Morphological features of the nasal cavities of hawksbill, olive ridley, and black sea turtles: Comparative studies with green, loggerhead and leatherback sea turtles. [PDF]

open access: yesPLoS ONE, 2021
We analyzed the internal structure of the nasal cavities of hawksbill, olive ridley and black sea turtles from computed tomography images. The nasal cavities of all three species consisted of a vestibule, nasopharyngeal duct and cavum nasi proprium that ...

The genome sequence of the Loggerhead sea turtle, Caretta caretta Linnaeus 1758 [version 2; peer review: 2 approved] [PDF]

open access: yesF1000Research, 2023
We present a genome assembly of Caretta caretta (the Loggerhead sea turtle; Chordata, Testudines, Cheloniidae), generated from genomic data from two unrelated females. The genome sequence is 2.13 gigabases in size.

Heart rate and cardiac response to exercise during voluntary dives in captive sea turtles (Cheloniidae) [PDF]

open access: yesBiology Open, 2020
In chelonids, oxygen is primarily stored in the lungs during a dive. Therefore, management of blood oxygen transportation to peripheral tissues by cardiovascular adjustments during submergence is crucial to maximize their dive duration, and consequently,

Marine turtles are only minimally sexually size dimorphic, a pattern that is distinct from most nonmarine aquatic turtles [PDF]

open access: yesEcology and Evolution, 2022
Turtles have been prominent subjects of sexual size dimorphism (SSD) analyses due to their compact taxonomy, mating systems, and habitat diversity. In prior studies, marine turtles were grouped with fully aquatic non‐marine turtles (NMATs).

Heterochromatin and microsatellites detection in karyotypes of four sea turtle species: Interspecific chromosomal differences [PDF]

open access: yesGenetics and Molecular Biology, 2020
The wide variation in size and content of eukaryotic genomes is mainly attributed to the accumulation of repetitive DNA sequences, like microsatellites, which are tandemly repeated DNA sequences.

An ancestral hard-shelled sea turtle with a mosaic of soft skin and scutes [PDF]

open access: yesScientific Reports, 2022
The transition from terrestrial to marine environments by secondarily aquatic tetrapods necessitates a suite of adaptive changes associated with life in the sea, e.g., the scaleless skin in adult individuals of the extant leatherback turtle.

First record of the hawksbill turtle (Eretmochelys imbricata, Reptilia: Testudines: Cheloniidae) from South Korea

open access: yesJournal of Asia-Pacific Biodiversity, 2020
To conserve national biodiversity, enlisting and detailed morphological description of unrecorded species is critical. Here, we, for the first time in Korea, report and describe detailed morphological characteristics of two juvenile hawksbill turtles ...

Ancient DNA Analysis and Stable Isotope Ecology of Sea Turtles (Cheloniidae) from the Gold Rush-era (1850s) Eastern Pacific Ocean

open access: yesOpen Quaternary, 2018
Historical and archaeological evidence documents the importation of sea turtles from the eastern Pacific Ocean (Baja California) to California during the Gold Rush (1848–1855) and through the end of 19th century, but it is unknown whether these 19th ...
