The Jumping Viper, or Jumping Tommygoff as it is called in Belize, is a master of disguise. The reach a maximum of about one meter.
Adults are cryptic with diamond-shaped blotches dorsally. According to Bill Lamar, juvenile females are often yellowish to pale gray overall, while juvenile males tend to be red, which later becomes deep cordovan to black in color. The lowest juvenile above reminded us of a juvenile cottonmouth, both in coloration and behavior.
