Sea turtles are commonly associated with U.S. coastal ecosystems, particularly for nesting on sandy beaches.

Sea turtles, including species like the loggerhead and green sea turtle, are frequently found in U.S. coastal ecosystems. These marine reptiles are known for nesting on sandy beaches along the U.S. Atlantic and Pacific coasts. Their presence highlights the importance of these coastal habitats for their lifecycle, including nesting, hatchling survival, and migration. While polar bears are associated with Arctic environments, bald eagles and deer are more commonly linked to inland habitats or non-coastal ecosystems.
