Today, there are seven sea turtles that exist in the ocean. The term “sea turtle” may classify turtles to sound the same, but all seven turtles are different from one another.

When people think of sea turtles, they often envision the green sea turtle. These turtles weigh about 400 pounds and are 5.5 feet in length. They mostly feed on sea grass and algae. In fact, the pigment from their green diet colors their fat, which gives them their label. Green sea turtles are deep divers and can stay under the water for up to five hours. Females mate every two to four years and populations have dropped up to 65 percent over the last 100 to 150 years.

Kemp’s Ridley Sea TurtleKempRidley copyThis turtle is one of the smallest turtles in the world. They weigh about 100 pounds and are 2.5 to 3 feet in length. They are grey and green in color and primarily reside in the Gulf of Mexico, Florida and Mediterranean waters. Their diet includes mollusks, jellyfish, crabs and small fish. A mature age is 10 to 20 years old and they can live up to 50 years.

Hawksbill Turtle


The hawksbill turtle is distinguished by its heart-shaped shell. As the turtle ages, the heart lengthens and the hawksbill grows two pairs of claws on the front feet and mouth similar to a bird’s beak. Hawksbills reside in tropical Pacific and Atlantic waters and desire rocky and shallow areas. They primarily consume sponges along with jellyfish, mollusks, crustaceans and small fish.

Leatherback TurtleLeatherback_turtle_nesting_on_a_beach_in_Grande_Riviere copyThe leatherback is the “big boy” and can weigh up to 2,000 pounds and grows to seven and one-half feet in length. Leatherbacks are the fourth largest reptile, only behind three species of crocodiles. Leatherbacks cruise the entire world, but are regularly found in Florida, St. Croix and Puerto Rican waters. They have a large appetite and can travel hundreds of miles in search of energy from jellyfish. Unfortunately, jellyfish are rough on their digestion, which causes an intestinal block. When food is not available, they will eat plastic bags, as it resembles a jellyfish.
