"Yaya" is the only Risso's dolphin in the Gulf of Corinth, Greece. She lives with striped dolphins and common dolphins in a unique multi-species society. Long ago, Yaya must have managed to survive a shark attack: she still carries a large wound on the right side of her body. The wound has completely healed. We studied Yaya for a decade, and it's been terrific.

In June 2016, we documented what looked like grieving behaviour by a striped dolphin Stenella coeruleoalba towards a subadult conspecific. The event was filmed during a Marine Biology Field Course by Texas A&M University, organised in collaboration with OceanCare and Dolphin Biology and Conservation in the Gulf of Corinth, Greece. For more information on cetacean responses to dead conspecifics (and whether or not it may be grieving) check out THIS ARTICLE.

Enjoy 15 minutes of relaxation and awe, watching striped, common and admixed dolphins living their blue life in the transparent waters of the Gulf of Corinth, Greece. We filmed them with GoPro cameras between 2013 and 2016, as they swam around our research boat.

Sea turtles make a relatively common encounter in the blue waters of the Gulf of Corinth, Greece. Over the years we filmed several of them, above and below the surface. Here, we show a selection of our best sea turtle footage, also featuring the occasional associated fish.

Jellyfish blooms are increasingly common, worldwide. We filmed this amazing bloom while conducting research on dolphins in the Gulf of Corinth, Greece. This species, the Mediterranean jelly Cotylorhiza tuberculata, is exceptionally beautiful.

For centuries, humans have been using the oceans as garbage bins. In recent decades, plastic has colonised the marine environment to the point of becoming an all-pervading component of marine life. This short video shows 10 cases of fish co-occurrence with plastic debris floating adrift in the Gulf of Corinth, Greece.

Dolphin Biology and Conservation, in collaboration with OceanCare, has conducted intensive field research on dolphins in the Gulf of Corinth, Greece. This documentary, produced by Jens Kramer in July 2013, features several DBC researchers, interviews with local fishers, and some of the field activities that took place between 2009 and 2017.

This Texas A&M University course consisted of lectures and labs on the ecology and behavior of marine mammals. The course provided opportunities of observing and recording data on marine fauna, assisted by experienced researchers. It also included visits to cultural heritage sites and fishing ports. This short video shows some of the activities during the course held in 2014.

We studied striped and common dolphins in the Gulf of Corinth, Greece, between 2009 and 2017. Here, we document one of many encounters with these amazing marine mammals, fast traveling and swimming around our inflatable boat in May 2016.

Quiet and friendly dolphins, beautiful cloudy sky, calm blue sea. The perfect day for dolphin researchers. Filmed in Greece in September 2014.

The amazing grace of striped dolphins in the Gulf of Corinth, Greece. Filmed underwater while socialising and bowriding the research boat.

While studying bottlenose dolphins in the Southern Evoikos Gulf, Greece, we recorded the acoustic behaviour of dolphins foraging in the proximity of coastal fish farms. The "sound" part is followed by a brief overview by our collaborator Lavinia Eddy. Filmed in October 2014.

An evening of dolphin research in the Gulf of Corinth, Greece, observing a single Risso's dolphin in a large multi-species group of striped dolphins and common dolphins. We tracked dolphin movements, recorded group size and behaviour, took hundreds of photos for individual photo-identification, and timed the surfacing intervals of the Risso's dolphin. Dolphin research in the Gulf was conducted between 2009 and 2017 in the context of a long-term study supported by OceanCare. Featured scientists include Silvia Bonizzoni, Lavinia Eddy and Nicola Stoppelli.

A short excerpt from an interview with artisanal fishers in the Southern Evoikos Gulf, Greece. These fishers often complain about dolphins depredating fishing gear... but ultimately blame industrial fisheries for the collapse of fish stocks.

Marine conservation biologist Giovanni Bearzi argues that focusing on the threats that cause direct mortality to whales and dolphins is not sufficient. Indeed, important threats are indirect, and originate from human impacts that are global and pervasive. These include calamities such as the widespread loss of marine biodiversity caused by over-exploitation and destructive fishing gear, ever-increasing anthropogenic noise, or the changes resulting from ocean warming and acidification. Emphasis on the most proximate threats to cetaceans is good... but it shouldn't divert attention from the ubiquitous basin-wide offences generated by human encroachment. Our collective focus should be on management action leading to a real improvement of environmental conditions, which must include a serious reduction of destructive human impacts. Therefore, a commitment to cetacean conservation should incorporate a heartfelt intention to "rewild" our seas, primarily by restoring habitat quality and a rich diversity of life, so that cetaceans won't be merely allowed to survive, but can actually prosper.

Il biologo marino Giovanni Bearzi spiega perché concentrarsi esclusivamente sulle minacce dirette a balene e delfini non costituisce una strategia di conservazione efficace. La nostra attenzione dovrebbe andare alle azioni gestionali che portano a un miglioramento reale della qualità ambientale, e a una seria politica di riduzione degli impatti umani più distruttivi. Enfatizzare le minacce più dirette per i cetacei è una buona cosa... ma non dovrebbe sviare l'attenzione sulle offese più diffuse e dilaganti generate dall'accanimento umano, come il sovrasfruttamento causato dalla pesca, il rumore marino e, ovviamente, il riscaldamento e l'acidificazione degli oceani. Dobbiamo impegnarci a "rinaturalizzare" i nostri mari ripristinandone la ricchezza e la bellezza, in modo che ai cetacei non sia consentito solo di sopravvivere, ma possano prosperare.

During a dolphin survey in the Gulf of Corinth, Greece, we spotted a loggerhead sea turtle floating at the surface. From far away it looked like the turtle could be resting, but then we noticed that she was hooked on a fishing longline. In previous years we had managed to release a few sea turtles entangled in fishing gear. This time, however, it was just too late.

The encounter with a freshly-dead striped dolphin during a survey in the Gulf of Corinth, Greece. This individual showed no external signs that could help determine the cause of death. Lesions on the lower jaw were caused postmortem by pecking seagulls.

In December 2009, seven sperm whales stranded alive along the coast of Gargano, Italy. It did not end well. We happened to be there, and we contribute some footage of the live stranding.
