10 Things to Know About Sea Turtles

Posted On June 16, 2016 by

This blog was written by Roger Di Silvestro, a field correspondent for Ocean Conservancy.

Sea turtles are among the world’s most ancient vertebrates. When on land, they look cumbersome and awkward, their powerful front flippers struggling to pull their weight across ocean shores. But in the water, where they spend most of their lives, sea turtles fly through the water much as birds soar through the sky. Their flippers become wings, their disk-shaped bodies cut through the sea like torpedoes.

Sea turtles remain one of nature’s great mysteries—scientists have only begun to discover secrets of sea turtle life. Here are ten things science can tell you about these marine animals.

Ocean Plastic Pollution: Groundhog Day, But This Time with Sea Turtles

Posted On September 15, 2015 by

I got a kick out of Groundhog Day, the comedy starring Bill Murray and Andie MacDowell that was released in 1993. With Murray waking each day to relive Groundhog Day alongside Punxsutawney Phil and his co-anchor, the movie was lighthearted and fun. But the science of ocean plastic pollution is starting to feel a lot like Groundhog Day. And the storyline is becoming much more troubling with each new publication.

This week a new study in the peer-reviewed journal Global Change Biology calculates that over half of the world’s sea turtles have ingested plastic; this follows on the heels of a publication last month by some of the same scientists that predicted that nearly all of the world’s seabirds would be contaminated with plastics by 2050 unless action is taken soon. With each new publication, the case for a global strategy to stem the tide of plastics into the world’s oceans becomes ever more vital.

Interview: Dr. Blair Witherington on Oil’s Impact on Turtles in the Gulf of Mexico

(This blog is part of a series of interviews with scientists who are championing marine research in the Gulf of Mexico.)

A research scientist with more than 24 years of experience in sea turtle biology and conservation, Dr. Blair Witherington has worked with the Florida Fish and Wildlife Conservation Commission’s Fish and Wildlife Research Institute since 1992. He is also an adjunct assistant professor, department of zoology, University of Florida; served as president of the 20th International Sea Turtle Symposium; and is vice chair of the Northwest Atlantic region of the Marine Turtle Specialist Group of the International Union for Conservation of Nature. He has authored or contributed to more than 40 scientific articles, monographs and book chapters. In addition, he has written five books on sea turtles and other natural history subjects.

The BP Deepwater Horizon oil disaster had an immediate and particularly harmful effect on early juvenile sea turtles in the Gulf of Mexico. The worst marine oil spill in history also served to highlight a compelling need for assessments of open-sea habitats – research critically lacking in 2010, yet essential for conservation efforts and restoration planning.
