Etymology: Zameus: zame, Japanese for shark (at the time, Z. squamulosus was known only from Japan) (See ETYFish); squamulosus: Latin for covered or beset with small scales, “so minute as to give a velvety appearance to the skin” (See ETYFish).

ການຖ່າຍທອດທາງກຳມະພັນຈາກພໍ່ແມ່ຫາລູກ: 0. Black in color, small dorsal fin spines, moderately long snout, small lanceolate teeth without cusplets in upper jaw and large high, knife-cusped cutting teeth in lower jaw, mouth moderately wide and nearly transverse, caudal fin with strong subterminal notch and short lower lobe (Ref. 247).
Demersal or pelagic near continental slopes and seamounts in depths of 550-2,000 m (Ref. 6871, 58302). Also found from the surface to 580 m over deep water (Ref. 26346). Ovoviviparous (Ref. 205). Used dried and salted for human consumption and for fishmeal (Ref. 6871). Caught rarely by longline fisheries operating in deepwater; also caught, but rarely landed, by pelagic tuna longline fisheries (Ref.58048).

Distinct pairing with embrace (Ref. 205). Presumambly viviparous, with yolk-sac dependancy (Ref.58048).
