Banded houndshark

The first scientific description of the banded houndshark was authored by German biologists Johannes Peter Müller and Friedrich Gustav Jakob Henle, based on a dried specimen from Japan, in their 1838–41 Systematische Beschreibung der Plagiostomen.

[2] Native to the northwestern Pacific Ocean, the banded houndshark occurs from the southern Russian Far East to Taiwan, including Japan, Korea, and eastern China; records from the Philippines are questionable.

[4] It frequents sandy flats and beds of seaweed and eelgrass; additionally, it is tolerant of brackish water and enters estuaries and bays.

The snout is short, broad, and rounded; the widely separated nostrils are each preceded by a lobe of skin that does not reach the mouth.

The horizontally oval eyes are placed high on the head; they are equipped with rudimentary nictitating membranes (protective third eyelids) and have prominent ridges underneath.

[6] Mating occurs during the summer, and involves the male swimming parallel to the female and gripping her pectoral fin with his teeth; thus secured, he then twists the distal portion of his body to insert a single clasper into her cloaca for copulation.

[1] Known parasites of this species include the tapeworms Callitetrarhynchus gracilis,[10] Onchobothrium triacis, and Phyllobothrium serratum,[11] the leech Stibarobdella macrothela,[12] and the copepods Achtheinus impenderus,[13] Caligus punctatus,[14] Kroyeria triakos,[15] and Pseudopandarus scyllii.

[16] Harmless to humans,[17] the banded houndshark is commonly displayed in public aquariums in China and Japan,[1] and has reproduced in captivity.

[5] This species is often caught incidentally off Japan in gillnets and set nets; the meat is sometimes sold, but is considered to be of poorer quality than that of other houndsharks in the region.

The markings of the banded houndshark become indistinct with age.
