The Barbados threadsnake was first identified as a separate species in 2008 by S. Blair Hedges, a herpetologist from Pennsylvania State University.
[4] Hedges named the new species of snake in honor of his wife, Carla Ann Hass, a herpetologist who was part of the discovery team.
"[4] The photograph above shows L. carlae on a quarter dollar, a coin with a diameter of 24.26 mm (0.955 inches).
[8] Small species of snakes such as T. carlae have relatively large new-born offspring compared to adults.
[2] Based on the small number of known specimens and its distribution apparently being restricted to eastern Barbados, the continued survival of the species is a concern.
