  • Phylum: Within the animal kingdom, sea turtles belong to the phylum chordata. This phylum includes animals with a notochord, a dorsal nerve cord, and gill slits at some point in their development.
  • Class: Sea turtles fall under the class reptilia. Reptiles are cold-blooded vertebrates that have scaly skin, lay eggs, and breathe air. They include lizards, snakes, and crocodiles, among others.
  • Order: Sea turtles belong to the order testudines, commonly known as turtles or tortoises. This order includes both land-dwelling and aquatic species.

Defining Reptiles And Amphibians:

Reptiles and amphibians are both cold-blooded vertebrates, but they have distinct characteristics:

Reptiles:

  • Have dry, scaly skin that helps prevent water loss.
  • Breathe predominantly through lungs.
  • Lay shelled eggs on land.
  • Most reptiles live primarily on land.
  • Reptiles include snakes, lizards, and turtles.

Amphibians:

  • Have thin, moist skin that allows for gas exchange.
  • Have a two-stage life cycle, starting as aquatic larvae (e.g., tadpoles) and then transforming into adults.
  • Typically lay soft, gelatinous eggs in water.
  • Most amphibians live in or near water.
  • Amphibians include frogs, toads, and salamanders.

Based on these characteristics, sea turtles fall under the category of reptiles, not amphibians. They have scaly skin, breathe air, and lay eggs on land, making them more closely related to other reptiles like lizards and snakes.
