Snake Texas
Zoonosis Control Division
The second type of venomous snake found in Texas is the coral snake. Coral snakes are members of a group of snakes called Elapids that are characterized by having a short, permanently erect fang located along each side of the upper-jaw. However, the coral snake does not have to "chew" its victim to inflict a painfully venomous bite. The Texas Coral Snake is the only member of the Elapids that is found in Texas and can easily be identified by the red, yellow and black color bands along the snake's body. The Texas Coral Snake is the only snake in Texas with touching red and yellow bands. ... [Read More]

Invasions of the Brown Tree Snake
The islands adjacent to Guam are the northern Marianas, which have vertebrate faunas that are similar to Guam's, including some of the same introduced species. Like Guam, the northern Marianas have no native snakes. Thus, prey bases similar to those on Guam and capable of supporting high population levels of brown tree snakes exist in the northern Marianas, and species losses can be anticipated if the snake becomes established. For example, of 27 native resident bird species on the main islands of the northern Marianas (Saipan, Tinian, and Rota), 20 are shared with the original fauna of Guam and an additional 7 species are closely related to birds known from Guam. Guam and the northern Marianas also share five introduced bird species ( Engbring et al. 1986 ). Six species of birds are federally listed as endangered or threatened in the northern Marianas, and all of these are conspecific (of or relating to the same species) or closely related to birds that have disappeared from Guam or d ...

ANS Task Force's Brown Tree Snake Control Plan
1. Guam - Since the post World War II introduction of the brown treesnake to Guam, the snake has attained unusually high population levels (perhapsas much as ten times higher (G. Rodda, pers. com.) compared with its nativerange of Papua New Guinea and the Northern Australian Coast. The high densitiesof snakes on Guam may partly be a result of an abundant and diverse prey baseespecially suited for high survivorship and growth of juvenile snakes, and theapparent absence of predators and diseases to the snake on Guam. As a result ofhigh population densities of snakes, there have been frequent human encounterswith snakes resulting in bites and hospitalization of children (at least 50 peryear or 1 in 1,200 emergency room visits are a result of snake bites) (Fritts et al 1990; Fritts et al 1994b). Many other problems have costmillions of dollars, including frequent power outages (Fritts et al 1987)and loss of domesticated animals (Fritts and McCoid 1991). As a result of thesn ... [Read More]

Brown Tree Snake
The first line of defense in keeping the brown tree snake out ofHawai`i involves the U.S. Department of Agriculture's program on Guamto keep the snakes out of the transportation network. This involvestrapping and night searches to remove snakes from port facilities,inspection of outbound cargo and vehicles with snake-detectiondogs, and research into new ways to lower snake population levels on Guam.Searches of inbound planes and cargo are conducted by Hawai`iDepartment of Agriculture (photo at left) as an additional guaranteeagainst snakes arriving into the islands. This is the second line ofdefense. As a final measure, DLNR has trained staff and groups ofvolunteers from other agencies in appropriate methods of findingbrown tree snakes in the field. In the event of a likely brown treesnake report, these teams are called into action to search for thesnake in an effort to ensure that any brown tree snakes that doarrive here do not have a chance to establish a self-sustainingpopulation.

Ground Snake
The Ground Snake is a small(8-18 inches long) crossbanded, striped or plain colored snakewith a head that is only slightly larger than its neck. 1 The top of the snake may be brown, reddish, orange or gray. Thesides are lighter than the top and the bottom is whitish or yellowish.The dorsal pattern in this species varies greatly: 1) dark crossbandsmay encircle the body, form saddles on the top or be reduced toa single band around the neck; 2) dark crossbands may be entirelyabsent; 3) some populations (along the lower Colorado River) havebroad beige, red or orange stripes and gray or bluish gray sides. 1 ...
