Careproctus spiraki, or pimpled snailfish, is a small, marine, bottom-dwelling snailfish. The type specimen was collected in a bottom trawl 457 meters deep in Seguam Pass in the Aleutian Islands. The species was first described to science by J. W. Orr in 2021.[1][2]
The description of this species is based on 19 individuals collected from deep water in the western Aleutians from 2000 to 2018. Their length varied from 38.7 mm to 52.5 mm. The head is rounded and tapers to a slender tail. They had between 38 and 43 dorsal-fin rays and 10 to 12 caudal-fin rays. They had 4 to 8 gill rakers. The mouth of this species is about 1 cm wide and is lined with small teeth.[1]
These fish are pink-colored. Since seawater absorbs longer wavelengths of light, this color makes them harder to see for predators.[3]
This species is distinguished from similar North Pacific snailfishes by its more slender body which is covered in small bumps topped with tiny prickles, and anterior dorsal-fin rays that stick out of the fin's membrane. It is distinguished from the similar Careproctus maslenikovae by its more slender, less robust body.[1]
