Acquisition of magnetic directional preference in hatchling loggerhead sea turtles

Journal of Experimental Biology, 1994
ABSTRACT During their natal migration, hatchling loggerhead sea turtles (Caretta caretta L.) establish courses towards the open ocean and maintain them after swimming beyond sight of land. Laboratory experiments have demonstrated that swimming hatchlings can orient using the earth’s magnetic field. For the magnetic compass to function in

Movements of marine and estuarine turtles during Hurricane Michael

Scientific Reports, 2021
Natural disturbances are an important driver of population dynamics. Because it is difficult to observe wildlife during these events, our understanding of the strategies that species use to survive these disturbances is limited.

Evaluation of a portable glucometer for blood glucose measurement in juvenile green sea turtles (Chelonia mydas)

Australian Veterinary Journal, Volume 104, Issue 10, Page 661-666, October 2026.
Blood glucose is a key physiological indicator in sea turtles, but its measurement in field settings can be challenging. Portable point‐of‐care (POC) glucometers offer practicality, yet their agreement with reference laboratory methods has not been established for juvenile green sea turtles (Chelonia mydas) from the Southwestern Atlantic.

Interspecific Gene Flow and Potential Hybrid Breakdown in South Atlantic Sea Turtles

Molecular Ecology, Volume 35, Issue 20, October 2026.
ABSTRACT Interspecific hybridisation can play an important evolutionary role, generating new taxa or outbreeding depression, which can also lead to behavioural reproductive isolation through reinforcement. Still, there are few studies investigating how divergence time relates to hybridisation rates and its impact on introgression. Sea turtles are known

Change of perspective: using aerial surveys to identify human-turtle interactions in the Ningaloo Marine Park [PDF]

, 2009
Shore-based turtle tourism is emerging as a popular activity for independent travellers during the summer months in the Ningaloo Marine Park, yet little is known about the spatial extent of human-turtle interactions and their impact on nesting marine ...

Correlations between local geoclimatic variables and hatchling body size in the sea turtles Caretta caretta and Chelonia mydas

BMC Ecology and Evolution
It has been widely demonstrated that air and sand temperatures influence the anatomy of sea turtle hatchlings. We examined the impact of precipitation during the nesting season on the hatchling body size of loggerhead and green turtles from 37 beaches ...

Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola

The Anatomical Record, Volume 309, Issue 9, Page 2286-2297, September 2026.
Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...

De novo transcriptome assembly of loggerhead sea turtle nesting of the Colombian Caribbean

Genomics Data, 2017
Loggerhead sea turtle Caretta caretta is widely distributed in the oceans of tropical and subtropical latitude. This turtle is an endangered species due to anthropic and natural factors that have decreased their population levels.

Satellite‐Based Fishing Fleet Tracking: A New Foundation for Fisheries Science and Management

Fish and Fisheries, Volume 27, Issue 5, Page 1134-1150, September 2026.
ABSTRACT Satellite‐based vessel‐tracking technologies have ushered in a new era for monitoring fishing activity at scale. By combining artificial intelligence (AI) methods with remotely‐sensed data, researchers can now detect, classify and analyse fishing behaviour across vast and previously unobservable ocean regions.
