Brown meagre's hole II

We went back to dive in one of the holes where we are sure to meet Brown meagre, Sciaena umbra. We often dive into the same holes not only because we are sure of filming particular species of fish, but also in some way to try to monitor the health of our sea and the biodiversity that we increasingly hope to find.

The surprise in this apnea dive, condensed in the video into three consecutive dives, was not so much that of finding the croakers, but from the first dive we met four specimens of Mediterranean brown grouper, (Dusky grouper) Epinephelus marginatus, which share the same den. Together we also found several species of sparidae, white bream and saddled bream and the ubiquitous black damselfish, Chromis chromis.

The fact that two species of predators, Brown meagre and Mediterranean grouper, inhabit the same hole and therefore share the same habitat harmoniously with other fish species, makes us hopeful with respect to safeguarding the biodiversity of our seas.

We have to remember that biodiversity means that an ecosystem is as stable as possible in relation to the biological differentiation between individuals of the same species, in relation to environmental conditions; and that also the coexistence in the same ecosystem of different animal and plant species creates a balance thanks to their reciprocal relationships.

In this video the exceptional transparency of the water must not mislead us, we are on a rocky bottom varying from 8 meters deep at the top of the hole, up to 13 meters of the hole itself, and 15 meters at the base, therefore quite accessible depths in freediving if well trained. With tanks it would have been almost impossible to get so close to these fish. The same hole that we have often filmed is also about 200 meters from the rocky and jagged coast and therefore represents the typical coastal habitat of the Mediterranean Sea.
