The dermal denticles of these animals can be seen in Jose Castro’s The Sharks of North America, and almost look (to me) like cactus spines.
These little guys can be identified by their two dorsal fins that have a) exposed spines and b) a large fringe of horned rays. The second dorsal fin is bigger than the first, as well. Their teeth are different looking, depending which jaw you are looking at. The upper teeth are jagged in multiple areas, with 4 small points and 1 big point. The lower teeth almost resemble tiger shark teeth.
It’s not known if this species of lanternshark has bioluminescence like other lanternsharks, as it has not been seen in the fringefin. However, it is hypothesized that they are bioluminescent.
One of each sex has been found for this species: a 27.5 cm female carrying large, un-fertilized eggs and a 27 cm fully grown male (hypothesized fully grown due to presence of mature claspers). The exact mature size for this species is unknown.
In fact, a lot is not known about this species. So much in fact, that this is all the information I have for you—most of it coming from one source!
