About Amphisbaena munoai
Amphisbaena munoai: The Munoa Worm Lizard
The Munoa worm lizard, scientifically identified as Amphisbaena munoai, is a small reptile belonging to the amphisbaenian group within the family Amphisbaenidae. This species is native to the southern regions of South America, specifically inhabiting the temperate grasslands of the pampas biome found in southern Brazil and Uruguay. It prefers to live at elevations ranging from 100 to 500 meters above sea level.
Physical Characteristics and Behavior
Amphisbaena munoai is characterized by a rounded head and a body segmented into distinct annuli. The number of body annuli typically ranges from 202 to 218, with 18 to 25 caudal annuli. Each annulus at midbody contains between 10 and 14 segments. This species is primarily terrestrial and fossorial, meaning it spends most of its life underground or burrowing. It is often observed hiding beneath stones or decaying bark, a behavior that allows it to regulate its body temperature while remaining protected from potential predators.
Diet and Reproduction
The diet of the Munoa worm lizard largely consists of termites, supplemented by various small insect larvae. Its reproductive cycle is seasonal. Females are capable of being fertilized between June and October, a period during which males exhibit a significant increase in testicle volume. The females carry their eggs from November to December, suggesting that copulation likely occurs between September and November. Notably, the eggs of A. munoai are frequently discovered within ant nests.
Etymology
The specific name, munoai, was chosen to honor the Uruguayan zoologist Juan Ignacio Muñoa, who lived from 1925 to 1960.
