Gopher, Pine, and Bull Snakes-The Genus Pituophis

By Patrick Houston Briggs

The genus Pituophis pronounced "pit-chew-oh-fis" is a collection of contrictors with similar characteristics classified within the ophidian family Colubridae. They are gopher snakes, pine snakes, and bull snakes. The scientific name comes from the Latin word pituitarius referring to phlegm  or mucus. It could be associated with the intense hissing produced by these snakes. Interestingly, Pitys is also Greek for "pine" and Latin for "pine-cone", so it is very appropriate for the the pine snake species. The ophis portion of this scientific name is Greek for snake. Holbrook established the first Pituophis in 1842 upon the northern form of pine snake that is recorded by Daudin as Coluber melanoleucus in 1803. Coluber is Latin for snake. Many of the Colubrids have 2 prefrontal scales, but within the genus Pituophis, with the exception of a few species, there is usually a trademark of 4 prefrontals, at least on most individuals. Others may vary a little within a species, with some individuals deviating from the rule, having only 2 or others having azygous or intermediate scales between the prefontal and internasals especially within intergrade zones.

The first image below on the right is the upper head of Pituophis deppei deppei and clearly shows only 2 pre-frontal scales touching the frontal scale ( the center scale beween the eyes). On the right side image, can be seen Pituophis catenifer annectens clearly possessing 4 pre-frontal scales contacting the frontal.

Although there are exceptions, such as a few island forms, these snakes can grow to be robust, powerful, constrictors that prey on lizards, birds and their eggs, as well as rodents, such as gophers, rats, mice, and young rabbits. Generally they are clad in light ground coloration with dark blotches and spots, but individuals have been found in nearly all the different races that also have the striped pattern morph. Color and pattern variation is extreme, both at the specific and subspecific levels of Pituophis. Some, such as Pituophis vertebralis are split up as pattern classes by some authorities, while others give them subspecies status. Furthermore, a few, such as Pituophis melanoleucus lodingi lose their pattern completely as they mature, and become completely "melanistic" or black as adults. Many Pituophis also have darker markings toward the rear and front of their bodies while they are much lighter at the mid-body which makes them appear as two different kinds of snakes.

Temperment of different Pituophis can vary just as much from one individual to another as it can from one species or race to another one. I've always been impressed at the tenacity of some of these reptiles that have been cornered or feel threatened in the wild. Indeed, if they are agitated, muscular coils are deliberately flexed and relaxed and the head is boldly raised and flattened as the tongue extends and slowly rises and lowers, the bifurcated tip droops downward. At the same time an intense hissing is produced as inhaling and exhaling of air passes by a cartilaginous membrane flap or preglottal keel jutting upward at the front of the glottis, an opening at the floor of the mouth below the base of the tongue. Furthermore, as the pivoting head follows the movements of the intruder, the tail rapidly vibrates with a determination to intimidate an intruder. All of these instinctive behaviors and tools working in conjunction with one another become part of a bluffing strategy and effective mechanism to fool any menacing preditor into believing its potential prey is an irrascible creature or a scaly devil far too dangerous to manage. If that isn't enough, repeated strikes towards the intruder should hasten a decision for it to retreat and search out other prey. This allows the magnificent ophidian to finally pacify, and slowly slither away, and having again, survived, to live another day.
