How Do Sea Turtles Navigate? Scientists have long known that the turtles, like many animals, navigate at sea by sensing the invisible lines of the magnetic field, similar to how sailors use latitude and longitude. Now a new study has the answer: The turtles also rely on Earth’s magnetic field to find their way home.
How do sea turtles navigate around the world? Young sea turtles use the Earth’s magnetic field as a source of navigational information during their epic transoceanic migrations and while homing. A new study using satellite telemetry has now demonstrated for the first time that adult turtles also navigate using the Earth’s magnetic field.
How do sea turtles navigate off the beach? After emerging from their nest, the turtles use visual cues to locate the surf zone, the motion of waves in shallow water to swim, and finally in deep water the earth’s magnetic field (where the waves no longer reliably indicate an offshore direction).
Do sea turtles use true navigation? These findings support the suggestion, from previous laboratory work, that turtles use a crude true navigation system in the open ocean, possibly using the earth’s geomagnetic field.
” It allowed them to explore in more detail how turtles make their way to such small and harder-to-find islands.

Instead, they learn their way using a number of different cues: visual cues (light), kinetic cues (wave motion) and finally, magnetic ones, that let them make their way to the ocean and, eventually, navigate their way home.

Do turtles lay eggs in the same place every year?
They can lay hundreds of eggs in a nesting season—thousands in a lifetime! Among species, scientists have determined that turtles lay their eggs in the same time and place but not necessarily returning year after year.
Why do sea turtles cry?
As reptilian kidneys are unable to excrete large volumes of salt via urine, sea turtles evolved specialised secretory glands (lachrymal glands) located in the corner of each eye to remove excess salt. The liquid secreted gives the appearance of tears, hence why turtles are often reported to “cry” .
