The Confirmed Stranding of an Adult Female Risso's Dolphin, Grampus griseus (G. Cuvier, 1812), in the northeastern Mediterranean Sea
Summary
This report documents a confirmed stranding record of an adult female Risso's dolphin on Turkey's Mediterranean coast, providing necropsy findings and ecological context for a species classified as 'Least Concern' in the Mediterranean. The case contributes to regional marine mammal stranding databases used to monitor cetacean health.
The study aimed to report a confirmed stranding record of an adult female Risso’s dolphin (Grampus griseus) from the northeastern Mediterranean Sea. This species is classified as "Least Concern" in the Mediterranean by the International Union for Conservation of Nature (IUCN). The individual, which was first seen alive from the Erdemli shores of Mersin Bay on 10 April 2023, was tried to push back into the water after being stranded ashore. After the individual died, the corpse was brought to Mersin University Marine Life Museum for external examination. It was determined that the individual weighed 360 kg and had a length of 330 cm. Many old and new scars were found on the individual's skin. It was understood that the newly formed deep cut marks on the head area were caused by the individual hitting the fishing nets. The study is the confirmed stranding of an adult female Risso's dolphin record in the northeastern Mediterranean Sea.

Microplastic Occurrence in the Gastrointestinal Tract of a Risso’s Dolphin Grampus griseus in the Northeastern Mediterranean Sea
A stranded Risso's dolphin in the northeastern Mediterranean was found to contain 454 microplastic particles in its gastrointestinal tract. Fibers and fragments were the most common forms, including polypropylene and polyethylene. This case study documents microplastic ingestion by a cetacean species and contributes to growing evidence of widespread plastic contamination in Mediterranean marine mammals.
Evaluating the presence of microplastics in striped dolphins (Stenella coeruleoalba) stranded in the Western Mediterranean Sea
Researchers analyzed three decades of intestinal content data from Western Mediterranean striped dolphins stranded over 30 years, finding microplastics in 90.5% of dolphins, making it one of the highest contamination rates reported in cetaceans.
The intestinal microbiota of a Risso’s dolphin (Grampus griseus): possible relationships with starvation raised by macro-plastic ingestion
Researchers profiled the gut bacteria of a stranded Risso's dolphin that died after ingesting rubber gloves, finding that starvation caused by plastic obstruction was associated with disrupted microbial diversity and the presence of potentially opportunistic pathogens, offering early evidence linking plastic ingestion to microbiome dysbiosis in cetaceans.
Evaluating the Presence of Marine Litter in Cetaceans Stranded in the Balearic Islands (Western Mediterranean Sea)
Researchers performed necropsies on cetaceans stranded in the Balearic Islands of the western Mediterranean Sea, documenting for the first time the presence, types, and quantities of ingested and entangled plastic marine litter, contributing evidence on plastic debris impacts to cetacean populations in this region.
Mercury and cadmium in striped dolphins (Stenella coeruleoalba) stranded along the Southern Tyrrhenian and Western Ionian coasts
Mercury and cadmium were found at elevated levels in striped dolphins stranded along the Italian coast, with liver showing the highest concentrations. The findings highlight ongoing heavy metal contamination in the Mediterranean Sea and its accumulation in top marine predators, raising concerns for marine ecosystem and food chain health.
