sentences:  The genus "Haploblepharus" was created by American zoologist Samuel Garman in 1913, in the 36th volume of "Memoirs of the Museum of Comparative Zoology, at Harvard College", to contain the puffadder shyshark, then known as "Squalus edwardsii".The name is derived from the Greek "haplóos" meaning "single", and "blepharos" meaning "eyelid".In 1988, Leonard Compagno placed "Haploblepharus" with "Halaelurus" and "Holohalaelurus" in the tribe Halaelurini of the family Scyliorhinidae, based on morphological characters.
