What would happen if sea turtles went extinct?
If sea turtles went extinct, dune vegetation would lose a major source of nutrients and would not be as healthy and would not be strong enough to maintain the dunes, resulting in increased erosion. Once again, all parts of an ecosystem are important, if you lose one, the rest will eventually follow.
How do turtles benefit the world?
“Turtles are great scavengers, the garbage patrol of an area,” eating up dead fish from lakes and rivers, Gibbons says. “They do no harm and they do a lot of good.” Turtles also provide homes for a lot of critters. Burrows dug by gopher tortoises shelter over 350 species, including burrowing owls, rabbits, and bobcats.
Why is saving the turtles important?
Both of these grazing activities maintain species diversity and the natural balance of fragile marine ecosystems. If sea turtles go extinct, it will cause declines in all the species whose survival depends on healthy seagrass beds and coral reefs. That means that many marine species that humans harvest would be lost.
Are sea turtles friendly to humans?
Sea turtles are not aggressive unless they are in danger. However, becoming too close to them increases the risk of getting a painful bite.
What is a turtles purpose in the ecosystem?
Turtles and their eggs are important prey to a wide variety of predators. These reptiles graze, they dig burrows, they disperse seeds, they create and modify habitats, and they affect food webs and mineral cycling. Losing these animals can be disastrous, the review says.
Why are sea turtles amazing?
1. They're really ancient. The oldest known sea turtle fossil is at least 120 million years old, making sea turtles some of the oldest creatures on the planet. That means they shared the planet with dinosaurs which became extinct around 65 million years ago.
What role do sea turtles play in the food chain?
Sea turtles play a significant role in balancing the oceans' food chain. They feed on more than 200 taxa of vertebrates and invertebrates, including marine sponges, jellyfish, molluscs and crustaceans. Green turtles, for instance, help to maintain healthy seagrass beds, by grazing on it.

Why are sea turtles important?
Sea turtles are of great economic value. They are the assets of those countries who have them in their territory. Sea beaches are popular tourists spot. Every year lots of people travel throughout the beaches of the world. And the beauty of the sea beaches is its living beings. Without corals, fishes, turtles and other estuarine animals, sea beaches lose its beauty. And to keep the ecosystem of the sea working in a proper way, all living beings should be conserved.
How long have sea turtles been around?
Sea turtles have been living on this planet named Earth for more than 100 million years and they have travelled throughout the oceans of the world. They are one of the oldest species living on the earth. Their body structure is so much well designed that they have even survived the extinction which the dinosaurs failed to survive. But now human beings have become the greatest threat for the survival of this mighty creature. We have destroyed the harmony of nature and environment in such a way that sea turtles who have survived great extinctions are now on the brink of getting extinct. We can learn about the present condition of the earth's climate and environment by observing the present condition of the sea turtles.
What would happen if the green sea turtles went extinct?
Sea grass also needed to be cut short like lawn grass for its better growth. Sea beds provide the ground for breeding for many valuable sea animals like crustaceans, fish, shellfishes etc. If turtles get extinct, health of the sea bed will be deteriorated and sea grass will decline. As a result, animals living on grass will be lost and this will affect other big animals who live on small herbivorous animals. Eventually whole ecosystem will collapse resulting in the destruction of the living beings of the sea which is the source of beauty of the sea beaches. So tourists would not come to travel sea beaches and the countries whose economies depend on tourism will suffer in the long run.
Why do we need more vegetation in the dunes?
The more the nutrition the more vegetation grows in dunes. And as more vegetation grows, ecosystem of the beaches and dunes works properly. The vegetation also grabs the sands firmly in the beaches and prevents from being eroded. This saves the beauty of the sea beach. As the number of sea turtles is decreasing day by day, nutrition sources of dunes and beaches are also decreasing as a consequence. This will lead to the failure of the whole ecosystem and as a result the beach will lose its appeal to the tourists which will affect the economy of these countries severely.
Why are sea turtles important to humans?
Humans benefit from the presence of sea turtles because of the important role they fill in terrestrial and marine ecosystems. Stabilized sand dunes and barrier islands help to protect coastal communities from severe tropical systems and help to support ecotourism. Healthy marine ecosystems support commercial fisheries and provide opportunities for recreation. Despite these benefits, all species of turtles face an uncertain future due primarily to human activity.
Why are sea turtle nests marked?
Sea turtle nests are marked and monitored by park staff to protect future generations of sea turtles.
What do green turtles graze on?
In a marine ecosystem, green turtles graze on estuarine and nearshore seagrass beds, thereby maintaining and cultivating seagrass cover that provides crucial habitat for breeding and development grounds for many species of fish, shellfish, and crustaceans. Loggerheads increase the rate at which shells disintegrate and increase the rate of nutrient recycling in ocean bottom ecosystems. All turtles carry around barnacles, algae, and epibionts that are then consumed by other fish and shrimp. Finally, all turtles are indicator species or sentinel species, which means that their abundance, distribution, and health in the ecosystem are reflective of environmental conditions.
Why are turtles important?
Even in death, turtles are essential. Because of their long lifespans and high bone content, their bodies contain high concentrations of minerals like calcium. Herbivorous turtles like the gopher tortoise are important to the calcium cycle of an ecosystem, as they accumulate a high amount of the mineral in life and release it slowly in death.
How do turtles regulate energy?
Turtles also regulate the energy flow of a given environment. Turtles redistribute energy in multiple ways, such as by being a food source for predators. In addition to being prey themselves, their eggs are food for many animals. Sea turtles lay their eggs on land, but only 27% of the energy in those eggs actually returns to the ocean as hatchlings. The rest stays on land and provides energy to the organisms that dwell on it. Beach vegetation benefits from the minerals that are released by the breakdown of eggshells and the bodies of unfortunate hatchlings. This vegetation keeps erosion in check, and a decline in sea turtle population could result in a decline in the number of beaches.
Why is vegetation important to the beach?
Beach vegetation benefits from the minerals that are released by the breakdown of eggshells and the bodies of unfortunate hatchlings. This vegetation keeps erosion in check, and a decline in sea turtle population could result in a decline in the number of beaches. Turtles are also important consumers.
What are some animals that are worthy of protection?
Tigers, polar bears, rhinos, and pandas are all important animals that are worthy of protection, but so are more humble and unassuming animals like the turtle. By ignoring these animals, we reinforce a societal belief that these animals are either not in any danger or not worth protecting. By expanding awareness of the importance ...
Do sea turtles shape their ecosystems?
Even sea turtles can shape their ecosystems: loggerhead turtles have a unique foraging strategy that greatly increases the breakdown of mollusk shells and other sediment, which affects seagrass growth. Even in death, turtles are essential.
What are the effects of sea turtles?
1. Sea turtles, especially green sea turtles, are one of the very few animals to eat sea grass. Like normal lawn grass , sea grass needs to be constantly cut short to be healthy and help it grow across the sea floor rather than just getting longer grass blades.
What would happen if sea turtles went extinct?
If sea turtles went extinct, both the marine and beach/dune ecosystems would be negatively affected. And since humans utilize the marine ecosystem as a natural resource for food and since humans utilize the beach/dune system for a wide variety of activities, a negative impact to these ecosystems would negatively affect humans.
How many eggs do sea turtles lay?
Sea turtles use beaches and the lower dunes to nest and lay their eggs. Sea turtles lay around 100 eggs in a nest and lay between 3 and 7 nests during the summer nesting season. Along a 20 mile stretch of beach on the east coast of Florida sea turtles lay over 150,000 lbs of eggs in the sand.
Why are sea grass beds important?
This decline may be linked to the lower numbers of sea turtles. Sea grass beds are important because they provide breeding and developmental grounds for many species of fish, shellfish and crustaceans. Without sea grass beds, many marine species humans harvest would be lost, as would the lower levels of the food chain.
How long have sea turtles been around?
Much can be learned about the condition of the planet’s environment by looking at sea turtles. They have existed for over 100 million years, and they travel throughout the world’s oceans. Suddenly, however, they are struggling to survive — largely because of things people are doing to the planet’s oceans and beaches.
How does dune vegetation help the ecosystem?
Dune vegetation is able to grow and become stronger with the presence of nutrients from turtle eggs. As the dune vegetation grows stronger and healthier, the health of the entire beach/dune ecosystem becomes better. Stronger vegetation and root systems helps to hold the sand in the dunes and helps protect the beach from erosion. As the number of turtles declines, fewer eggs are laid in the beaches, providing less nutrients. If sea turtles went extinct, dune vegetation would lose a major source of nutrients and would not be as healthy and would not be strong enough to maintain the dunes, resulting in increased erosion. Once again, all parts of an ecosystem are important, if you lose one, the rest will eventually follow.
Why are sea turtles important?
As you might be able to see, without sea turtles, coastal and oceanic ecosystems would suffer; needing to beaches and adapt in order to continue regulating a variety of factors and stressors. Sea turtles help regulate these factors in a unique way; without them , there are a variety of problems that can occur. Protecting sea turtles protects the beach and ocean, and in the end, protects us!
Why do sea turtles die?
As sea turtles continue to face threats, seagrass beds have had trouble growing properly, and as a result, begin to die. As sea turtles face more threats, the animals that live in or depend on seagrass for food (like manatees) will be affected.
What are the animals that live in sea turtle shells?
Sea turtles also provide habitat for animals like barnacles or small crabs. These are called epibiota, and often attach to sea turtles’ shells due to their hard surface. Although it’s true that too many epibionts can be problematic for a lethargic or sick turtle, many healthy wild sea turtles will host at least one species of epibiota on their shell. As sea turtles travel through the sea, these epibiota often grow larger, live longer and can spread to new locations, adding to a wider dispersal of the animals.
What would happen if sea turtles went extinct?
If sea turtles were to become extinct, coral reefs would slowly but surely be outnumbered by sea sponges. Just like hawksbills keep sponges in check, leatherback sea turtles prey on jellyfish to keep those populations in check.
How do unhatched sea turtle eggs help the beach?
However, thanks to unhatched turtle eggs, plants can get enough nutrients from the decomposing eggs to grow deeper roots in the sand dunes. These roots help hold the sand in place and protect the beach from eroding. When animals like shorebirds eat unhatched sea turtle eggs, those nutrients return to the earth through the birds’ feces, helping spread nutrients around the dunes. This helps protect our beaches from erosion. With less sea turtles, there are fewer nutrients to help dune plants thrive, allowing for more beach erosion.
Why do green sea turtles graze on seagrass?
When green sea turtles regularly graze on seagrass, the blades gain more nutrients and can thrive, rather than become overgrown and end up decomposing.
How do roots help the beach?
These roots help hold the sand in place and protect the beach from eroding. When animals like shorebirds eat unhatched sea turtle eggs, those nutrients return to the earth through the birds’ feces , helping spread nutrients around the dunes. This helps protect our beaches from erosion.
Why is it important to protect sea turtles?
As sea turtle populations decline, so does their ability to fulfill vital functions in the ocean ecosystems. Hence, it’s time for us to protect sea turtles and rebuild their populations to healthy levels as a vital step in ensuring healthy and resilient oceans for the future.
Why do sea turtles raise their heads?
Similarly like we do when getting a massage, turtles expose their bodies, stretching their limbs and raising their heads to allow other fish to pick the treats off their shells. This activity not only feeds smaller organisms, but also benefits sea turtles. When their skin and shells are clean, they have lower resistance while swimming.
What are the creatures that live on the shells of sea turtles?
Epibionts call sea turtles home. Epibionts are creatures which attach themselves to solid surfaces in the ocean such as crabs, whales, sea turtles and even floating debris. Researchers have found that more than 100 different species of epibionts live on the shells of loggerhead turtles! By taking such an efficient ride, epibionts get distributed to further locations across the ocean, which increases their survival rates. Although, some of them actually harm their generous host, others come with benefits for sea turtles as well [3].
How do loggerhead turtles feed?
Loggerhead turtles have large powerful jaws that allow them to feed on a prey with hard shells. They crush the shells and discard the pieces. This activity helps increase the rate at which the shells disintegrate, which boosts the rate of nutrient recycling and keeps the ocean floor sediments balanced.
Why do sea turtles have a delivery boy?
Sea turtles function as a delivery boy for some fish and shrimp species. This is because they carry around barnacles, algae and epibionts. There are even special “cleaning stations” for sea turtles to visit, where they go to get their pampering treatment.
Why are sea turtles endangered?
They are an irreplaceable organism to achieve the balanced ecosystem functioning, and yet, the population of these gentle creatures is threatened by commercial fishing, loss of the nesting habitat, as well as , climate change.
How many species of sea turtles are there in the world?
There are 7 species of sea turtles that live in our oceans and 6 of those are classified as endangered or threatened by the International Union for the Conservation of Nature (IUCN).
Why are sea turtles important?
five reasons sea turtles are Really really important 1 Turtles help control their prey. For example, leatherbacks help manage the amount jellyfish in the ocean, hawksbills help reefs by eating sponges that compete with them for space. 2 Turtle nesting helps beaches. The nutrients left behind by eggs and hatchlings that don’t survive provide an important source for coastal vegetation. 3 Hatchlings are an important source of food for many animals. Birds, fish, mammals like raccoons and others rely on plentiful hatchlings to survive during nesting season. 4 They are important for coastal economies and native communities. Many places rely on turtle watching or diving for jobs and income and a number of indigenous communities revere sea turtles as part of their cultures. Plus there are emotional and psychological benefits to seeing a sea turtle in the wild. 5 Green turtles grazing on seagrass is an important way to keep seagrass beds healthy. And healthy seagrass benefits many species and stores carbon.
How do sea turtles help the environment?
Sea turtles also have a positive influence out of the water. Nesting sea turtles help beaches by depositing their eggs in the sand. Eggshells and unhatched eggs left behind provide important nutrients that nourish dune vegetation such as beach grasses, which stabilize dunes and help to prevent coastal erosion.
WHAT IS SEE TURTLES?
We're a non-profit organization that protects sea turtles through conservation travel and volunteer tours, our Billion Baby Turtles, Too Rare To Wear, & Sea Turtles & Plastic programs, our education programs, and by promoting inclusivity in the sea turtle community. Our award-winning programs help save sea turtle hatchlings on important nesting beaches around the world, work with the tourism industry to end the turtleshell trade, and get plastic out of sea turtle habitats.

What do leatherback sea turtles eat?
Leatherback sea turtles specialize in eating jellyfish which keeps jellyfish populations in check. If leatherbacks were to disappear, jellyfish populations would explode. Jellyfish prey upon larval fish so without leatherbacks; without these larval fish there would be no fish in the sea! Again, it’s all about balance.
Why are turtles important to the environment?
Turtle nesting helps beaches. The nutrients left behind by eggs and hatchlings that don’t survive provide an important source for coastal vegetation . Hatchlings are an important source of food for many animals. Birds, fish, mammals like raccoons and others rely on plentiful hatchlings to survive during nesting season.
What do green sea turtles eat?
Adult green sea turtles primarily eat sea grasses, acting as aquatic lawnmowers which help keep seagrass beds healthy (like mowing your lawn!). Seagrass beds which are found in shallow marine waters, provide habitat, food, and protected nursery areas for many fish species, enabling them to take shelter from predators until they are larger.
What are the predators of sea turtles?
Hatchlings are prey for birds, crabs, land mammals, and fish. Adult sea turtles are prey for apex predators like sharks and orcas. On some beaches in Costa Rica, adult female sea turtles are even prey for jaguars that prowl nesting beaches at night, ...
