"Fenway" - an endangered Kemps ridley sea turtle rescued last fall on Cape Cod - flew out of Logan Airport Wednesday, April 20, 2005 for the New Orleans Aquarium and eventual release.
 The turtle was picked up by a veterinarian from the Audubon Aquarium of the Americas. The sea turtle will acclimate at the Louisiana Marine Mammal and Sea Turtle Rescue Program at the aquarium for about one month, then will be released into the Gulf of Mexico with a tracking satellite tag.
Fenway has spent the last two and one-half months recuperating at the Marine Animal Rehabilitation Center (MARC) at the University of New England's Marine Education and Research Center.
The endangered animal was rescued last fall by volunteers of the Wellfleet Audubon Sanctuary from freezing in Cape Cod's Wellfleet Bay, where the turtles stop during their long northerly travels, seduced by the bay's warm summer weather.
The turtle was named "Fenway" because he was the first sea turtle to arrive at the New England Aquarium for rehabilitation after the Red Sox won the World Series.
Background
Turtles around Cape Cod get stranded when the water turns cold quickly in the fall. The"cold-stunned" reptiles float to the top of the water and wash up onto the Cape's beaches. There they are transported to the New England Aquarium, which distributes them to rehab centers across the country.
UNE's Marine Animal Rehabilitation Center is the only facility in Northern New England licensed by the National Marine Fisheries Service to rehabilitate sea turtles. Fenway is the first turtle to come to UNE for rehabilitation.
To accommodate these animals, the Center had to install $22,000 of special equipment in one of its rehab pool rooms. The equipment includes two free-standing tanks, an ozone machine, and assorted heaters, filters and pumps. Funds for this equipment came from three donors: Dr. Owen Pickus and his wife, Dr. Geraldine Ollila-Pickus (the sea turtle rehab suite is named for their children, Gregory, Joshua and Ellie Pickus), the Maine Community Foundation and the Bernice Barbour Foundation.
Sea Turtles Stats
Sea turtles are large air-breathing reptiles that inhabit warm waters of the world's oceans, bays and estuaries. They are similar to tortoises and freshwater turtles, except that their legs are actually flippers that aid them in swimming.
Species of sea turtles range in size, shape and color. The olive ridley is usually less than 100 pounds, while the leatherback ranges from 650 to 1,300 pounds.
Sea turtles are closely related to ancient species dating back 130-150 million years to the Cretaceous Period.
Sea turtle shells consist of an upper part (carapace) and a lower section (plastron). Hard scales (or scutes) cover all but the leatherback. Sea turtles are air breathers, but are capable of holding their breath for quite some time. Their streamlined bodies and large flippers make them remarkably adapted to life at sea.
Sea turtles lack teeth, but their jaws have modified beaks, particularly suited to their feeding habits, which for most species include a variety of crustaceans, such as crabs, shrimp, and lobsters. Leatherbacks, however, feed chiefly on jellyfish.
Like other reptiles, sea turtles are cold-blooded, meaning their body temperature depends upon their surroundings. In the Atlantic, this necessitates that the turtles must migrate southward as northern waters cool off in the fall. Unfortunately, some individual turtles wait too long and become stranded in the northern waters and must be rescued.
There are five species of sea turtle in the North Atlantic Ocean - hawksbill, loggerhead, Kemp's ridley, green and leatherback. In the eastern United States sea turtles are found mainly along the southern and Mid-Atlantic coasts, Gulf of Mexico and in the Caribbean Sea. During the summer months when the Gulf Stream carries warm water north as far as Canada, sea turtles roam as far north as Cape Cod near the shore, while the leatherback ranges even further north.
Life Cycle
The life cycle for sea turtles begins in the spring and early summer as the males and females mate in the waters near the nesting beaches. The females come ashore, excavate holes 20-30 inches deep usually in the upper beach near the base of the dunes. They then deposit 80-200 ping-pong ball-sized eggs into the holes. Females may return to the nesting beach to lay up to 10 clutches of eggs in a season (except the Kemp's Ridley).
The eggs incubate in the hot sand for about two months before the tiny hatchlings break through the shell of the egg, usually at night, and scramble out of the nest to head for the water. These hatchlings are prey to many predators, however, and many are snatched up by ghost crabs, dogs, foxes, raccoons, opossums and gulls before they make it to the water. Once at sea, others are lost to predators such as fish and seabirds. It is estimated that less than 1 percent of the hatchlings live to maturity.
Researchers believe that baby turtles spend their earliest years floating around the sea in giant beds of sargasso weeds, where they do little more than eat and grow. Once turtles reach dinner-plate size, they appear at feeding grounds in nearshore waters. They grow slowly and take between 15 and 50 years to reach reproductive maturity, depending on the species. There is no way to determine the age of a sea turtle from its physical appearance. It is theorized that some species can live over 100 years.
Endangered or Threatened Species
Hunting, fishing, development and pollution have seriously reduced sea turtle populations. Development in coastal areas have greatly reduced natural nesting habitats. Capture of adult turtles for eggs, meat, leather, and tortoise shell has decreased breeding populations. Incidental capture of adults in fishing nets and shrimp trawls has brought one species, the Kemp's Ridley (Lepidochelys kempi), right to the brink of extinction. For these reasons all species of sea turtle are protected under federal endangered and threatened species legislation.
