Shortspine Combfish

(Collichthys lucidus)
Population Status in the Wild: Least Concern

The shortspine combfish is a species of deep-sea fish native to the temperate and subtropical waters of the Pacific Ocean, particularly along the coastlines of Japan, the Korean Peninsula, and China. This fish is recognized by its slender, elongated body and short spines on the dorsal fin. Typically, the shortspine combfish has a silver or light grayish coloration with darker markings along its back and sides. It can grow to a length of around 12 to 15 inches, though it is often smaller.

The shortspine combfish is a carnivorous predator, feeding on small invertebrates, plankton, and smaller fish. It is typically found at depths ranging from 100 to 500 meters (328 to 1,640 feet) and is often associated with rocky seafloors and deepwater ecosystems. Its slender body allows it to maneuver through tight spaces, while its sharp teeth and keen senses make it an effective hunter in its dark, deep-sea environment.

One of the defining characteristics of the shortspine combfish is its ability to survive in deeper, colder waters, where oxygen levels are lower, and the pressure is much higher than at the surface. This adaptation allows the fish to exploit ecological niches that other fish species cannot access. Although this species is not as well-studied as other deep-sea fish, it is believed to have a relatively long lifespan and slow reproductive cycle.

The shortspine combfish is classified as Least Concern due to its stable populations and widespread distribution. However, as with many deep-sea fish, it could be vulnerable to overfishing, particularly in areas where deepwater trawling is prevalent. Additionally, habitat destruction from fishing practices and climate change could threaten its population in the future.

Fun Facts:
The shortspine combfish’s slender body helps it navigate and hide in rocky crevices on the ocean floor.

It is primarily a nocturnal predator, hunting during the night when many prey species come closer to the seafloor.

The short spines on its dorsal fin give the fish some defense against predators, making it more difficult to consume.
