A biphasic navigational strategy in loggerhead sea turtles [PDF]

Scientific Reports, 2020
AbstractThe homing journeys of nine loggerhead turtles translocated from their nesting beach to offshore release sites, were reconstructed through Argos and GPS telemetry while their water-related orientation was simultaneously recorded at high temporal resolution by multi-sensor data loggers featuring a three-axis magnetic sensor.

Barnacle Epibiosis on Sea Turtles in Korea: A West Pacific Region With Low Occurrence and Intensity of Chelonibia testudinaria (Cirripedia: Chelonibiidae)

Frontiers in Ecology and Evolution, 2022
Loggerhead and green turtles inhabit all oceans except the polar regions. External surfaces of sea turtles are often colonized by epibiotic chelonibiid barnacles.

Fishhook Lesions in Loggerhead Sea Turtles [PDF]

Journal of Wildlife Diseases, 2007
This study describes four cases of loggerhead sea turtles with fishhooks in the gastrointestinal tract. Two dead turtles with a hook in the esophagus had local fibrosis with an invagination of the keratinized stratified squamous epithelium surrounding the hook, isolating it from the subjacent stroma, one had a hook in the cloaca which was expelled ...

A Guide to Nesting Sea Turtles in Florida

EDIS, 2021
Florida’s coastline provides critical habitat for sea turtle nesting, as it has for millions of years. Throughout the state, three of the seven species of sea turtles in the world have significant nesting populations.

Perception of airborne odors by loggerhead sea turtles [PDF]

Journal of Experimental Biology, 2009
SUMMARY Sea turtles are known to detect chemical cues, but in contrast to most marine animals, turtles surface to breathe and thus potentially have access to olfactory cues both in air and in water. To determine whether sea turtles can detect airborne chemical cues, captive loggerhead turtles (Caretta caretta) were placed into a circular,

Cayman Islands Sea Turtle Nesting Population Increases Over 22 Years of Monitoring

Frontiers in Marine Science, 2021
Given differing trajectories of sea turtle populations worldwide, there is a need to assess and report long-term population trends and determine which conservation strategies are effective.

PROPOFOL ANESTHESIA IN LOGGERHEAD (CARETTA CARETTA) SEA TURTLES [PDF]

Journal of Wildlife Diseases, 2008
Rapid, safe, and effective methods of anesthetic induction and recovery are needed for sea turtles, especially in cases eligible for immediate release. This study demonstrates that intravenous propofol provides a rapid induction of anesthesia in loggerhead (Caretta caretta) sea turtles and results in rapid recovery, allowing safe return to water ...

Magnet-induced disorientation in hatchling loggerhead sea turtles [PDF]

Journal of Experimental Biology, 2003
SUMMARYLaboratory experiments have indicated that hatchling loggerhead sea turtles(Caretta caretta) are able to establish and maintain courses using information from the Earth's magnetic field. In previous experiments, turtles were tested in relatively uniform magnetic fields generated by large coil systems surrounding an orientation arena.

Beyond fishing: loggerhead turtle impalement by swordfish

Marine and Fishery Sciences, 2022
Sea turtles are susceptible to a wide range of impacts. In Brazil, the loggerhead turtle Caretta caretta (Linnaeus, 1758) is the main sea turtle species caught incidentally by longline fishing fleets that target the blue shark Prionace glauca (Linnaeus,

Complexity and variation in loggerhead sea turtle life history [PDF]

Biology Letters, 2007
Juvenile loggerhead sea turtles spend more than a decade in the open ocean before returning to neritic waters to mature and reproduce. It has been assumed that this transition from an oceanic to neritic existence is a discrete ontogenetic niche shift. We tested this hypothesis by tracking the movements of large juveniles collected in a neritic foraging
