Bythaelurus
Bythaelurus is a genus of deep-water catsharks and part of the family Scyliorhinidae. The genus Bythaelurus Compagno 1988 was first described as a subgenus of Halaelurus Gill 1862 based on several morphological characteristics including a soft body with thin skin, a bluntly rounded snout without a pointed, knob-like tip, and eyes not noticeably elevated on the dorsal surface of the head. Members of this genus are generally found in deep water and have more somber body coloration.[1]
