Summary:

A spiderfish with extremely elongated upper pectoral-fin rays, long pelvic fins with thickened lower fin-rays and a a subcaudal notch at the base of the lowere caudal-fin rays. 

These spiderfishes prop high off the seafloor on their long pelvic and caudal fins and face into the current. They extend their long pectoral fins forward to detect their prey of planktonic fishes and invertebrates. Underwater ROV images have shown the trails made when these fishes 'walk' over the seafloor on their pelvic fins and lower tail fin lobe.
