N. brevirostis, commonly known as the Short-tailed Nurse Shark, is found in warm coastal waters, often inhabiting coral reefs and rocky areas. This species is distinguished by its short, rounded snout and small eyes. It is nocturnal, feeding on fish and invertebrates, and plays a crucial role in the marine ecosystem as a predator.

N. brevirostis, commonly known as the Shortspine Spurdog, is native to the northwest Pacific Ocean. Its distribution includes the waters off the coasts of Japan, Korea, China, and Taiwan. The species can be found from the shallow continental shelf to deeper offshore waters.

The Shortspine Spurdog inhabits marine environments characterized by temperate waters. It is typically found at depths ranging from 100 to 600 meters, although it can occasionally be found deeper. The water temperature in these regions usually ranges from 4°C to 15°C.

N. brevirostis occupies a benthopelagic ecological niche, meaning it lives near the bottom of the ocean but can also be found swimming in mid-water. It is a predator that feeds on various fish and invertebrates. The species has adapted to life in deep-sea environments with limited light and colder temperatures, utilizing its keen sense of smell and lateral line system to detect prey.
