Dolphins Encounter

Encountering dolphins in our seas is fairly easy, but it's one thing to spot them while sailing or see them leaping in the distance, and quite another to find them "playing under the boat", almost touching them. For us, August 15th has become a regular event. The video really was actually taken on August 16th, about 7-8 miles off the Livorno coast ...

Golden anemone - Condylactis aurantiaca

Golden anemone, Condylactis aurantiaca, or sand anemone, is one of the most beautiful anemones endemic to the Mediterranean Sea, both for the colorful arms and the large size it can sometimes reach.

This crustacean of the Majidae family was very common about thirty years ago, and specimens like the one we see in the video were very easy to find in the intertidal tidal pools, provided they had plenty of rocks to hide in and algae to grow on their backs to camouflage them from predators. ...

Blue spiny starfish

Coscinasterias tenuispina, Variable starfish or Spiny starfish is an echinoderm very common in the Mediterranean Sea. It is one of the most common starfish in the "Mare nostrum" and I would also say one of the most fascinating. Usually Echinoderms (sea urchins and starfish) have a pentaray symmetry.

When we explore our underwater reefs we are often amazed by the number of species that we find in a few square meters and as in this case even in a few square centimeters. We have said it many times that biodiversity makes a habitat and an ecosystem more stable, solid and long-lasting. Often we fail to realize the quantity of different species that live next to each other and obviously it is almost impossible to know ...
