Scientists Explain How Eyes Help Blind Sands Feel Magnetic Field

As part of the study, scientists have established how blind sands can sense the magnetic field. It turned out that their eyes help them in the appropriate actions.

Ansell's peskoroi are related to naked mole rats, they see practically nothing and prefer to live underground, where they build complex passages and settle there in families. The length of the tunnels dug for these animals is the most impressive, and their dwellings are invariably directed from north to south. This feature may serve as evidence that rodents are guided by the magnetic field. Magnetoreception is a normal characteristic for many members of the fauna.

In the new work, staff at the University of Duisburg-Essen experimented with sands, removing the eyes of some young individuals. After that, they could continue growing up in their usual conditions. The absence of visual organs did not affect the socialization or behavior of animals. The next stage involved digging tunnels by rodents in controlled conditions, where scientists could control, among other things, the magnetic field.

As a result, the slugs from the control group were oriented along the lines between the poles. Animals with distant eyes dug, choosing a direction in a random order, which had nothing to do with the external magnetic field.
