description
The Sinaloa triangular snake is a powerful snake. It reaches a total length of 90 to 122 centimeters and is rarely larger. The basic color of the body is red, on which there are black bands at large intervals, which are separated into two by a white to ocher band. The distance between the bands may decrease towards the tail. In the neck, a black band forms a triangle, and the corresponding side of the white band takes the shape of a funnel. The top of the head is black and the large, wide scales on the belly side are light in color and stained black and piebald. The Sinaloa triangular snake can reach a maximum age of over 20 years. It is active at night and at twilight and predominantly lives on the ground, but occasionally seeks out low bushes.
Reproduction
The Sinaloa triangular snake hibernates over the cool winter months. With the rise in temperatures in spring, the breeding season begins. After successfully mating two animals, it takes about eight weeks for the female to lay a clutch, between two and 17 eggs. The hatching takes place differently depending on the temperature, at 28 degrees Celsius after 56 to 64 days. When hatching, the young measure 23 to 25 centimeters.
distribution
The Sinaloa triangular snake is common in Mexico . It occurs in western Mexico from southwestern Sonora to Chihuahua . It is named after its occurrence in Sinaloa . It lives in the coastal lowlands and penetrates at heights of up to 1,000 meters. Settled habitats include dry to moderately humid areas, especially agricultural areas such as grain fields and deserts. During the day she hangs under cacti, bushes, in huts and barns, under boards, metal sheets or similar hiding places.
nutrition
The Sinaloa triangular snake eats small mammals such as rats and mice , which they also lure to the grain fields and cattle sheds, birds , eggs and small reptiles such as lizards and other snakes .
