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. Stress makes captive life (and its limitations) worse. Because it is somewhat difficult to distinguish it’s head from it’s tail it is sometimes referred to as a “two-headed snake” (in Puerto Rico “Culebra de dos cabezas”) by local people. But they are free to move from one place to another, to change their diet and to make conditions unfavorable for parasites. The color is tannish brown, and many of the scales are edged with dark. When preparing to strike, it raises and spreads a cobra-like hood (narrower than that of a cobra). The Sphaerodactylus klauber is also known as Klauber’s Dwarf Gecko, named for American herpetologist Laurence Monroe Klauber.

Like all babies, they are highly vulnerable at this stage; a common toad might confuse one for an earthworm and get away with eating it! According to folklore, wearing a live [worm lizard] on your body ‘helps safeguard pregnancy’ while wearing a dead snake ‘helps rherumatism’.” Worm lizards can be found under logs and rocks. On this occasion, the rear fangs were embedded in the little finger of my left hand. Sometimes, a slight change in temperature and environment will make the parasites look for another host. Several months ago, in my backyard in Puerto Rico, I spotted an Alsophis in a tree, about 3 yards away. The top screen should be sturdy and provide ample ventilation. As for the reptile, it only bites when cornered, molested or grabbed. A stress-free animal lives a healthy life, feeds well and even breeds for several generations. I have observed that baby rat snakes (Elaphe spp.)

Exceptionally large specimens are fast and powerful. Skinks eat invertebrates and plants. 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. 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. A fellow hobbyist was very unlucky. Often, the snake would start swallowing it before it was completely immobilized. It is a prolific genus with over 391 worldwide, and there are 9 varieties on the island. Rear flanks are yellow with dark edges.

The Puerto Rican racer's reproductive behavior remains largely unknown. When a juvenile Alsophis survives, it makes a superb lizard hunter.

The following descriptions are the most reliable in his study: Alsophis portoricensis portoricensis is chocolate brown, and each scale is edged with dark brown (or white on the anterior part of the body). It didn't lift the mice off the ground. The head has no markings, and the throat is either white or marked with diffuse blotches. It was painful. 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. Alsophis portoricensis aphantus is found only on Vieques Island. A herpetologist friend, who is more resistant to the venom, only develops minimal swelling.

This is a list of the reptiles of the archipelago of Puerto Rico.The Puerto Rican archipelago consists of the main island of Puerto Rico, two island municipalities, Vieques and Culebra, one minor uninhabited island, Mona and several smaller islands and cays. Their pupils are round and clear. Once finished, it slowly climbs back up, silently disappearing from the sight of unsuspecting victims. If interrupted in the process, the snake might let go of its prey. I had an exceptionally large Alsophis that fed regularly on white mice. The snake engulfs its prey in a few minutes. The Puerto Rican Racer is the only venomous snake on the island, but it is only mildly so. Also known as the Common Blind Snake, the worm lizard can be found in El Yunque. The chin, throat and anterior part of the body are heavily marked with dark spots.

Originally described in 1868, the crested toad is found only in Puerto Rico and the Virgin Islands. This is a list of the reptiles of the archipelago of Puerto Rico. Alsophis, like all racers, have extremely long tails. Soft, scratch-resistant screen tops are a great choice, though I have yet to see an Alsophis grate its nose on any surface. Hatchlings are about 8 inches long and feed on baby lizards and frogs. The head of the Puerto Rican racer is pointed at the snout but is thick at the upper jaw to accommodate the venom glands and the rear-fang apparatus. Conversely, when hunting or stalking, they are capable of the slowest movements, whether slithering on the ground or resting on the branches of a tree. Unlike the wild-caught lizards that can be fed to an Alsophis, the mice fed to my snake were raised at home. Galliwasps can measure up to 5 inches (125 mms) SVL, but the ones in Puerto Rico are usually much smaller. The ventral scales may have a faint dark margin, but it is not as dark and conspicuous as in A. p. portoricensis. Its primary color is a dark, shiny mahogany brown, with dusky wavy lines across the back that can only be seen under close observation. Alsophis have several predators, but they are still common in many areas of Puerto Rico.

Then it swallows its kill. Upon closer examination, the small fangs are visible, partially covered by gums. They also need a large water bowl.

This boa is a viviparous snake, which means it gives birth to live young. It thrashes about, but the snake hangs on, like a high voltage wire. Alsophis portoricensis richardi ranges from Culebra Island to most of the Virgin Islands. The snake will then crawl away swiftly, as though it were showing off its grand prize, at the same time keeping the prey away from the jaws of another predator, avoiding the possibility of being robbed of its meal. Besides man, the mongoose, the red-tailed hawk and the Caribbean sparrow hawk are its worst enemies in the wild. Also known as the yellow tree boa, this non-venomous snake is brown in color and can grow 6-8 feet (2-3 meters) long.

They are insectivores whose SVL is about 6 inches (15.2 cm). The rough, scaly skin of the lizard offers little resistance to the snake's jaws. Habitat loss has resulted in a decline in population and it being placed on the list of threatened species by the US Fish and Wildlife Service in 1987. that feed on baby lizards often fall victim to the parasites carried by the lizards. Basking in the sun, it remained perfectly still even as I passed beneath the tree. It is found in El Yunque where it dines on coquí and anole. I have been bitten several times by this snake, but only once did it get a firm hold on my finger. Alsophis are fast racers, making their capture rather difficult. He was bitten on his forearm and had to be taken to the hospital because the entire left side of his body was paralyzed. However, although cobras spread their hoods readily, Alsophis needs to be provoked. Alsophis portoricensis prymnus is found in southern Puerto Rico; it is also fairly common in Caja de Muertos (a small island off the south coast). It also has a reticulated dorsum, especially prominent on the anterior part of the body. To minimize stress, do not disturb a nervous snake and supply it with a hiding spot in its cage for security. A healthy Alsophis living in a quiet place will thrive on one lizard a week. It will return later to get it after curious onlookers go away. He was given anti-inflammatories to reduce the swelling.

The substrate can be newspaper or gravel (I prefer newspaper for ease of cleaning). There are 17 different coquís on the island that range in color from green to yellow to brown with various accent colors. Presumably, it mates in the early summer and lays nine to 12 eggs two months after breeding. More importantly, wild snakes are not subject to captivity-induced stress. A 20-gallon terrarium for one large specimen (or several small ones) is ideal. It was another branch swaying softly in the wind.

I have seen large specimens feed regularly in small cages.

Baby snakes also make a quick meal for herons, chickens and other birds. A keeper should be aware that it is a slightly venomous snake. Alsophis is not a snake for leisure handling. “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. *This article originally appeared in the December 2000 issue of Reptiles magazine.
