionalis (BL), C. w. silus (BR).

Research by Christopher Blair, Rob Bryson (@phylobiogeo), Charles Linkem, David Lazcano, John Klicka (@odlaasil), and John E. McCormack reveals cryptic rattlesnake diversity in the Mexican highlands. The full article is available here: https://t.co/paRlEqTjK1

There are genera in North America that seem to have distinct spikes in (surface?) activity during the fall/winter. Gerrhonotus is one, Drymarchon, Micrurus and Salvadora also come to mind. What are some others?

Mexican #Bothriechis
All four of the country's (currently recognized) species of Palm #Pitvipers are pictured here. How many can you identify?

[HERP.MX @HERPMX]

Though not the only species of #rattlesnake with a tendency to go rattleless, the Santa Catalina Island Rattleless #Rattlesnake (#Crotalus catalinensis) exhibits the highest rate of rattle-loss of any known species.

#TakeALookAtTheNose on the 10th #Cerralvo Island Longnose #Snake (#Rhinocheilus etheridgei) known to science. More on this species at https://t.co/stZ36WveOM

@TetZoo Thanks for the correction!

[HERP.MX @HERPMX]

Not sure it gets much more bizarre than the Five-Toed Mole #Lizard (#Bipes biporus). Which, of course, isn't a lizard at all, but an #amphisbaenian. More on these in our latest trip report: https://t.co/stZ36WveOM

[HERP.MX @HERPMX]

@snakeymama We have! And not just in Baja, but throughout their range in mainland as well.

We took a break from herping to relax...and herp
