There’s nothing like the excitement of new life. Scooping out the final handful of cool sand to reveal the first couple of pristine, squishy white eggs, it was a complete thrill to know that soon there would be a mass of tiny loggerhead sea turtles hatched out and running toward the sea.
Watching the Sarasota sun rising in the sky as we completed documenting and recording every detail of the nest, I felt the wave of sickness in my tummy starting to shift too. It was morning sickness. Like the tiny little lives flourishing inside the eggs of the sandy nest we’d been recording, there was a tiny life flourishing inside of me too.
Even without eating breakfast, the 6am sea air churned my stomach. But it was worth it to join the Mote Marine Laboratory‘s turtle patrol team. I was on one of my first field assignments for National Geographic Kids magazine; to explore the local marine life in Florida, and I didn’t want anything to get in the way!

Joining Mote’s sea turtle nest monitoring team on Venice Beach, Sarasota was a fantastic assignment. Finding the newly dug egg chambers, having the opportunity to actually see the eggs — and then protecting the nests from unsuspecting beachgoers who may accidentally stand on them — was a very moving experience.
As a soon-to-be mum; seeing the effort that these incredible turtle mothers go through to find the perfect nesting spot to give their young the best chance at life brought a tear to my eye! (ok, lots of things brought a tear to my eye when I was pregnant, but this truly was special).
Out and about with the Mote team
I learnt that over the previous year’s nesting season, Mote’s Sea Turtle Conservation and Research Program reported that Longboat Key through Venice hosted a total of 4,588 nests (beating the 2015 record by 2,103 nests), showing this thriving nesting area’s importance to the local sea turtle population.
Shifting sands and moving nests
Sometimes, when the nests are in a spot that may be affected by human impact, such as beach nourishment, it’s necessary for the Mote team to move them.
A nourishment project takes place where there is a need to place fresh sand on the beach. It takes a while for the turtles to get used to the new sand, because its texture and height can be different and create obstacles.
Following the previous year’s nourishment project on Venice beach, the turtles would not come very far up the sand. There were almost three times as many false crawls (where a mother comes onto the beach to lay her eggs, but returns to the sea without actually nesting) as there were nests.

in 2016, the team had to relocate 200 nests! Which meant moving up to eight a day. This is no easy feat when there’s a tight deadline to move nests by 9.30am, before visitors and tourists come to the beach.
Apparently it takes an hour to find all the eggs, dig them all out of the sand, and put them all back in at the new location. Of course eggs have to be moved extremely delicately and carefully, as the team don’t know exactly when the eggs were laid overnight.
To make the task even more complex, when a new nest chamber is dug, it must be exactly like that which the mother created.
“You have to measure it perfectly and dig a new one exactly the same,” Mote’s Kirsten Mazzarella tells me. “And you have to find a spot that’s not going to have a predators and a place that doesn’t have any lighting to draw them in the wrong direction. You don’t want to move them to a worse spot than where the mum laid them.”

Mote feel very strongly about creating nests the way that mother’s intended, as they try not to interfere with nature. Moving nests is not something they like to do, as usually the mother has picked the best natural spot and they may be moving it to a less desirable area. If the mother has picked a bad site, they don’t like to move this either, as that’s nature’s way of saying the genes were not meant to be passed on.
“We take care of human impact, but not nature’s impact,” Kirsten explains. “We used to move the nests that were too close to the water higher up the beach, but now if the mother turtle gets it wrong, we allow nature to take its course. The only time we actively move a nest is when a nourishment project of the sand is actively taking place. That requires the nourishment people to get a special permit and then contact Mote to do the work.”
Turtle treatment and recovery
Mote work hard to reduce human impact and help the turtle populations in other ways too. They own one of only three wildlife hospitals in Florida with special facilities and training to care for turtles suffering from fibropapilloma tumors.
Because scientists are still learning how the disease is transmitted among turtles, they must provide a separate facility just for animals with these tumours.

Tumours can grow on the surface of the flippers, inside the mouth (affecting feeding), and on the turtle’s eyes. All tumours are removed by laser surgery, though the animal must have at least one salvageable eye after removal of the tumours in order to be released back into the wild.
It was an incredible and emotive experience to be allowed behind the scenes in this amazing facility, which really is changing the lives of these beautiful animals. The care and attention delivered by staff is admirable, and I don’t quite know what the outcome would be for the injured and sick turtles if it weren’t for Mote.
It’s also fascinating to discover how far the facility has come and what they have learnt in the day-to-day handling of its patients.
Up until 2010, they used to have to keep turtles in the centre for a year after their tumour-removal surgery, to ensure they were not contagious. If they had a re-growth of any tumours, they would have to start that clock again.
This meant that some animals were being kept at the facility for two years and more! But in 2010, Sarasota had an outbreak of red tide (a harmful algal bloom), which saw the hospital inundated with patients, so they made the decision to release turtles with the disease as soon as they healed from surgery.
Over time they learnt that the virus comes out in times of stress, so keeping them in captivity to ensure they were healed was actually creating a vicious cycle where they ended up getting more tumours instead of recovering.
I learnt so much about Mote’s projects and Sarasota’s different species of turtle (loggerhead, leatherback, green turtle, hawksbill and Kemp’s ridley) on my trip — all of which are mentioned in my Nat Geo Kids article. If you’d like to read about them and much more about the turtle nesting patrol and turtle hospital (I’ve tried to keep the content of this blog post quite different from the article), the May issue is out now!
