Biomimetics
This monofin model, a Lunocet Pro intended for free diving, was clearly inspired by cetacean flukes. A persuasive example of biomimetics.

Striped dolphin nearshore
Striped dolphin off the northern coast of the Peloponnese. Striped dolphins are pelagic animals and finding them so close to shore is rather unusual.

Tight bottlenoses
A group of bottlenose dolphis surfacing in tight formation in the Bay of Itea. Among them, the most 'resident' of all, nicknamed Codo, a female with abnormal and almost missing flukes (who, however, seems to be doing just fine).

End of the field season
This year's field research season has ended, but we aim to be back soon. The photo shows a nice gift from our former field assistant Annalucia Cantafaro.

New dorsal fin marking
A fresh new notch has appeared on the dorsal fin of this striped dolphin.
Matching thousands of dorsal fin photos belonging to hundreds of different animals would be hard enough, but it becomes even harder when one is required to consider dorsal fin changes that may have occurred over time. Failure to track evolution of fin markings will result in wrong additions of new individuals in the catalogue, and therefore biased estimates of abundance. One must be very careful.

Coastal dolphins
This is about as close as bottlenose dolphins can get to the coast. Well... they do get even closer sometimes.

Can you spot the dolphins?
Bottlenose dolphins aren't easy to spot when they surface amid fish farm cages, buoys and pipelines. Such environment may not look 'natural', but that's where they can manage to find some food.

Survey effort in the Gulf of Corinth
While the Gulf of Corinth is a relatively large area (2,400 km2) to be surveyed with small boats, and often wavy, we try to cover it as best we can searching for dolphins and other fauna. Survey effort in this area has reached 34,000 km. The map shows our navigation tracks in years 2011–2015.

Same boat, different catch
In 1973 Argyris Andressakis could still catch big groupers with his rowing wooden boat, right off the port of Galaxidi, Greece.
Fourty-two years later, boat, area and fishing gear have remained the same. However, for Dimitris Andressakis – Argyris' son – catching a grouper has become unimaginable. A small cuttlefish is a more likely catch.
It doesn't take a scientist to notice that baselines, here and elsewhere, have shifted tremendously in just a few decades.
