Southwestern Blackhead Snake
Body length: 5 1/2 - 15"
Although they do come to the surface sometimes at night, blackhead snakes are fossorial, meaning they spend much of their time underground. Little is known about fossorial snakes, for the obvious reason that it is difficult to find them, let alone study their habits. Like other small fossorial snakes, such as ground snakes and blind snakes, blackhead snakes feed on arthropods such as beetle larvae, caterpillars, centipedes, and millipedes. They most often lay a single elongated egg, about an inch long, in late spring to early summer. Though rarely seen, blackhead snakes apparently occur throughout Tonto National Monument.
Did You Know?
Tonto National Monument is home to a crested saguaro. Biologists disagree as to why some saguaros grow in this unusual form. Some speculate that it is a genetic mutation. Others say it is the result of lightning or freeze damage. About one in 150,000 saguaros develop this unusual growth.
