dermal denticles.^[2] This species may also be referred to as the smooth lanternshark or the blurred smooth lanternshark.^[3]

pelagic and occurs at depths of 110–700 m (360–2,300 ft) in open water, and from 163 m (535 ft) to over 1 km (0.62 mi) near the bottom.^[4] Like many other lantern sharks, adults are found deeper than juveniles.^[2]

orbit. The mouth has long furrows at the corners that extend halfway to the first of five gill slits. There are 19–24 tooth rows in the upper jaw, each with a narrow central cusp flanked by 2–4 pairs of smaller cusplets, increasing in number with age in males over 45 cm (18 in) long. There are 25–39 tooth rows in the lower jaw, each tooth with a smooth-edged, knife-like cusp and their bases interlocked to form a single cutting surface; the teeth of males over 43 cm (17 in) long and females over 35 cm (14 in) long become more erect with age.^[2][4]

caudal fin with a well-developed lower lobe and a broad upper lobe with a ventral notch near the tip. The small, blocky dermal denticles are densely but irregularly arranged, each with a flat, truncate crown. The coloration is brown or gray above, with a pale spot over the pineal gland, and black below extending in faint markings over the sides of the head, under the pectoral fins, over the pelvic fins, and below the caudal peduncle.^[2][4] Like other lanternsharks, the blurred lanternshark possesses a species-specific light-emitting photophores

intestine (16–19 versus 10–13).^[2]

sexual maturity at around 31–39 cm (12–15 in) long, and females at 38–47 cm (15–19 in) long.^[4]
