Leatherback:
- Scientific name: Dermochelys coriacea
- Family: Dermochelyidae
- Description: Leatherback sea turtles are the largest species of sea turtle and are unique in having a leathery carapace rather than a hard shell like other sea turtles. They are the most migratory sea turtle species and can travel long distances across oceans.
Loggerhead:
- Scientific name: Caretta caretta
- Family: Cheloniidae
- Description: Loggerhead sea turtles have a reddish-brown carapace and a large head with a powerful jaw. They are named after their large head and robust jaw structure. Loggerhead sea turtles inhabit various temperate and tropical waters around the world.
Both leatherback and loggerhead turtles face conservation challenges due to threats such as habitat loss, bycatch in fishing gear, plastic pollution, and illegal trade. These species are considered vulnerable to extinction by the International Union for Conservation of Nature (IUCN) and require protection measures to ensure their survival.
