QUIZ

question 2/9

Which is the largest sea turtle in the ocean?

The Leatherback (Dermochelys coriacea)

The Loggerhead (Caretta caretta)

QUIZ

CORRECT

Explanation: Leatherbacks are the biggest sea turtles known today. Adult leatherbacks measure 140-180+ cm (4.5 to 6+ ft) in length and weigh between 300-640 kg. Leatherback hatchlings are approximately 50mm long and weigh 40-50g. The largest leatherback ever recorded almost 3m (9 ft) in length, and weighed 914 kg

QUIZ

question 3/9

Sea turtles spend most of their lives in the sea

False

True

QUIZ

CORRECT

Explanation: Adult female turtles return to the same area they hatched on to nest with remarkable precision. They then return to the sea, leaving the eggs to hatch in the nest. Hatchlings never get to meet their parents!

QUIZ

question 4/9

Sea turtles’ are exceptional long-distance migrator species. They have great orientation and navigation skills. It is a mystery that scientists only begin to unveil. How do sea turtles navigate?

Using using the Earth’s magnetic field

Using ocean currents, waves and tides

QUIZ

CORRECT

Explanation: Sea turtles use the earth’s magnetic field to migrate precisely and consistently across vast distances in the ocean. Each oceanic region has a unique magnetic field associated with it. Turtles detect the subtle differences in the magnetic field which is unique for each oceanic region.

QUIZ

question 5/9

Sea turtles have many natural predators throughout their life circle.

True

False

QUIZ

CORRECT

Sea turtles don’t have it easy. They have countless natural predators before they even hatch and throughout their lives. In some parts of the world, adult female turtles face jaguars during nesting, and saltwater crocodiles in inshore waters. Nests are being raided by raccoons, foxes, dogs, ants, several species of crabs, snakes, dingoes, jackals, lizards; or many forms of microbes, insects, mites, and more. When crawling from their nest to the sea, hatchlings are vulnerable to mammals, birds, and crabs. In coastal waters they get eaten by large bony fish, sharks and sea birds. In adulthood, they have large bodies, powerful jaws, and hard shells. Their predators at sea are mainly large sharks (especially tiger sharks).

QUIZ

QUESTION 6/9

There are 7 species of sea turtles known to scientists today. How many are at risk?

QUIZ

CORRECT

Explanation: Sea turtles have been around for more than 110 million years. However, 6 out of the 7 species of these ancient mariners; they are classified as either vulnerable, endangered, or critically endangered. These six species are: Loggerheads, Greens, Leatherbacks, Hawksbill, Kemp's Ridley, and Olive Ridley. There is simply a lack of data on Flatbacks to assess how much at risk they are! Sea turtles have seen the dinosaurs go extinct. However, today they are threatened with extinction. Specialists have identified five major threats to sea turtles worldwide: direct take, coastal development, fisheries bycatch, pollution and pathogens, and climate change.

QUIZ

QUESTION 7/9

Sea turtles exhibit temperature-dependent sex determination. One of the impacts of climate change on sea turtles is that the rise in global temperatures will result in:

higher the ratio of male turtles

higher the ratio of female turtles

QUIZ

CORRECT

Explanation: We can’t fully estimate the threat to sea turtles from climate change. Scientists do know that the gender of sea turtles is determined by the temperature of the sand in which the eggs are laid. Warmer temperatures produce female hatchlings, and cooler temperatures produce male hatchlings. There is also an increased likelihood of disease outbreaks. The increased frequency of extreme weather events destroys nesting beaches and coral reefs.

QUIZ

QUESTION 8/9

Marine litter harm sea turtles in many ways. Plastic pollution, including ghost fishing gear, may:

be a great source of food for sea turtles and help guide them to the shore

injure sea turtles through ingestion and result to their entanglement

QUIZ

CORRECT

Explanation: Marine litter entanglement slows down sea turtles, making them more vulnerable to their predators. Entanglement also causes injuries, suffering, and infections. Buoyancy is affected, and sea turtles are prevented from diving to feed, and they might be at a higher risk from vessel strikes. On nesting beaches, hatchlings are prevented from reaching the sea quickly and become easy prey to their natural predators. When trapped in litter, they become dehydrated in the heat and perish. Plastic ingestion results in injuries, starvation, and death.

next

QUIZ

QUESTION 9/9

What was the cause of death for the largest Leatherback ever recorded?

Poaching

Drowning

QUIZ

CORRECT

Explanation: The largest leatherback ever recorded was approximately 100 years old. The cause of death was drowning after being trapped by fishing lines! The turtle was washed ashore on Harlech beach, Gwynedd, in September 1988. It is on display at the National Museum in Cardiff.

Who we are

Who are we - Healthy Seas

Healthy Seas is a foundation committed to marine conservation and removing marine litter, especially fishing nets, to foster healthier seas and repurpose waste into innovative products. Within our comprehensive approach to ocean conservation, an integral component involves educational outreach.

In our commitment to education, we actively engage children of various ages through captivating presentations and hands-on activities focused on marine conservation and the impact of marine litter. Additionally, we provide an immersive virtual reality experience, allowing young minds to explore as divers the underwater world and understand the importance of preserving the seas for future generations. Beyond education, our pillars encompass cleanups and prevention. In collaboration with volunteer divers and fishermen, we have successfully removed over 991 tons of waste globally. Our reach spans from the US to Korea, involving 150 partners and 550 dedicated volunteers. www.healthyseas.org
