Silicon-based turtles slowly sank into the water, swimming towards the depths of the ocean. Not far from the coastline, they caught underwater currents, drifting along with them. Silicon-based turtles are not carbon-based life forms, hence they do not need to surface for air and can stay submerged for months at a time. Except for a monthly venture to the surface to forage on some islands, they spend the rest of their time riding the currents.
Due to the numerous predators in these seas, the journey is fraught with danger, and young silicon-based turtles are at the bottom of the food chain. Reaching a new land even a day earlier means gaining safety sooner. To avoid predators in the shallower waters, silicon-based turtles mostly stay in the lower layers of the currents, that is, in the mid to lower regions of the ocean, thousands, even three thousand meters below the surface.
