What are sea turtles named after?

What’s in a name? When it comes to sea turtles, it turns out, a pretty distinguishing trait.

“The animal kingdom is filled with plenty of common names, which may have been coined for a number of reasons, but could ultimately be considered misleading,” Sanibel-Captiva Conservation Foundation sea turtle biologist Jack Brzoza said.

Think red panda — reddish in color, sure, but not a panda (they are more closely related to raccoons and weasels). Or horned toads — horned? Yes. Toad? No. This animal is actually a lizard.

“When it comes to sea turtles however, their common names tend to be very fitting and characteristically accurate,” he said.

The SCCF provided the following of the different species:

– LOGGERHEAD

Loggerheads are named for their large, “blocky” heads that house powerful, prey-crushing jaws. Compared to the other species, they have a much larger head in proportion to the rest of their body. The loggerhead shrike is a bird that shares the “blockhead” moniker due to its large head-to-body ratio.

– LEATHERBACK

Leatherbacks do not have a hard, bony keratinous shell like the other six sea turtle species. Rather, leathery skin (in appearance and texture) covers connective tissue and small interlocking dermal bones.

– HAWKSBILL

The hawksbill turtle has a very pronounced, slightly curved and narrowed sharp beak, resembling those of birds of prey.

– FLATBACK

Flatbacks are named for their smooth and flattened carapace. They lack the dome-like appearance seen with the other sea turtle species.

– KEMP’S RIDLEY

Kemp’s ridleys are named after Richard Kemp, a Key West native among the first to describe the turtles. The “ridley” portion is not as clear, but may be in reference to the word “riddle,” on account of the many unknowns surrounding these turtles when first discovered — were they hybrid turtles, where did they nest, why did they sometimes nest en masse?

– OLIVE RIDLEY

“Olive” inis in reference to the olive-green color of an olive ridley’s shell. It shares the latter half of its common name with the Kemp’s ridley — they are in the only genus of sea turtles with two surviving species.

– GREEN TURTLE

At first glance, this name may seem like an exception. At all life stages, green turtles do not display any strikingly green coloration on their shell, scales, or skin. However, their internal fat has a green hue due to their largely herbivorous diets.

The majority of the sea turtle nests on Sanibel and Captiva are laid by loggerheads. Green sea turtles nest less frequently on the beaches, and very rarely is a leatherback or Kemp’s ridley nest seen.
