These images show two very common species on the island: the Atlantic trumpetfish (Aulostomus strigosus) and the Mediterranean parrotfish (Sparisoma cretense), which, despite its name, is found in huge numbers around the Canary Islands in the Atlantic.
Both pictures share this stylistic blurred-background effect, which can be archieved by tracking the movement of the fish while photographing it which a relatively slow shutter speed.
