The story of the missing camera: why the equipment was attached to the seals and what became known about their lives

The camera was attached to a seal as part of an extended study of seals from Sable Island. Devices for collecting biological and oceanographic data were attached to the animals — tracking tags, temperature sensors and cameras to document their movements and interaction with other marine species.

In total, eight seals were equipped with cameras — seven females and one male. The cameras are programmed to start recording under optimal feeding conditions: at night and at a depth of at least 25 meters from the surface. This way the camera will work longer.

The camera footage confirmed that the seals are looking for food on the seabed. Scientists also found out that seals cover a distance of up to 100 kilometers in search of food. Instead of wasting time and effort returning to the shore, gray seals often rest near the place of food extraction, sinking to the seabed and periodically surfacing to breathe.

After the camera disappeared, the researchers decided to place them only on pregnant females — this way they are more likely to be found on the island due to the appearance of offspring.

They are trying to repair the camera found now — it can tell a lot about the behavior of these amazing animals. By taking a closer look at the daily life of this species, researchers can uncover the secrets of gray seals and the marine life with which they coexist.
