(See ETYFish);  naylori: In honor of Gavin Naylor, College of Charleston (Charleston, South Carolina, USA), for contributions and innovative molecular research into the higher classification of chondrichthyans and for his support of the junior author’s work in the Southwest Indian Ridge of the southwestern Indian Ocean.
