Cuban Island ground boa
The Cuban Island ground boa is a non-venomous snake native to the islands of the West Indies, particularly Cuba. Classified as a protocubroid, or dwarf boa, it belongs to its own distinct family, Tropidophiidae. This species features smooth, scaly brown skin and has unique eye characteristics, including clear brilles instead of eyelids and vertically elliptical pupils, giving it a distinctive appearance. Typically growing between 1.5 to 3.3 feet in length, these snakes are adept at navigating their rocky environments and utilize their forked tongues to gather chemical signals for hunting and social interaction.
Cuban Island ground boas are carnivorous, preying on lizards, frogs, and small mammals, and are known to hunt in teams, particularly at the entrances of caves during the night. Their hunting strategy involves ambushing prey, such as bats, as they exit their roosts. While their mating habits remain largely unknown, they may reproduce through egg-laying or give birth to live young. These snakes have an average lifespan of at least 12 years and play a beneficial role in controlling pest populations, particularly rodents.

Cuban Island ground boa
The Cuban Island ground boa is a species of non-venomous snake native to the islands of the West Indies and Cuba. Even though the species is called a boa, Cuban Island ground boas are classified as protocubroids, or dwarf boas. These animals are their own distinct family. They are classified with the protucubroids for their small size.

Kingdom: Animalia
Phylum: Chordata
Class: Reptilia
Order: Squamata
Family: Tropidophiidae
Genus: Tropidophis
Species: Melanurus
Cuban Island ground boas have smooth, scaly, brown skin. Like other snakes, Cuban Island ground boas have brilles instead of eyelids. Brilles are transparent, or clear, eye coverings. These coverings sometimes give Cuban Island ground boas' eyes a glassy appearance. In addition to their odd eye coverings, Cuban Island ground boas also have unusual pupils. Pupils are the black areas of the eyes which open and close to let in light. Cuban Island ground boas have vertically elliptical pupils, like cats. Cuban Island ground boas grow to be between 1 1/2 and 3 1/3 feet (80 and 100 centimeters) long.
Cuban Island ground boas spend most of their time slithering around rocks and logs. As they move, they flick their forked tongues out to search the chemicals in their environments. Like other snakes, Cuban Island ground boas can pick up chemical signals with their tongues. These signals travel to their mouths and put in a special organ which is designed to figure out which chemicals are present. This information helps the dwarf boas trail prey, recognize predators, and find mates.
Not only are Cuban Island ground boas excellent hunters, they are sometimes known to hunt in teams. They will join with other similar boas and gather together at the entrance of caves. As the species is nocturnal, they rely on catching their prey by surprise at night. They have been observed arriving at cave entrances shortly before bats make their group exit.
Cuban Island ground boas are carnivores. This means they eat only meat. Their diet usually includes lizards, frogs, and small mammals like rodents. Once their prey is dead, Cuban Island ground boas wrap their jaws over the first part of the animal's body. They then use their sharp teeth to guide the prey inside and swallow it whole. Becauase Cuban Island ground boas hunt prey like rodents, they are helpful in controlling pest populations.
Nothing is really known about the mating habits of Cuban Island ground boas. They may lay eggs, similar to reptiles, or they may be ovoviviparous or viviparous like other reptiles. Ovoviviparous reptiles produce live young by hatching eggs inside their body before being born live, and viviparous reptiles produce live young through developing an embryo inside the mother's body.
Cuban Island ground boas have an average life span of at least 12 years.
