When we leave familiar areas, we might need a moment to reorientate ourselves. Similarly, oceanic manta rays, the largest species of ray which travels thousands of kilometers between habitats, may need to gather information about their new surroundings after moving away from the coasts. They are capable of diving to extreme depths, up to more than 1,200 meters – and a new study showed that this behavior might help them navigate across the open ocean. These extreme dives could help the animals sample environmental cues and allow them to travel between ecosystems.
