What Species of Sea Turtles Are Endangered?
Sea turtles are some of the most majestic and ancient creatures on our planet. These marine reptiles have been swimming in the world’s oceans for over 100 million years. Unfortunately, many sea turtle species are now facing extinction due to various human-induced threats. In this article, we will discuss the different species of sea turtles that are endangered and the reasons why they are at risk.
The Seven Species of Sea Turtles
There are seven species of sea turtles that can be found worldwide, and six of these species are currently listed as endangered or vulnerable by the International Union for Conservation of Nature (IUCN). These species include:
- Leatherback Sea Turtle (Dermochelys coriacea)
- Green Sea Turtle (Chelonia mydas)
- Hawksbill Sea Turtle (Eretmochelys imbricata)
- Loggerhead Sea Turtle (Caretta caretta)
- Olive Ridley Sea Turtle (Lepidochelys olivacea)
- Kemp’s Ridley Sea Turtle (Lepidochelys kempii)
- Flatback Sea Turtle (Natator depressus)
Leatherback Sea Turtle
The Leatherback Sea Turtle is the largest of all sea turtle species, and it can weigh up to 2,000 pounds. These turtles have a unique appearance, with a leathery, flexible shell instead of a hard, bony one. Leatherback Sea Turtles are found in all the world’s oceans, and they migrate long distances to feed and nest. Unfortunately, they are also the most endangered sea turtle species, with a global population decline of over 90% in the last century.
The primary threats to Leatherback Sea Turtles are bycatch, the incidental capture of turtles in fishing gear, and the loss of nesting habitats due to coastal development and climate change. Plastic pollution is also a significant threat, as Leatherback Sea Turtles often mistake plastic bags for jellyfish, their primary food source.
Green Sea Turtle
Green Sea Turtles are named for the greenish color of their fat, which comes from their diet of seagrasses and algae. They are found in tropical and subtropical waters worldwide and are known for their gentle demeanor and graceful movements. Green Sea Turtles are listed as endangered due to a variety of threats, including bycatch, habitat loss, and climate change.
One of the most significant threats to Green Sea Turtles is the loss of nesting habitats due to coastal development. As human populations continue to grow, coastal areas are being developed for housing, tourism, and other uses, which can destroy or disturb nesting sites. Climate change is also a significant threat, as rising sea levels can flood nesting beaches and alter the temperature of sand, which can affect the sex of hatchlings.
Hawksbill Sea Turtle
Hawksbill Sea Turtles are known for their distinctive, hawk-like beaks, which they use to feed on sponges and other invertebrates. They have a beautiful, mottled shell that is highly prized for use in jewelry and decorative items.
