This discipline, well known in italian as "Cacciafotosub", is consisting to capture, with the camera optic, the largest number of fishes species. It is possibile to accomplish such captures, following two different ways: by apnea and by scuba, from who we can distinguish two categories: "Sport" (by apnea only) and "Scuba" (by aqualung only). Psychophysics training and specific aquaintance of the marine species populating the Mediterranean sea, are requested. That's keeping such activity even more interesting, just because's pushing us to encrease our knowledge of this still partially discovered world. Rules are simples! To present the Jury, pictures with the following features: absence of technical errors (correct exposure and focus); clearly distinguishable specie; minimum size for the subject not lesser than 1/3 of the longer side of the frame. Additionally, it is not allowed to display more than one image, showing the same specie. There are samples belonging to the same specie that, sometimes, it seems to appear like being part of different species ( what happens, for instance, in sexual dimorphism), as showed in the pictures below:
This "labride" shows, while growing, some Another frame, showing the same subject
substantial variation of the colors body. Picture from the left, in a male nuptial color.
shows the red variant of the "Symphodus ocellatus".
This picture shows a commonly named "Donzella" This image shows a male "Coris Juli" with its
(Coris Juli). Such specie's showing a Particular colors at the maximum radiance. It could to
feature, shared with other species too: the ability appear, to a non-used eye, as if the two
to change sex in case of death of the dominant samples here showed, aren't from the same
male! Will be the biggest sized female to slowly specie. Well, it isn't this way! We are still
become a male one. The picture above shows observing a "Coris Juli"!
the transition color body of a "Coris Juli" female,
passing to the male status.
