One of the small, fossorial snakes of the southeast – a Midwestern Worm Snake. These tiny guys specialize in earthworms, but may take other soft-bodied invertebrates as well.

Arizona Black Rattlesnake giving me a reminder to keep my distance and leave it alone. I spotted this one crawling from a small drainage back to tangled debris at the base of a sycamore in southern Arizona.

Southwestern Speckled Rattlesnake resting under a bush on a cool Spring day. With temperatures still in the low 50s at night, this snake sat out overnight waiting for prey to wander by, nearly a quarter mile from its den further up the bajada.

Blacktailed Rattlesnake showing off the “desert phase” phenotype, typical of lower, hot desert regions where this snake is common in rocky hills and mountains. This chaotic pattern can range from a yellow-green to silver, at times with the pattern degrading to the point of a unicolor appearance. This one is typical for mountains west of Phoenix.

A large Western Ghats King Cobra resting in foliage at the edge of a field in Karnataka, India.

Sonoran Lyresnake from the eastern end of Arizona. These are secretive snakes that live on rocky hillsides, eating lizards and small mammals. They are mildly venomous, and can cause a reaction in humans, but typically not considered dangerous. Fortunately, a bite can easily be avoided by just leaving these shy animals alone.

Arizona Black Rattlesnake from a desert population. Many of the snakes here are all black, missing the white or yellow scales that are typical in the more often photographed locations. This one has just a hint of yellow in some dorsal scales, but is otherwise all black or grey, including the belly.

A Western Diamondback Rattlesnake on a hot night time survey of a county park. Thermal cameras show snakes selecting the coolest surfaces in the area to rest in and against – there is possibly more to this, which we are looking into.

A Southwestern Speckled Rattlesnake found in the lower foothills of the Cerbat Mountains of Mohave County, Arizona.

Arizona Black Rattlesnake lying in ambush nearly vertically against a boulder near an isolated water hole on a hot summer night.
