Fun Facts About Sea Turtles

Sea Turtles Are Air-Breathing Reptiles

While they live the vast majority of their lives in saltwater, sea turtles can hold their breath for up to two hours when resting. In fact, the only time sea turtles come on land is during nesting season. Female sea turtles will walk ashore during nesting season to lay up to 100 eggs at a time. Nesting season spans from March to October. 

Baby Sea Turtles Are About Three Inches Long When They Hatch 

Between 50 and 60 days after their eggs are laid, baby sea turtles hatch adorably small. They exercise their instincts fresh out of their eggs with a sprint toward the ocean to begin their lives of saltwater dwelling. The sight of hundreds of baby Key West sea turtles storming the shores in an instinctual, precious stampede is something to cherish forever. 

Sea Turtles Feed on Jellyfish 

A sea turtle’s diet varies from species to species, with most of them enjoying the occasional jellyfish. This makes ocean pollution especially dangerous for Key West sea turtles, as they often mistake plastic bags for jellyfish. Things like bags, cups and soda rings discarded in the ocean pose threats to the sea turtles, and can prove fatal if ingested. When in Key West, be sure to do your part to help Key West sea turtles.

Sea Turtles Have Long Life Spans 

Loggerheads, one of the more common Key West sea turtles, are known to live up to 70 years. They can also grow to be much larger than people assume, some weighing up to 1,000 pounds! The best indicator of a sea turtle’s age is its size. 

Different Types of Key West Sea Turtles

In total, there are seven different species of sea turtles. The Key West sea turtle population is mainly comprised of five of the seven — loggerheads, green sea turtles, hawksbill, Kemp’s ridley and leatherback — each displaying unique characteristics that add to their overall intrigue. These fascinating creatures of the sea have made Key West one of the best turtle-watching destinations in the United States. 


Scientific name Caretta caretta, the loggerhead sea turtle is named for its notably large head. These Key West sea turtles are typically 2.5 to 3.5 feet long in size and weigh anywhere from 155 to 375 pounds. Loggerheads have exceptionally strong jaws, which play a large role in their mainly carnivorous diet. These turtles feed mostly on shellfish that live on the ocean floor, such as horseshoe crabs, clams and mussels. They have no problem crushing the shellfish with their strong jaws. Female loggerheads are known to lay three to six nests over the season, each nest containing anywhere between 100 and 126 eggs. Today, the loggerhead faces a number of threats to survival, such as loss of nesting habitats, pollution and human disturbances that create disorientation among hatchlings making their way to the ocean at birth. Loggerheads are classified as a threatened species of sea turtle, likely to become endangered.

Green Sea Turtles

Scientific name Chelonia mydas, green sea turtles are named for the green color of the fat under their shells. These Key West sea turtles are distinguishable from other species by the single pair of scales in front of their eyes, whereas other species have two pairs. The green sea turtle ranges from 3 to 4 feet in length and can weigh anywhere between 240 and 420 pounds. The diet of the green sea turtle changes over the course of its life, beginning in omnivorous territory. However, as these turtles mature, their diet shifts to strictly herbivorous, and they are the only turtles to do so. Their finely serrated jaws assist them in tearing vegetation such as seagrass and algae. Female green sea turtles lay three to five nests every two years, each nest containing an average of 115 eggs. Today, incidental catch by commercial shrimp boats have proven to be one of the greatest threats to the survival of these Key West sea turtles. They are classified as threatened and likely to become endangered. 

Hawksbill Sea Turtles

Scientific name Eretmochelys imbricata, the hawksbill sea turtle gets its name from its narrow head and hawk-like beak. This anatomical feature allows the hawksbill to feed from crevices in coral reefs. The hawksbill’s diet consists of sponges, anemones, squid and shrimp. This Key west sea turtle can range from 2.5 to 3 feet in length and weigh between 101 and 154 pounds. Female hawksbills nest in intervals of two to four years and build three to six nests per season. Each nest has an average of 160 eggs. Hawksbill turtles can usually be found around coastal reefs, rocky areas, estuaries and lagoons, making them the perfect Key West sea turtle. These beautiful creatures are classified as endangered, and are constantly threatened by harvesting of their prized shell. 

Kemp’s Ridley Sea Turtles

Scientific name Lepidochelys kempil, Kemp’s ridley are named after scientist Richard Kemp, who is credited with the discovery of the species. Relatively small compared to other Key West sea turtles, Kemp’s ridley measure around 2 feet in length and weigh between 70 and 108 pounds. These Key West sea turtles are known to nest more frequently than other species of turtles, making the trip to shore every one to three years on average. Kemp’s ridley partake in mass synchronized nestings called arribadas and nest two to three times a season. These nests contain an average of 110 eggs each. With powerful jaws, Kemp’s ridley feed on crabs, clams, mussels and shrimp, as well as fish, sea urchins and jellyfish. This gracious turtle is listed as endangered and faces major threats from human activity, including hunting and collection of eggs. 

Leatherback Sea Turtles 

Scientific name Dermochelys coriacea, the leatherback is the largest sea turtle and the largest living reptile in the entire world! These sea turtles can grow to be 8 feet in length and weigh up to 2,000 pounds. They are the only sea turtle that lacks a hard, outer shell and is most known for its leathery black or brown skin. These characteristics are what gave the leatherback sea turtle its name! Leatherback sea turtles feed mostly on soft-bodied animals, such as jellyfish, consuming nearly their own body weight in prey every day. The female leatherbacks are known to lay 5 to 7 nests over the season with around 100 billiard ball sized eggs in each. These eggs take about 2 months to hatch where they will then make their way to the sea! Only around 6 percent of hatchlings survive their first year. The leatherback sea turtle is listed as endangered under the Endangered Species Act.
