Caretta caretta…no, it’s not a song

It’s a fair-weather day.

A battalion of brown pelicans coast overhead on dark arched wings. Children build sand castles and bob in the surf, and shorebirds rest in warm dunes—a feast of beauty and abundance.

Santa Rosa Island was named in homage to Isabel Flores de Oliva – the “Rose of Lima.” She was canonized by the Catholic Church in 1671 as Saint Rose.

Pensacola is rich in stories.

Take the story of Caretta caretta for example. She doesn’t even know we’ve tagged her with a dichotomous name to set her species apart from others. Her only inclination is to find a darkened shoreline and lay her burden down.

Buoyed by thick ocean waves she paddles with strong legs through the currents.

Through heavy lid, she looks toward shore and vaguely remembers its smell and warm, gritty touch. The moonlit shore is quiet as she takes purchase on the shifting sand below her.

She looks from just under the water along the beach head where bright lights in hotels and restaurants, homes and gas stations could make her decide to turn away. She looks for a darkened beach, lit only by the silver moonlight. It’s instinctual.

Every May through September along the Gulf shores, female loggerhead turtles (Caretta caretta) return to lay leathery eggs in the dunes of their birth.

Kemp’s Ridley, Atlantic green turtles and sometimes leatherbacks also use these crystal white beaches as a nursery. It’s been so for thousands of years.

Caretta caretta has spent her youth in the Sargasso Sea, a body of water created from currents in the North Atlantic and where Sargassum seaweed covers over its surface. It is believed the loggerhead turtle feeds and grows in this protective cover.

When she comes of age, dozens of eggs grow within her as she heads back to the same beach where as a hatchling she was just the size of a quarter and prize catch of shorebirds, crabs, and other beachside predators. She is one of the few lucky infant turtles that managed to survive to adulthood.

Now she returns to lay down the next generation. And, should she come ashore, will she struggle to navigate beach chairs, plastic inner tubes, or sandcastles?

What will happen to her offspring? Baby sea turtles are attracted to bright lights, an instinct that should turn them toward a moonlit sea. Will they head toward the hotel lights instead? Rangers report scores of tiny turtles destroyed by cars or desiccated in the hot sun among buildings.

In today’s world, with the human built environment, it takes countless volunteers to tend turtle nests, redirecting the young toward the ocean. Because of this, can we say that these species are self-sustaining?

There are seven species of sea turtles in the world today. Four of them lay their eggs here. That constitutes a biological treasure for this region, a remaining strand of a once diverse web of life just off these shores.

What if Caretta caretta disappears due to human interference in this annual ritual that replenishes her kind? Should we really care?

Reach back 100 years in Pensacola history to an ocean teeming with life. Fish would be larger and more plentiful and you could scoop up shrimp in the bay with your hands. There would be hundreds more dunes with waving sea oats, both habitat and nursery to many species.

The loggerhead turtle is part of an ocean web that supports our fishing industry. The biodiversity of our beautiful islands is the basis of tourism, a principal industry. Somehow we have to learn to maintain this natural treasure while going about our business.

We are working that out now. There has got to be a way. Pensacoleans have never been short on ingenuity.

For Caretta caretta we can turn down the lights, sit out on our decks and listen to the oncoming waves. We’ll save money by reducing energy consumption and get a better view of the heavens. Let’s face it: life would be dismal without the beauty of nature.

When we see a dolphin breach the waves, white terns dive and soar, or listen to ocean breezes, we are renewed and encouraged that all is right on this exquisite planet we are so fortunate to share with other species.

Caretta caretta…no, it’s not a song. It’s a symphony.
