About Amphisbaena fuliginosa
Amphisbaena fuliginosa, commonly referred to as the black-and-white worm lizard, speckled worm lizard, or spotted worm lizard, is a species of amphisbaenian notable for its striking appearance and fossorial lifestyle. Its ecology remains largely enigmatic due to its habit of living underground, but its distinctive white and black mosaic pattern provides easy identification.
Geographic Range and Habitat
This species is distributed across northern South America, encompassing the island of Trinidad and extending southwards into the Brazilian Cerrado biome, with its southernmost recorded locations in Minas Gerais and Goiás. Amphisbaena fuliginosa is found within Amazonian forest areas, where it makes its home beneath the surface.
Physical Description and Behavior
Adult Amphisbaena fuliginosa typically reach a total length of 30 to 45 centimeters (12 to 18 inches). Its most defining characteristic is the intricate mosaic pattern of white and black scales that adorns both its dorsal and ventral sides. As a burrowing and nocturnal species, it spends the majority of its existence underground. Its diet consists of a variety of small invertebrates and insects it encounters during its subterranean foraging, including beetles, ants, termites, spiders, centipedes, millipedes, crickets, and grasshoppers. Occasionally, it may also prey on small vertebrates and consume egg shells.
Reproduction and Cultural Significance
Amphisbaena fuliginosa reproduces oviparously, meaning it lays eggs. Beyond its biological characteristics, the species holds a place in Yanomami mythology. According to their lore, amphisbaenas are said to emerge from the spinal columns of warriors killed in battle and are believed to have a supernatural connection to the underworld. Traditional Yanomami customs involve questioning an encountered amphisbaena to ascertain its intentions based on its vocal response.
