Green sea turtles and loggerhead sea turtles live along the beaches of the Atlantic and the Pacific oceans. Green sea turtles are endangered, meaning there are not many of them left in the world. Loggerheads are listed as threatened. This means loggerhead sea turtles are on their way to becoming endangered. Grass, algae, and other plants are what green sea turtles eat. Because of this, they are herbivores. Loggerhead sea turtles like to eat horseshoe crabs, clams, and mussels. Because they eat meat, loggerheads are carnivorous animals. Both the loggerhead and green sea turtles tend to stay close to the coastline.
