Belize's Sea Turtles: Hatching Season

Sea turtles in Belize hatch in the summer, but they can also hatch in the winter. The female turtles lay their eggs in nests that they dig in the sand using their back flippers. The eggs hatch after an incubation period of 30 to 90 days. The baby turtles then dig their way to the surface, which can take up to a week, and they usually emerge from their nests at night.

Sea turtles hatch in the summer and winter

The incubation period for sea turtle eggs is between 60 and 90 days. The length of time depends on the weather. The eggs develop faster in warm years, and the young may hatch and emerge as early as mid-August. In cooler years, the eggs may hatch later in the fall. The hatchlings usually emerge from their nests at night, and it may take them three to seven days to dig their way to the surface after hatching.

Even before the eggs hatch, they face many natural threats. They fall prey to predators such as wild dogs, raccoons, skunks, and birds that feed on the eggs. The turtles that make it to the hatchling phase still have to deal with predators in and out of the sea. As adults, they may be afflicted with a potentially fatal tumour disease known as marine turtle fibropapilloma, the cause of which is still unknown.

In addition to natural threats, sea turtles in Belize face significant dangers caused by humans. The harvesting of turtle eggs for sale and consumption still occurs in some coastal communities. Another threat is the accidental capture and drowning of turtles in fishing gear such as gill nets, shrimp trawlers, and long lines. The construction of sea walls, piers, and tourist developments also poses a major risk to their habitat.

Despite these challenges, there are efforts to protect and conserve sea turtles in Belize. The country has protected sea turtles since 1993, and there are specific conservation programs in place, such as the Ambergris Caye Master Plan, which includes close monitoring and protection of nesting grounds. Additionally, profits from eco-tourism and research trips contribute to conservation efforts and help save hatchlings at turtle nesting beaches.

Eggs hatch in 60-90 days

The incubation period for sea turtle eggs in Belize is 60 to 90 days. During this time, the eggs could fall prey to hazardous conditions. They could be eaten by dogs, raccoons, skunks, or birds that feed on the eggs.

The female sea turtle makes a long journey to land and then a trek up the beach to lay her eggs. She chooses a well-protected area, above the high tide line, and begins the arduous process of digging the nest. She will lay up to one hundred eggs.

Once the eggs are laid, it may take three to seven days for the young turtles to dig their way to the surface. The hatchlings usually emerge from their nests at night. They make the treacherous trip down the beach and into the sea.

Even before the eggs hatch, they face a number of natural threats. They fall prey to predators such as wild dogs, raccoons, skunks, and birds that feed on the eggs.

The temperature of a sea turtle's nest can determine the sex of the babies. Warmer temperatures produce more females, while cooler temperatures produce more males.

Hatchlings emerge at night

In Belize, hatchling sea turtles emerge from their nests at night. This is because they are protected by the cover of darkness as they make their way down the beach to the sea. The female sea turtles also come onto land under the cover of night to lay their eggs.

The nesting process is an arduous one. After a long journey to land, the female sea turtle makes a long trek up the beach to lay her eggs. She chooses a well-protected area, above the high tide line, and begins the process of digging the nest. She will lay up to one hundred eggs that will incubate for 30 to 60 days before hatchlings emerge.

The incubation period is a precarious time for the eggs. They are vulnerable to hazardous conditions and predators such as wild dogs, raccoons, skunks, and birds. Human activity can also pose a threat to the eggs. It is important for humans to respect the turtles and turtle nests they may come across in Belize and give them the space they need to complete this critical stage of their life cycle.

Once the hatchlings emerge from their nests, they face a treacherous journey down the beach to the sea. Even after they reach the water, they are still not safe from predators. The journey from nest to ocean is a dangerous one, and not all hatchlings will survive.

Threats to eggs include dogs, raccoons, birds, and humans

Sea turtles in Belize face a variety of threats, including human activity, natural predators, and disease. While the country is known for its coral reef, the presence of endangered sea turtles is sometimes overlooked. Three types of turtles—Green, Hawksbill, and Loggerhead—nest in Belize, and are regularly found between the coast and the barrier reef. These turtles are drawn to the country due to its ideal feeding and nesting grounds.

Despite the protective measures in place, sea turtle eggs in Belize remain vulnerable to various threats, including dogs, raccoons, birds, and humans. Dogs, especially in packs, can wreak havoc on sea turtle nests, using their exceptional sense of smell to locate and dig up nests. They may consume both the eggs and the emerging hatchlings, and there are even accounts of them attacking adult turtles. Raccoons, too, pose a significant threat to sea turtle nests, as they are attracted to human trash left near beaches and have adapted well to human environments.

Birds also prey on sea turtle eggs, taking advantage of the turtles' vulnerability on land. Additionally, human activities such as the illegal harvest of eggs, the sale of turtles for meat and eggs, and the use of their shells as raw materials, further endanger the turtles' survival. While these practices are now illegal in Belize, the enforcement of regulations remains a challenge.

The combination of natural and human-induced threats puts the survival of sea turtles in Belize at risk. It is crucial to address these issues through stricter enforcement, public awareness, and the establishment of protected areas to ensure the long-term recovery of these endangered species.

Human activity is the greatest threat to sea turtles

Sea turtles in Belize face a variety of threats, both natural and human-induced. While natural threats include predators such as wild dogs, raccoons, skunks, and birds, the greatest threat to their survival comes from human activities.

Human activities have become an acute danger to sea turtles, and the increasing human population has exacerbated this problem. The primary threat is from fisheries, where sea turtles get accidentally entangled and drown in fishing gear such as longlines, gill nets, and trawls. They are also affected by the illegal trade and consumption of their meat, eggs, oil, cartilage, skin, and shells. The beautiful shells of hawksbill turtles, in particular, have been traded for centuries to make jewelry and luxury items, leading to a 90% decline in their population.

The construction of piers, sea walls, and tourist infrastructure, along with dredging, anchoring, and waste disposal, destroys their nesting habitats and disrupts their feeding grounds. Coastal development also brings artificial lighting, which discourages female sea turtles from nesting and causes hatchlings to become disoriented, wandering inland and often dying of dehydration or falling prey to predators.

Climate change is another significant threat, impacting the sex ratios of hatchlings, causing sea levels to rise and erode nesting beaches, increasing the likelihood of disease outbreaks, and intensifying extreme weather events that destroy their habitats.

In Belize, specifically, the development of the tourism industry poses the greatest threat to sea turtles. The building of piers, sea walls, and dredging for construction destroys their habitats. While there are conservation efforts and protected areas in place, such as the Ambergris Caye Master Plan, stricter enforcement of regulations and increased public awareness are necessary to ensure the survival of sea turtle populations in Belize.
