Elasmobranchii (sharks and rays) > Carcharhiniformes (Ground sharks) > Atelomycteridae (Coloured catsharks)
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 ) .

Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; bathydemersal; depth range 122 - 435 m (Ref. 56497 ). Deep-water

Biology     Glossary (e.g. epibenthic)

Found in deep-reef habitat on the continental slope, generally in depths greater than 250 meters (122-435 m), with deepwater gorgonians, hard corals, tube sponges, crinoids, ophiuroids, and a great number of sympatric scyliorhinid shark Scyliorhinus haeckelii (Ref. 56497 ). Oviparous (Ref. 50449 ); with one egg per oviduct laid at a time. Egg capsule grayish olive (fresh) to brownish (fixed), with filamentous superficial texture (Ref. 56497 ).
