It is similar to A. p. portoricensis in having dark-edged scales and in lacking the reticulated dorsum, but there is a moderate to distinct lateral stripe (the particolored scales of the stripe have a rosette of two to four pale scales above), the chin and throat are heavily marked and the head may be plain or variegated. This boa is a viviparous snake, which means it gives birth to live young. A herpetologist friend, who is more resistant to the venom, only develops minimal swelling. The head is variegated with black and usually bears a dark face mask. Upon closer examination, the small fangs are visible, partially covered by gums. Anoles are the cute little lizards you see all over Puerto Rico. After about 30 seconds, the lizard succumbs to the toxic saliva flowing from the snake's rear fangs.

I had an exceptionally large Alsophis that fed regularly on white mice. Its primary color is a dark, shiny mahogany brown, with dusky wavy lines across the back that can only be seen under close observation. It measures 10 inches (260 millimeters) in length, from snout to vent. The color is tannish brown, and many of the scales are edged with dark. The ventral scales may have a faint dark margin, but it is not as dark and conspicuous as in A. p. portoricensis. Rear flanks are yellow with dark edges. Some specimens can be tamed down with frequent interaction from a patient keeper, but I do not recommend Alsophis as handleable pets. Somehow, with its speed and secretiveness, the snake remains abundant in many parts of the island. If it doesn't bite, it will release a foul smelling musk from its cloacal glands. In the wild, snakes also become infected by parasites, external and internal. Sometimes, a slight change in temperature and environment will make the parasites look for another host. As the lizard approaches the base of an acerola tree, a dark, shiny arrow shoots down from one of the low branches and lands squarely on its neck. Allergic persons should avoid the snake altogether. The anole can also change color from brown to a bright green and back again, but so far no one knows why. In captivity (I presume it also happens in the wild), Alsophis will often lift a freshly captured prey lizard off the ground and carry it a few feet from the spot it was caught.

The Racer is the second largest snake in Puerto Rico, but still only grows to about 3 feet (.9 meters) in length. Often, the snake would start swallowing it before it was completely immobilized. that feed on baby lizards often fall victim to the parasites carried by the lizards.

It is the largest of the Alsophis subspecies and the most common snake in some parts of the mainland. They are generally considered non-venomous, although studies have shown that at least one species, the Puerto Rican racer, secrets some venom. *, Researchers Rediscover Malagasy Chameleon After 100 Years, Invasive Lizards Adapting To Florida’s Cold Weather, Three Ball Pythons Abandoned In Pennsylvania Town, 200 Loa Water Frog Tadpoles Born At National Zoo of Chile, Wild Turtles In South Carolina Now Protected From Poaching. “The Puerto Rican Galliwasp is a snake-like, elongated, flattened lizard with tiny limbs, a thick, heavy tail and almost no indentations separating the head, trunk and tail. The anterior part of the body generally shows a dark, reticulated network. A keeper should be aware that it is a slightly venomous snake. It didn't lift the mice off the ground.

The chin, throat and anterior part of the body are heavily marked with dark spots. Housing for this snake should not present any problems. Rats can be dangerous to them, and cats and pigs also kill snakes. Alsophis portoricensis variegatus inhabits Mona Island. Stress makes captive life (and its limitations) worse. They prefer dense clumps of cacti in semi-arid regions, but can also be found around rocks and under coconut palms. The thick-bodied snakes, native to parts of Central and South America, can grow up to 10 feet long, weighing up to 75 pounds; they have no natural predators in Puerto Rico … The snake engulfs its prey in a few minutes. Many species of reptiles are imported, both legally (mainly through the pet industry) and illegally, to the archipelago of Puerto Rico every year, with some of these species being subsequently released into the wild. This is especially important with mice feeders. It grows to about 2 feet in snout-to-vent length. Originally described in 1868, the crested toad is found only in Puerto Rico and the Virgin Islands. As expected, the bite was followed by acute itching, which was soon followed by heavy swelling. According to Dr. Juan A. Rivero (The Amphibians and Reptiles of Puerto Rico, 1978), subtle differences between each subspecies make each one distinctive within its range. It feeds on small mammals, birds and lizards, and since it lives in the karst region of Puerto Rico on the Northwest coast where there are caves, it also feeds on bats. Several months ago, in my backyard in Puerto Rico, I spotted an Alsophis in a tree, about 3 yards away. A fellow hobbyist was very unlucky. Eeek!
