Lepidophagy (original) (raw)
Lepidophagy is a specialised feeding behaviour in fish that involves eating of scales of other fish. Lepidophagy is widespread, having been independently evolved in at least five freshwater families and seven marine families. A related feeding behavior is pterygophagy, which are fish that feed on the fins of other fish.

| dbo:abstract | Lepidophagy is a specialised feeding behaviour in fish that involves eating of scales of other fish. Lepidophagy is widespread, having been independently evolved in at least five freshwater families and seven marine families. A related feeding behavior is pterygophagy, which are fish that feed on the fins of other fish. (en) La lépidophagie (Lat. lepidos (écaille)) est le régime alimentaire qui consiste à manger des écailles de poissons. On la trouve chez certains poissons, comme le Catoprion mentonnier, ou les Perissodus du lac Tanganyika, dans au moins cinq familles d'eau douce et sept familles marines. Les branchioures, ou « poux de poissons » peuvent aussi présenter ce régime alimentaire. Les écailles de poissons sont une source de nourriture étonnamment nutritive, des couches contenant de la kératine et l'émail, ainsi que d'une partie dermique et une couche de mucus riche en protéines. Ils sont une source riche de phosphate de calcium. * Portail de la zoologie * Portail de l’ichtyologie (fr) La lepidofagia è un comportamento animale relativo alla predazione specializzato nel nutrirsi delle scaglie dei pesci.È una caratteristica specifica dei pesci, registrata in almeno 5 famiglie di pesci d'acqua dolce e in 7 di pesci d'acqua salata. Le scaglie dei pesci sono un'ottima fonte nutritiva, in quanto comprendendo gli strati di cheratina e smalto, così come una parte cutanea e uno strato di muco sono estremamente ricche di proteine e fosfato di calcio. Tuttavia i pesci lepidofaghi non hanno grandi dimensioni (difficilmente queste specie superano i 12 cm di lunghezza) e ciò è dovuto alla grande quantità di energia spesa per procurarsi solo poche scaglie ad ogni attacco (ogni specie ha sviluppato tecniche differenti per strappare scaglie alle prede). Cibo che comunque è sempre disponibile, essendo una parte rinnovabile velocemente e soprattutto parte integrante dell'epidermide della quasi totalità dei pesci. (it) |
