Etymology: Mollisquama: mollis (L.), soft; squama (L.), scale, referring to its soft scales, apparently unique among sharks. (See ETYFish);  mississippiensis: -ensis, Latin suffix denoting place: the “vast” North American Mississippi River Basin, a “biologically and geographically rich region that nurtures Gulf of Mexico [type locality] fauna and unites diverse cultures”. (See ETYFish).

Short description आकृति विज्ञान | मौरफोमैटरिक्स

This species is distinguished from its congeners by the following characters: a putative pit organ centrally placed just posterior to the lower jaw margin; photophores are irregularly distributed along many areas of the body; with a series of 16 ventral-abdominal photophore aggregations; upper teeth no labial-surface ridge (vs. present in M. parini); lower teeth with a weak or absent basal sulcus (vs. deep sulcus in M. parini) (Ref. 121924).

This species was collected with a midwater trawl during a cetacean research project to assess predator/prey trophodynamics for sperm whales (Physeter macrocephalus) of the Gulf of Mexico. Trawl fishing depths were from 5 m of surface to a maximum trawl fishing depth of 580 m over 3,038 m bottom depth; with the sea bottom relatively flat abyssal plain without significant bathymetric features. Environmental sampling conducted within 10 nautical miles of the trawl location with surface/maximum trawling depth environmental data; temperature 21.5°C/7.2°C, oxygen saturation 6.6 mg/l/ 4.0 mg/l, and salinity 36.5 psu/34.9 psu. Other fauna were captured including 44 species identified to lowest taxon (3.3 kg total catch weight, 731 specimens); 29 finfish taxa, 15 invertebrate taxa. Collection locations of M. mississippiensis captured above an abyssal plain 3,038 m depth is influenced by the relatively warm Gulf Stream while M. parini captured above an extensive seamount ridge 330 m depth is influenced by the relatively cold sub-Antarctic Humboldt Current (Ref. 121924).
