Etymology: Eptatretus: Greek, epta = seven + Greek, tretos, -e, -on = with holes (Ref. 45335); poicilus: Named from the Greek poikilos (mottled, varicoloured), in reference to the distinctive mottled colour pattern of its skin (Ref. 115309).
Environment: milieu / climate zone / depth range / distribution range
Marine; bathydemersal; depth range 110 - 842 m (Ref. 115309). Deep-water
Western Pacific: endemic to the Three Kings Islands of New Zealand (Ref. 115309).

Maturity: Lm ?  range ? - ? cm
Max length : 92.1 cm TL male/unsexed; (Ref. 115309)
Morphology | Morphometrics
Diagnosis: 8 pairs of gill pouches and gill openings, strongly mottled with pale brown, dark brown, and white-beige body colour, 3/3 multicusps, and 77–86 total slime pores; distinguished from all other myxinids except Eptatretus gomoni, Eptatretus luzonicus, Eptatretus indrambaryai, Eptatretus okinoseanus, and Eptatretus octatrema by having 8 gill pouches associated with 8 branchial openings; differs from those 5 Indo-Pacific species by having 3-cusp multicusps on the posterior row of teeth (versus 2-cusp multicusps). (Ref. 115309).
From observations of baited videos, this hagfish is much less active feeding on the bait, and is less inclined to produce slime; possible that the colour pattern of this species
offers good camouflage in deep-sea reefs or habitats
composed of sand patches over hard substrate, which
was also abundant in the Three Kings area (Ref. 115309).
