Field data on paper





Observing striped dolphins and recording group size and behaviour data onto printed forms. While computer-assisted data collection is often convenient, some field data are easily and reliably recorded on paper.

Dorsal fins scaled



This image shows the proportion between the dorsal fin of a Risso's dolphin and those of striped dolphins (one adult and one calf). The large animal is of course "Yaya", the only Risso's dolphin found in the Gulf of Corinth.

Imperial blackfish and loggerhead sea turtle (the odd couple)



Juvenile imperial blackfish Schedophilus ovalis find shelter under jellyfish and other floating objects adrift (also see THIS POST). This individual chose... a juvenile loggerhead sea turtle Caretta caretta

While the fish has grown larger than the turtle, who can no longer provide an appropriate shelter, the two seemed unseparable. A group of striped dolphins encountered them and a dolphin kicked the turtle with its flukes. However, the imperial blackfish would not run away, always staying in the turtle's shade.

The odd couple kindly let us approach for a minute and film them with a pole-mounted camera. We hope that nobody will take advantage of their confident behaviour, or break their bond.

Catch of the day



This much fish will hardly cover the cost of petrol. Not a good day for this artisanal fisherman operating trammel nets in the Gulf of Corinth.

Many artisanal fishermen blame declining catches on overfishing by trawlers and purse seiners.

Stingy catch



Common stingrays Dasyatis pastinaca are plentiful this year, and artisanal fishermen in the Bay of Itea complain because they catch too many of them. Stingrays have little if any market value: they are mostly considered as bycatch and discarded once dead (like the animal portrayed in this image). Proliferation of stingrays is often associated with ecosystem unbalance caused by overfishing and other anthropogenic causes.

Multi-species, multi-age group



Female Risso's dolphin "Yaya", the only member of her species living in the Gulf of Corinth, is always found in mixed groups with striped and (sometimes) short-beaked common dolphins.

Here Yaya swims in the company of two striped dolphins with their calves (one calf swims under the mother to the left), and one short-beaked common dolphin with her calf.

New Hope



The female nicknamed "Hope" is one of the very few short-beaked common dolphins surviving in the Gulf of Corinth (just a few tens individuals, and declining).

Two days ago Hope was sighted together with a small calf. The calf looked like a striped dolphin, possibly being the outcome of inter-specific breeding with a male striped dolphin (or alternatively a pure striped dolphin calf that Hope was temporarily babysitting).

Hope and the calf approached our boat for a short while, allowing Silvia and Mariana to take these photos. The baby looked healthy and energetic.

Imperial blackfish



Two beautiful imperial blackfish Schedophilus ovalis found shelter under an old fridge floating adrift in the Gulf of Corinth.

Juveniles of this species are known to hide under jellyfish or floating objects. It is the first time we see these animals in Greece.
