Why Do Sea Turtles Come Out Of The Water: Sea turtles, magnificent and ancient creatures that have roamed the world’s oceans for over 100 million years, often leave their watery realm and venture onto land. This intriguing behavior has long piqued the curiosity of researchers, environmentalists, and nature enthusiasts alike. In this exploration, we delve into the fascinating phenomenon of why sea turtles come out of the water.
While it might seem counterintuitive for marine animals to leave their life-sustaining habitat, sea turtles have compelling reasons for doing so. These creatures, known for their distinctive flippers and protective shells, embark on these terrestrial journeys for various essential purposes. Understanding these motivations not only sheds light on their unique behaviors but also helps us appreciate the intricate web of life within our oceans.
Sea turtles are renowned for their remarkable migrations, crossing vast stretches of ocean to lay their eggs on specific nesting beaches. This nesting process is a critical aspect of their life cycle, and it requires them to temporarily forsake the sea. Additionally, sea turtles occasionally venture onto land for other activities, including basking to regulate their body temperature and engaging in vital courtship rituals.
Throughout this exploration, we will unravel the mysteries surrounding these ancient mariners’ terrestrial excursions, gaining insights into the ecological significance and conservation implications of their behavior. Understanding why sea turtles come out of the water is not only a testament to their resilience but also a testament to the marvels of the natural world.
Why do turtles come out of the ocean?
Sea turtles eggs must incubate in moist sand. For this reason, every year, some beaches around the tropical and temperate world are visited, mostly at night, by adult females who come ashore to dig a nest chamber and there, deposit their eggs. It is a common belief that only females come ashore.
Turtles come out of the ocean for a variety of essential reasons deeply ingrained in their evolutionary history. One of the most significant motivations is nesting. Female sea turtles, after reaching maturity, embark on remarkable journeys to return to the very beaches where they hatched. This nesting behavior is an age-old tradition, ensuring the continuation of their species.
Another reason for their terrestrial ventures is basking. Turtles are ectothermic, meaning they rely on external sources of heat to regulate their body temperature. Basking on the sun-warmed shores allows them to elevate their body temperature, aiding digestion and providing energy for their next aquatic endeavors.
Additionally, courtship rituals play a crucial role in their terrestrial activities. Male turtles may come ashore to compete for the attention of a female, engaging in complex displays to win her favor.
Turtles’ occasional excursions onto land are a testament to their remarkable adaptability and the finely tuned strategies they employ for survival. Understanding these behaviors not only enriches our knowledge of these ancient creatures but also underscores the importance of conserving their habitats and protecting them from the many challenges they face in today’s changing world.
Why do sea turtle come to the surface of water but not very often?
Sea turtles spend most of their lives submerged in an aquatic environment, but they also can spend significant amounts of time at the surface of the water because they require air to breathe. In addition, new hatchlings and nesting females spend time, however brief, on the beach.
Sea turtles, remarkable marine creatures, have adapted to a life primarily underwater, but they do come to the surface periodically, though not very often. These infrequent surface visits serve several crucial purposes in their survival and behavior.
Sea turtles are air-breathing reptiles, and they require oxygen to sustain their metabolic processes. When they dive and forage underwater for extended periods, they accumulate carbon dioxide and deplete oxygen levels within their bodies. To replenish their oxygen supply, they come to the surface to take a breath.
Sea turtles use the surface for navigation and orientation. When they surface, they may briefly assess their surroundings, take note of celestial cues like the sun’s position, and even imprint their location for future reference. This helps them return to their nesting beaches, foraging areas, and migration routes accurately.
Lastly, surface visits can serve thermoregulatory purposes. Sea turtles may bask at the water’s surface to raise their body temperature, especially in cooler waters, which aids digestion and maintains their overall health.
While sea turtles spend the majority of their lives submerged, these periodic surface appearances are vital for their survival, navigation, and well-being in the dynamic marine environment they call home.
Why do turtles hatch at night?
Hatchlings usually wait until night to emerge from the nest. Emerging at night reduces exposure to daytime predators. Studies have shown that some nests will produce hatchlings on more than one night. For most sea turtle species, undisturbed nests can have more than 90% of the clutch successfully hatch.
Turtles hatch at night for a variety of reasons that are closely tied to their survival and ecological adaptation. This nocturnal hatching behavior has evolved over millions of years and offers several advantages for these remarkable reptiles.
One primary reason for night-time hatching is to minimize predation risk. Many predators, such as birds and crabs, are diurnal (active during the day), and their reduced activity at night provides hatchlings with a safer window of opportunity to make their way from the nest to the ocean. The cover of darkness helps shield the vulnerable hatchlings as they scuttle across the beach.
Another crucial factor is temperature. The sand on the beach can become extremely hot during the day, potentially reaching temperatures that are lethal to turtle embryos. By hatching at night, when the sand is cooler, turtle hatchlings reduce their risk of overheating and increase their chances of a successful emergence from the nest.
Moonlight plays a significant role. Many turtle species use the reflection of moonlight on the water’s surface to orient themselves towards the sea. The brighter moonlight provides a clear and consistent visual cue that guides the hatchlings in the right direction.
The choice of night-time hatching is a remarkable example of how these ancient reptiles have adapted to optimize their chances of survival in a world filled with natural challenges.
Can sea turtles sleep underwater?
Sea turtles can sleep at the surface while in deep water or on the bottom wedged under rocks in nearshore waters. Many divers have seen green turtles sleeping under ledges in reefs and rocks.
Sea turtles possess a unique ability to sleep underwater, but it’s not quite the same as the way humans or other animals sleep. Instead, sea turtles engage in a behavior known as “resting.”
Sea turtles are air-breathing reptiles, which means they must periodically come to the surface to breathe. They can hold their breath for extended periods, but they eventually need to replenish their oxygen supply. During their resting periods, they remain submerged but at a level where they can easily surface for a breath when needed.
The specifics of sea turtle resting behavior can vary among species, but generally, they find a comfortable spot underwater, often wedging themselves under a rock or in a crevice, and then enter a state of reduced activity. During this time, their metabolic rate drops, allowing them to conserve energy. While in this resting state, they continue to swim and move, but at a much slower pace than when they are actively foraging or swimming.
This adaptation allows sea turtles to rest and conserve energy while avoiding some of the risks associated with being at the surface, such as potential predation or exposure to unfavorable weather conditions. It’s a fascinating aspect of their biology that enables them to thrive in their marine environments.
What can humans do to protect adult sea turtles?
Keep nesting beaches dark and safe for sea turtles. Turn off, shield, or redirect lights visible from the beach. Lights disorient hatchling sea turtles and discourage nesting females from coming onto the beach to lay their eggs. Do not disturb nesting turtles, nests, or hatchlings.
Protecting adult sea turtles is crucial for their survival and the health of marine ecosystems. Several measures can be taken by humans to help ensure the well-being of these magnificent creatures:
- Reduce Plastic Pollution: One of the most significant threats to sea turtles is plastic pollution. Humans can minimize plastic waste by using reusable items, reducing single-use plastics, and properly disposing of trash. This helps prevent turtles from ingesting or becoming entangled in plastic debris.
- Responsible Fishing Practices: Commercial and recreational fishing can inadvertently harm sea turtles through bycatch or entanglement in fishing gear. Using turtle-friendly fishing gear, such as hooks with barbless designs and implementing bycatch reduction measures, can greatly reduce the impact on these animals.
- Coastal Development Management: Proper planning and regulation of coastal development can protect nesting habitats for sea turtles. By preserving natural shorelines, implementing turtle-friendly lighting, and establishing buffer zones around nesting sites, humans can create safe environments for nesting females.
- Educational Initiatives: Raising awareness and educating communities about sea turtle conservation is vital. Teaching people about the importance of not disturbing nesting turtles, reporting injured or stranded turtles, and supporting local conservation efforts can make a significant difference.
By taking these actions and promoting responsible stewardship of our oceans and coasts, humans can play a vital role in safeguarding adult sea turtles and ensuring their continued presence in our oceans.

Coastal development, pollution, and climate change have led to the destruction of nesting sites and foraging grounds, disrupting their natural life cycles.
Light pollution poses a grave danger to hatchlings. Artificial lights on beaches disorient them, causing them to veer away from the safety of the ocean and towards dangerous roads or predators. Moreover, beach litter, especially plastic debris, presents a grave hazard. Turtles may ingest or become entangled in discarded plastics, leading to injury or death.
Human activities also contribute to the peril faced by sea turtles. Nest poaching remains a concern in some regions, as eggs are harvested for consumption or illegal trade. Additionally, inadvertent bycatch in fishing gear is a major threat, leading to injuries and fatalities among these gentle creatures.
Boat strikes are another significant danger. As sea turtles surface to breathe, they often encounter vessels, resulting in collisions that can be fatal or cause severe injuries. This is particularly common in busy coastal areas.
Lastly, climate change alters nesting beaches and affects sea turtle sex ratios, as temperature determines the sex of the hatchlings. Rising temperatures can lead to skewed ratios, potentially impacting population dynamics. Collectively, these threats underscore the urgency of conservation efforts to safeguard the future of these ancient marine species.
