Dwarf lantern sharks have a more well-known relative, the velvet belly lantern shark. This had led them to think dwarf lantern sharks give birth to 2 or 3 young at a time, which usually measure between 5.5 to 6 cm long at birth. Scientists today actually still don’t know much about the breeding behavior of dwarf lantern sharks, and heavily rely on inferences based on studies of their relatives. When that time comes, they then give birth to their young. However, female dwarf lantern sharks don’t lay their eggs, and instead, keep them inside their bodies until they hatch. Scientists call this aplacental viviparous and involve the young growing inside the eggs. They also simultaneously lay eggs and give birth to live young. Their tails also feature black bands and blotches. Their scales have random patterns, though, dwarf lantern sharks tend to have a dark brown color with black markings along their lower bodies. The second of the two fins also grows twice as big as the first, as well as the rest of the fish’s fins.ĭwarf lantern sharks also have small tails, slightly rounded with a notch below it. They also have short trunks, with two fins on top of their bodies, closely spaced to each other, and both with grooved spines in front.
They have big, bulbous eyes, which help them see in the dark of the deep sea they live in. Dwarf lantern sharks have a distinctive appearance.
