Photography: between science and communication
1:56
A good camera is an essential research tool when at sea: it allows us to collect good scientific data, but also to share emotions and "tell stories". |
|
Dolphins and fishing boats: individual specialization
2:44
When following trawlers, bottlenose dolphins display different feeding patterns, indicative of individual preferences or talents. |

Calm sea, but no dolphins?
1:59
Doing research at sea is nothing like going to the dolphinarium: sometimes the animals are not found at all, and in fact the sighting frequency is a proxy to assess their abundance and distribution. |
|
Approaching the dolphins and reducing disturbance
2:37
In the presence of dolphins, one must avoid maneuvering the boat in invasive ways and allow the dolphins to approach on their own initiative. |

Dolphins and fishing boats: intensive fishing and adaptation
4:52
The waters off the coasts of Veneto are intensively exploited by trawlers: bottlenose dolphins have adapted and learned to forage behind different types of these fishing boats. |

Dolphins and fishing boats: foraging and dangers
