The banded houndshark (Triakis scyllium) is a species of houndshark, in the family Triakidae, common in the northwestern Pacific Ocean from the southern Russian Far East to Taiwan. Found on or near the bottom, it favors shallow coastal habitats with sandy or vegetated bottoms, and also enters brackish water. This shark reaches 1.5 m (4.9 ft) in length. It has a short, rounded snout and mostly narrow fins; the pectoral fins are broad and triangular, and the trailing margin of the first dorsal fin is almost vertical. It is gray above and lighter below; younger sharks have darker saddles and dots, which fade with age.
Nocturnal and largely solitary, the banded houndshark preys on benthic invertebrates and bony fishes. It is aplacental viviparous, with the developing embryos sustained by yolk. After mating during summer, females bear as many as 42 pups following a gestation period of 9–12 months. The banded houndshark poses no danger to humans and adapts well to captivity. It is caught as bycatch off Japan, Taiwan, and likely elsewhere in its range; it may be eaten but is not as well-regarded as related species. Because fishing does not appear to have diminished this shark's population, the International Union for Conservation of Nature (IUCN) has listed it under Least Concern.
