![]() ![]() ![]() Evidence proves short, but what exists points to the species badly affected by oil spills in the region, such as in 2010. This, however, has not protected them from environmental issues which affect the heavily developed waters of their home. That said, they seem to have a bigger range, living in the Gulf of Mexico off of Florida, Texas, and Mexico.įringe fin lantern sharks live in deep waters, up to 900 meters under the surface, which makes it difficult to study them. Fringe fin lantern sharks grow bigger than dwarf lantern sharks, but not by much, only up to 30 cm long. They get their names from distinctive filaments running along the fringes of their fins.

This species also has a reputation for having large numbers of parasites in their bodies. They also live deep in the ocean, at depths of up to 2.4 km under the surface, which forces the sharks to evolve resistance to high concentrations of heavy metals in the water at those depths. They’re also more common, living in the Atlantic Ocean from Iceland and Norway in the north, to Gabon and South Africa in the south. That said, they do grow bigger than dwarf lantern sharks, at up to 45 cm long, over twice as big. They get their name from the velvet black color of their lower bodies, but generally have the same appearance as their cousins. 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.
