# Nomenclatura L-number

Le difficoltà inerenti al riconoscimento e la differenziazione delle specie e sottospecie ha spinto il commercio dei pesci tropicali a sviluppare un proprio sistema di classificazione, conosciuto Nomenclatura L-number per i Loricariidae (i tradizionali "pesci pulitori"), una piccola ma studiata famiglia che mostra in apparenza notevoli differenze. Questo sistema usa la lettera L per identificare individui con livree e colori che non sono riconosciuti dai biologi. Talora capita che, nel momento in cui una specie viene classificata, abbia già un suo L-number associato
