Biology

Did you know that sea turtles have a built-in compass? Magnetic compasses are important for navigation; they enable people to tell directions by using Earth’s magnetic field. Loggerhead turtles (Caretta caretta) must stay within the North Atlantic Gyre, the circular ocean current system that surrounds the Sargasso Sea. Biologists tested these turtles by putting them in water tanks surrounded by electric coils that generated an artificial magnetic field. As they changed the variables, they found that the turtles again and again would swim to where they thought the gyre was.

The conclusion is that these sea turtles use magnetic measurements to stay in the North Atlantic Gyre. Did a compass happen by accident and chance? When you see a compass, you know there must be a compass-maker. God cares for His sea turtles by giving them built-in compasses.

The sea is his, and he made it:….
