We had no new turtle activity and the remaining nests in our zone aren't due to hatch until August.

Sea Turtle Egg Smuggling
Saturday, July 25, 2009
Males or Females, That's the Question
For loggerhead sea turtles, the warmer eggs toward the top of the nest, closest to the sunlight, generally hatch as females while the ones in the cooler sand at the bottom of the nest generally hatch as males.
Data collected in 2002 and 2003 on Sanibel showed 20-60% of hatchlings from the monitored nests were male, higher than all other Florida beaches except for Miami Beach.
Another year of data collection is needed to statistically show Sanibel's tendency to produce males.
A total of 10 nests are being selected during the 2009 nesting season to have a temperature sensor buried in the egg chamber. The sensor records the temperature in the nest for the duration of the incubation period. Near the estimated hatch date of a nest, a cage will be placed over the egg chamber to catch the hatchlings. Ten of the strongest hatchlings will be taken for a study that is being done as part of the Sea Turtle Research, Monitoring and Protection Program at the Florida Atlantic University and the University of Alabama. Those 10 turtles will be raised in their lab until they are old enough to be sexed. The rest of the hatchlings will be released.
Hopefully those studies will help answer the question, why Sanibel produces more male Loggerhead sea turtles.

Walk #12






(Much better if you enlarge the photos.)



The hatchling had a problem when he tried to pass a shallow sand hole that had been washed over by the waves. He slid sideways and then flipped over onto his back. Poor thing tried and tried but couldn't get turned over. I finally helped him and he was once again on his way. This is a perfect example of the problem caused by leaving holes on the beach. I wish there were some signs posted at the beach accesses etc. with warnings about them. I know some people just refuse to follow rules, but I think they would help.
The videos are not the greatest quality because they are from my phone. (There is a problem with the video camera, as it was dropped and in need of serious repair.) You can view these in HQ on YouTube.
Follow the tiny turtle as he makes the remainder of his walk to the water. Just after the first wave came in near him, it looked like he hesitated and then thought, I've got to do this, and went for it. I saw his head come up four times at the top of each wave and then he was gone.
After the little turtle swam away, I looked around and saw that the sun had just come up.

Sea Turtle Eggs Being Stolen
The only people legally allowed to handle sea turtles or eggs include those associated with aquariums, marine facilities, museums, conservation societies, research institutions, universities or colleges or those who have obtained proper accreditation and necessary licenses for working with marine reptiles. If you are not working with a respected or accredited organization you will be prosecuted for handling or disturbing sea turtle eggs.
Besides taking eggs, other offenses include any action that kills, harms, or injures marine turtles. It also involves any activity that disturbs the nesting grounds, breeding places, or natural immediate habitat of marine turtles. It is against Florida law to take, disturb, mutilate, destroy, sell, transfer, molest, or harass sea turtles, sea turtle eggs, or sea turtle nests.
It is a felony crime in the state of Florida to disturb sea turtle nests or to remove sea turtle eggs. The Fish and Wildlife Conservation Commission has legal authority to investigate any cases of sea turtle poaching, abuse, theft, or disturbance.
Sea Turtles protected by Florida law are: Loggerhead, Green, Leatherback, Hawksbill , and the Ridley Turtle.
Penalties for violating Florida’s, Marine Turtle Protection Act include a fine of $100.00 per egg. Possession of 11 or fewer sea turtle eggs is classified as a first-degree misdemeanor and those charged will face punishment according to Florida law. Second and third offenses may result in prison time and much larger fines.

Walk #11
One lady told me that she had been coming to the beach everyday to see if that nest had hatched yet. The other lady said that we had a turtle crawl in our zone; but as it turned out, it was a little way further and in the next zone.
Walking out the Buttonwood access I could see a big cloud, hanging pretty low over the water.
View looking toward the Sanibel Lighthouse.
There was a lot of seaweed on the beach, not red algae but almost the same color. I think it is Sargassum, but it looks more red than what we've been seeing. I also saw more Manatee Grass in a few areas. There were hundreds of tiny flies around the seaweed. A lady walking past me said, "It's a buggy morning."
This hole was 2 1/2 to 3 feet deep. It wouldn't be safe to walk on the beach in this area because you could loose a leg. There were several of these scattered around, making the beach look like an obstacle course.
MAN DOWN!!! I knew eventually someone would get down in one of those sand holes.
Two race cars had collided, flipping one over on it's side. I hope no one was hurt.
I picked up three plastic sand pail handles and one sand pail. This turtle was ready to eat one, but I grabbed it, just in time, to add to my growing collection of trash. Items found most often are: tissues, baby wipes, foil juice containers, the straws and cellophane wrapper, popsicle wrapper, gum wrappers, broken beach toys, and flip flops.
I picked up another fillet of sole. I sure hope you don't need a permit to do that.
I think this is deserving of the title of sand and shell art.
Yesterday when my grandsons were out in the water they picked up some chunks of sargassum and found a tiny crab and 3 very tiny fish, hiding in it. It shows you how important this seaweed is to wildlife.
You can make up your own conclusions for this one. A candle and two empty bottles on the beach???

We were hoping to see tiny turtle tracks heading toward the Gulf, but the nest still hasn't hatched.
