The family Leptotyphlopidae, commonly known as slender blind snakes, is a group of small, thread-like snakes that are found throughout the world. These snakes are unique in their physical appearance and behavior. As their name suggests, they are slender in shape and lack the ability to see, so they rely heavily on their sense of smell to navigate their surroundings. Other synonyms for this family of snakes include threadsnakes, worm snakes, and slender snakes. Despite their small size and elusive nature, they play an important role in their ecosystems as predators of small invertebrates such as ants, termites, and other arthropods.
