Found from southern Russia to China, The Fins United Initiative is excited to introduce you to the banded houndshark (Triakis scyllium)! Relatively widespread and common in this range, they’re found on the continental and insular shelves as well as estuaries or shallow bays. The banded houndsharks like sandy substrates and also like seaweed or eel-grass flats. Reproductivity is largely a mystery but it is known that they are an aplacental viviparous species and give birth to 10-24 pups per litter.
A small shark, they grow up to a maximum total length of 150 cm and feast on small fishes and invertebrates. According to the IUCN website, in Japan the male banded houndsharks mature at 93-103 cm total length (TL) at about 5-6 years old, and females at 106-117 cm TL and 6-7 years old. The pups are born at 18-20cm TL. Males tend to live 15 years and 18 years for females.
Little else is known about these sharks, but because of their widespread distribution and the fact they are commonly seen in China and Japan, the IUCN has assessed them as Least Concern (LC).
