Description of cloacoscopy in the loggerhead sea turtle (Caretta caretta) [PDF]

Acta Veterinaria Brno, 2016
The aim of the study was to describe cloacoscopy in the loggerhead turtle ( Caretta caretta ) and to evaluate its efficacy in clinical practice. Cloacoscopy was performed on 31 turtles, 23 females and 8 males.

Listening to tuna: Acoustic characterization of captive juvenile yellowfin tuna (Thunnus albacares)

Journal of Fish Biology, EarlyView.
Abstract The effectiveness of passive acoustic monitoring (PAM) for studying marine biodiversity highly relies on comprehensive libraries of species‐specific sounds. While sound production is well‐documented in reef and freshwater fishes, the acoustic behaviour of ecologically and economically vital pelagic species like tunas still remains largely ...

Tropical vs. temperate sea turtle population resilience to extreme temperatures

Ecological Indicators
Rising temperatures due to global warming over the last decades pose threats to marine biodiversity. Sea turtles are ectothermic species, and their embryonic development depends on nest conditions, particularly temperature.

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 ...

Strandings of cetaceans and sea turtles in the Alboran Sea and Strait of Gibraltar: a long–term glimpse at the north coast (Spain) and the south coast (Morocco)

Animal Biodiversity and Conservation, 2011
A total of 13 species of cetaceans and three species of marine turtles were found in this study. Data were collected by eight independent and self–regulated stranding networks, providing information about 1,198 marine mammal (10 odontocetii, three ...

Do costal erosion and urban development threat loggerhead sea turtle nesting? Implications for sandy beach management

Frontiers in Marine Science, 2023
Nest beach selection by sea turtles at a regional scale may depend on upper shore environmental cues. Thus, the variability of sandy beach conditions, including coastal erosion rates and urban development can affect their nesting ecology.

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.

Loggerhead sea turtle abundance at a foraging hotspot in the eastern Pacific Ocean: implications for at-sea conservation

Endangered Species Research, 2014
The Pacific Coast of the Baja California Peninsula (BCP), Mexico, is a hotspot for foraging loggerhead turtles Caretta caretta originating from nesting beaches in Japan.

Umbilical Cord: A Non‐Invasive DNA Source for Sea Turtle Genomics

Molecular Ecology Resources, Volume 26, Issue 6, August 2026.
ABSTRACT High‐throughput sequencing has revolutionised conservation genomics by enabling genome‐wide information even in non‐model species. However, obtaining non‐invasive samples for genomics remains challenging in species like sea turtles, which spend most of their lives in the open ocean.

Bioaccumulation and biomagnifications of toxic metals in tissues of loggerhead turtles (Caretta caretta) from the Mediterranean Sea coast, Egypt

Scientific Reports, 2023
Heavy metal concentrations in the different tissues of marine turtles are presented; the most frequently monitored elements are mercury, cadmium, and lead. Concentrations of Hg, Cd, Pb, and As in different organs and tissues (liver, kidney, muscle tissue,
