Sea Turtles Nesting: The Surprising Inspiration for Satellite and Nano Technology Innovations
Introduction
Earlier this week, I saw the remnants of a sea turtle making the migration out of the water and laying their eggs in the sand. The above picture shows its flippers moving to find the location for the turtle to lay its eggs. This usually happens at night so it’s exciting for residents in coastal cities to find in the morning during season!
It made me think about the “why does this happen?”, “how does it happen?” and “how can it be applied to other industries like nano technology and satellites?” So in this blog, we’ll explore the intriguing world of sea turtles as they lay their eggs on sandy beaches and witness the miraculous emergence of hatchlings. We delve into the timing and reasons behind their nocturnal nesting habits, examine the remarkable duration of the incubation period, and unravel the mystery of how these tiny creatures instinctively know what to do when they hatch. And last, we’ll explain what we can learn from their internal instincts to apply to nano technology and satellites, including:

Turtles Hatching Process:
1. The Nighttime Ritual: Timing and Behavior
Sea turtles have a unique preference for nesting during the nighttime, and this behavior holds several advantages for their survival and the successful hatching of their eggs.
Sea turtles typically nest during the darkness of the night, seeking the cover of darkness to avoid potential predators. This nocturnal habit reduces the risk of predation, as many natural predators are less active or unable to see well in the dark. Additionally, nesting at night allows sea turtles to take advantage of cooler temperatures, minimizing the risk of heat stress to both the adult females and their developing eggs.
2. The Egg-Laying Process: Timing and Duration
The timing of sea turtle nesting varies among species and regions, but it generally occurs during specific seasons influenced by environmental cues. Most sea turtle species nest in the same area where they were hatched, an extraordinary navigation feat that remains largely unexplained.
Typically, sea turtles lay their eggs on sandy beaches during the warmer months of the year. The timing of nesting is influenced by factors such as water temperature and lunar cycles. While exact timing may differ, nesting often occurs between May and September in many coastal regions.
Once a female sea turtle finds a suitable nesting site above the high tide line, she digs a nest cavity using her rear flippers. This process involves precise movements and careful excavation to create a safe space for her eggs. After depositing the eggs, the female covers the nest, camouflages it, and returns to the sea.
3. The Incubation Period and Hatchling Instincts
Following the egg-laying process, sea turtle eggs undergo a period of incubation that typically lasts between 50 and 70 days, depending on the species and environmental conditions.
Throughout the incubation period, the developing embryos rely on the surrounding temperature to determine their gender. Warmer temperatures tend to produce more females, while cooler temperatures favor the development of males. This temperature-dependent sex determination adds another layer of complexity to the already fascinating process of sea turtle nesting.
When the time comes for the hatchlings to emerge, they rely on a combination of environmental cues and innate instincts. As the hatchlings continue to develop inside their eggs, they can sense vibrations and changes in temperature. These cues indicate that it is time to prepare for hatching.
Using a specialized egg tooth, located on the tip of their snout, the hatchlings begin to break through the shell. This process, known as "pipping," requires strength and determination. Once a hatchling successfully breaks free, it begins the arduous journey to the ocean.
The hatchlings instinctively move towards the brightest horizon, which is typically the reflection of the moon or starlight on the water. This natural light guides them towards the ocean, where they face numerous challenges and predators. Only a small percentage of hatchlings will survive to adulthood, emphasizing the significance of their incredible journey.
How Does This Inspire Innovation in Nano Technology and Satellites?
