CHE SIGNIFICA TUATARA IN INGLESE
Tuatara
Tuatara sono rettili endemici della Nuova Zelanda e che, pur essendo simili a gran parte delle lucertole, fanno parte di una linea distinta, l'ordine Rhynchocephalia. Le due specie di tuatara sono gli unici sopravvissuti membri del loro ordine, che fiorirono circa 200 milioni di anni fa. Il loro più recente antenato comune con qualsiasi altro gruppo esistente è con gli squamati. Per questo motivo, i tuatara sono di grande interesse nello studio dell'evoluzione delle lucertole e dei serpenti, e per la ricostruzione dell'aspetto e delle abitudini dei primi diapsidi. Tuatara sono marrone verde e grigio e misura fino a 80 cm dalla testa alla punta della coda e pesano fino a 1,3 kg con una cresta spinosa lungo la schiena, particolarmente pronunciata nei maschi. La loro dentizione, in cui due file di denti nella mandibola superiore si sovrappongono a una fila sulla mascella inferiore, è unica tra le specie viventi. Sono inoltre insolite per avere un occhio fotorecettivo pronunciato, il "terzo occhio", che si pensa sia coinvolto nell'impostazione dei cicli circadiani e stagionali. Sono in grado di ascoltare, anche se nessun orecchio esterno è presente e presenta una serie di caratteristiche uniche nel loro scheletro, alcune delle quali apparentemente evolutamente conservate dai pesci.
definizione di tuatara nel dizionario inglese
