Sea turtles are among the most iconic marine creatures, captivating the imagination of people worldwide. With their graceful movements and ancient lineage spanning over 100 million years, sea turtles are a vital part of ocean ecosystems. However, they face severe threats that jeopardise their survival.
Fascinating Facts About Sea Turtles
- There are seven species of sea turtles: green, loggerhead, leatherback, hawksbill, olive ridley, Kemp’s ridley, and flatback.
- Sea turtles can hold their breath underwater for hours, depending on their activity level.
- They play a critical role in maintaining marine ecosystems by grazing on seagrass, which promotes healthy ocean beds.
The Plight of Sea Turtles
Sea turtle populations have declined significantly due to human activities. Six out of seven species are currently listed as vulnerable, endangered, or critically endangered. Their plight is caused by a combination of threats:
- Plastic Pollution: Turtles often mistake plastic bags and other debris for food, leading to injury or death.
- Habitat Loss: Coastal development disrupts nesting sites, reducing their chances of successful reproduction.
- Bycatch: Thousands of turtles are accidentally caught in fishing gear each year, causing injury or drowning.
- Climate Change: Rising sea levels and warming sands affect nesting beaches and turtle hatchlings, as the sand temperature determines their sex.
Efforts to Save Sea Turtles
Conservation efforts focus on protecting nesting beaches, reducing bycatch through sustainable fishing methods, and raising awareness about pollution. Organisations worldwide are working tirelessly to restore sea turtle populations, and individuals can contribute by reducing plastic use and supporting eco-tourism initiatives.
