MCQ Detailed View

Blind snakes are small, burrowing reptiles that look very similar to earthworms. They are called “blind” because their eyes are tiny and not well developed, making them poor at vision. Instead of relying on sight, blind snakes use their strong sense of smell and touch to move through soil and find food. Their diet mostly consists of ants, termites, and insect larvae, which makes them useful in controlling pests.

One of the most interesting facts about blind snakes is their unusual relationship with owls. Certain species of owls, such as the Eastern screech owl, are known to bring live blind snakes into their nests. Unlike other prey items, the owls do not eat these snakes. Instead, they allow them to live in the nest alongside their chicks. The blind snakes feed on insects, larvae, and other small pests that might harm or disturb the baby owlets. In this way, the snakes act like natural cleaners for the nest.

This behavior is an example of a mutualistic relationship in biology. The blind snakes get protection and a safe environment to live in, while the owls benefit from a healthier and cleaner nest for raising their young. Scientists have observed that nests with blind snakes tend to have stronger and healthier chicks, as they are less exposed to harmful pests.

The other options in this question—woodcutters, eagles, and parrots—are incorrect because they do not have this unique relationship with blind snakes. It is specifically owls that are known to “keep” blind snakes almost like pets, although in scientific terms it is more about mutual benefit rather than true domestication.

This example highlights how different species can interact in surprising ways and how even small, less noticeable animals like blind snakes play an important role in the ecosystem.
