Etymology: Schroederichthys: In honor of American ichthyologist William C. Schroeder (1895-1977), Woods Hole Oceanographic Institution, for his pioneering work (with Henry B. Bigelow) on cartilaginous fishes; ichthyos (Gr.), fish. (See ETYFish); saurisqualus: saurus, from sauros (Gr.), lizard; squalus (L.), a sea-fish, usually applied to sharks, from vernacular “lizard catshark,” presumably referring to its slender, lizard-like body and long tail. (See ETYFish).
