The video data for this project have been collected in a bay of the Red Sea since 2022. The dolphins featured in the videos are not held in captivity, they live freely in the bay.

FAQ

What to answer to the first question "Do you see dolphins in any of these videos" if it is difficult to determine whether there is a dolphin or something else (e.g. a diver)?

If you are not sure whether what you see is a dolphin, we prefer you to answer “yes” to this question.

How to tell if it is the same dolphin or two different ones from one camera to the next?

This can sometimes be tricky. You will need to observe the continuity of the dolphins' movements from one video to the next. Often, as a dolphin begins to disappear from one panel, it simultaneously begins to appear in another.

How many dolphins can there be at most?

There are two individual dolphins on the site.

Why describe what dolphins are doing and what is around them?

We seek to associate behaviours with vocalizations. So we need your answers to make first rough classifications.

How to tell if they are being fed?

Dolphins are sometimes fed using the poles below. If you see them almost motionless at the end of the poles, with bubbles and fish around, you can assume they are eating.

On above-water videos, the three poles are located at the bottom left of the screen. As with underwater videos, if you see them motionless in this area, they are probably eating (Note that this spot is often hidden behind the time bar, we suggest to open the video in full-screen mode).

We should have listed the most common answers to two context questions, but what if none of the categories seem to fit?

In the “Other” category, you could, for example, enter “Interacting with divers”, ”Swimming around the feeding zone”, ”People on the pier”, etc.

Even if you are unsure, your best guess is valuable! We are interested in anything that could help us understand how dolphins behave and communicate in different situations.

What do dolphins do when splashing their tail?

This means they are probably hunting fish.

Additional information: Underwater camera's field of view

The underwater camera field of view provides an large view of the surrounding area.
Note that the fields of view of some cameras overlap, meaning the same area or behaviour may be visible from multiple angles.
