Green Sea Turtle in the New England Aquarium Has Been in Captivity Since 1970, and Is Believed to Be Around 80 Years Old (NEAQ 2013)
Species Status Assessment Class: Reptilia Family: Cheloniidae Scientific Name: Chelonia mydas Common Name: Green turtle Species synopsis: The green turtle is a marine turtle that was originally described by Linnaeus in 1758 as Testudo mydas. In 1868 Marie Firmin Bocourt named a new species of sea turtle Chelonia agassizii. It was later determined that these represented the same species, and the name became Chelonia mydas. In New York, the green turtle can be found from July – November, with individuals occasionally found cold-stunned in the winter months (Berry et al. 1997, Morreale and Standora 1998). Green turtles are sighted most frequently in association with sea grass beds off the eastern side of Long Island. They are observed with some regularity in the Peconic Estuary (Morreale and Standora 1998). Green turtles experienced a drastic decline throughout their range during the 19th and 20th centuries as a result of human exploitation and anthropogenic habitat degradation (NMFS and USFWS 1991). In recent years, some populations, including the Florida nesting population, have been experiencing some signs of increase (NMFS and USFWS 2007). Trends have not been analyzed in New York; a mark-recapture study performed in the state from 1987 – 1992 found that there seemed to be more green turtles at the end of the study period (Berry et al. 1997). However, changes in temperature have lead to an increase in the number of cold stunned green turtles in recent years (NMFS, Riverhead Foundation). Also, this year a record number of nests were observed at nesting beaches in Flordia (Mote Marine Laboratory 2013). 1 I. -

However, the impact of these parasites on sea turtle health is poorly understood due to biases in study populations and limited or missing data for some host species and regions, includ- ing the southeastern United States. We examined necropsy findings and parasitological data from 89 log- gerhead Caretta caretta and 59 green turtles Chelonia mydas that were found dead or moribund (i.e. stranded) in Florida (USA) and evaluated the role of spirorchiidiasis in the cause of death. -
AN INTRODUCTION to Texas Turtles
TEXAS PARKS AND WILDLIFE AN INTRODUCTION TO Texas Turtles Mark Klym An Introduction to Texas Turtles Turtle, tortoise or terrapin? Many people get confused by these terms, often using them interchangeably. Texas has a single species of tortoise, the Texas tortoise (Gopherus berlanderi) and a single species of terrapin, the diamondback terrapin (Malaclemys terrapin). All of the remaining 28 species of the order Testudines found in Texas are called “turtles,” although some like the box turtles (Terrapene spp.) are highly terrestrial others are found only in marine (saltwater) settings. In some countries such as Great Britain or Australia, these terms are very specific and relate to the habit or habitat of the animal; in North America they are denoted using these definitions. Turtle: an aquatic or semi-aquatic animal with webbed feet. Tortoise: a terrestrial animal with clubbed feet, domed shell and generally inhabiting warmer regions. Whatever we call them, these animals are a unique tie to a period of earth’s history all but lost in the living world. Turtles are some of the oldest reptilian species on the earth, virtually unchanged in 200 million years or more! These slow-moving, tooth less, egg-laying creatures date back to the dinosaurs and still retain traits they used An Introduction to Texas Turtles | 1 to survive then. Although many turtles spend most of their lives in water, they are air-breathing animals and must come to the surface to breathe. If they spend all this time in water, why do we see them on logs, rocks and the shoreline so often? Unlike birds and mammals, turtles are ectothermic, or cold- blooded, meaning they rely on the temperature around them to regulate their body temperature. -
Background on Sea Turtles
Background on Sea Turtles Five of the seven species of sea turtles call Virginia waters home between the months of April and November. All five species are listed on the U.S. List of Endangered and Threatened Wildlife and Plants and classified as either “Threatened” or “Endangered”. It is estimated that anywhere between five and ten thousand sea turtles enter the Chesapeake Bay during the spring and summer months. Of these the most common visitor is the loggerhead followed by the Kemp’s ridley, leatherback and green. The least common of the five species is the hawksbill. The Loggerhead is the largest hard-shelled sea turtle often reaching weights of 1000 lbs. However, the ones typically sighted in Virginia’s waters range in size from 50 to 300 lbs. The diet of the loggerhead is extensive including jellies, sponges, bivalves, gastropods, squid and shrimp. While visiting the Bay waters the loggerhead dines almost exclusively on horseshoe crabs. Virginia is the northern most nesting grounds for the loggerhead. Because the temperature of the nest dictates the sex of the turtle it is often thought that the few nests found in Virginia are producing predominately male offspring. Once the male turtles enter the water they will never return to land in their lifetime. Loggerheads are listed as a “Threatened” species. The Kemp’s ridley sea turtle is the second most frequent visitor in Virginia waters. It is the smallest of the species off Virginia’s coast reaching a maximum weight of just over 100 lbs. The specimens sited in Virginia are often less than 30 lbs. -

Throughout its restricted range, Dermatemys has been intensely harvested for its meat and eggs and sold in local markets. -

Turtles, All Marine Turtles, Have Been Documented Within the State’S Borders
Turtle Only four species of turtles, all marine turtles, have been documented within the state’s borders. Terrestrial and freshwater aquatic species of turtles do not occur in Alaska. Marine turtles are occasional visitors to Alaska’s Gulf Coast waters and are considered a natural part of the state’s marine ecosystem. Between 1960 and 2007 there were 19 reports of leatherback sea turtles (Dermochelys coriacea), the world’s largest turtle. There have been 15 reports of Green sea turtles (Chelonia mydas). The other two are extremely rare, there have been three reports of Olive ridley sea turtles (Lepidochelys olivacea) and two reports of loggerhead sea turtles (Caretta caretta). Currently, all four species are listed as threatened or endangered under the U.S. Endangered Species Act. Prior to 1993, Alaska marine turtle sightings were mostly of live leatherback sea turtles; since then most observations have been of green sea turtle carcasses. At present, it is not possible to determine if this change is related to changes in oceanographic conditions, perhaps as the result of global warming, or to changes in the overall population size and distribution of these species. General description: Marine turtles are large, tropical/subtropical, thoroughly aquatic reptiles whose forelimbs or flippers are specially modified for swimming and are considerably larger than their hind limbs. Movements on land are awkward. Except for occasional basking by both sexes and egg-laying by females, turtles rarely come ashore. Turtles are among the longest-lived vertebrates. Although their age is often exaggerated, they probably live 50 to 100 years. Of the five recognized species of marine turtles, four (including the green sea turtle) belong to the family Cheloniidae. -

Guillen Environmental Institute of Houston University of Houston – Clear Lake 2700 Bay Area Blvd. Houston, Texas, 77584 *[email protected] 8th Triennial Diamondback Terrapin Working Group Meeting Wilmington, NC; October 11-13, 2019 Abstract As critical saltmarsh habitat declines and severe weather events (hurricanes, drought, etc.) become more frequent, it is important for resource managers to understand how species of greatest conservation need are utilizing available habitat. In highly urbanized bays, such as Galveston Bay, available marsh habitat is limited or declining and Diamondback terrapin (Malaclemys terrapin) populations exist in more isolated areas than other populations along the Gulf and Atlantic coasts. To determine seasonality and site fidelity of an insular population of terrapin, an acoustic array was installed using Vemco acoustic receivers. From March 2009-April 2014, 39 terrapin (33 female; 6 male) were fitted with V13-1H transmitters. Transmitters were detected every year and, across all years, every month. Over 62 consecutive months of monitoring, 9 showed no detections (Jan 2010; Sep 2011, Nov 2012-Feb 2013; May 2013; Jan-Feb 2014), all correlated with major weather events. -
