Questo minuscolo pesce è armato di 1800 denti - Il giornale del mare
Skip to content Nettorhamphos radula
Alcuni ricercatori hanno scoperto una nuova specie di pesce lungo appena qualche centimetro ed armato di una mascella con più di 1800 denti. Squali, coccodrilli, piranha… senza dubbio il mondo acquatico è ricco delle mascelle piu’ efficaci e terrificanti del pianeta. A queste specie si aggiunge un piccolo pesce lungo circa 4 cm battezzato Nettorhamphos radula. Lo studio è stato portato avanti dai ricercatori dell’Università di Washington in conpartecipazione con la Texas A & M University ed il museo di Stato dell’Australia occidentale.
Il pesce Nettorhamphos radula scovato in Australia era conservato nel Museo dal 1977 ma non era mai stato studiato ne tanto meno osservato da vicino da occhi “scientifici”. La specie appartiene alla famiglia dei Gobiesocidae che raggruppa 166 specie conosciute divise in 47 generi. Oltre una mascella ricca di piccoli dentelli questo pesce possiede anche un disco adesivo ventrale che gli permette di ancorarsi alla superficie.
Scannerizzazione 3d Nettorhamphos radula 2 I ricercatori hanno trovato tra i campioni conservati al museo due esemplari di Nettorhamphos radula conservati in buono stato e che hanno permesso una scannerizzazione 3D. Risultato: Da 1800 a 2300 denti.
