Environment / Climate / Range
Ecology
Marine; bathydemersal; depth range 500 - 1100 m (Ref. 9905). Deep-water, preferred ?
Northwest Pacific: China Sea.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 59.0 cm TL male/unsexed; (Ref. 9905)
Maximum width at least 38 cm. Seldom caught. Utilization for human consumption limited (Ref. 9905). Found in soft, sandy bottoms; by-catch of trawls and usually discarded because of its small size (Ishihara, pers.comm. 07/07).

Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic Level (Ref.
69278): 3.8 ±0.49 se; Based on food items.
Resilience (Ref.
69278): Low, minimum population doubling time 4.5 - 14 years (Assuming fecundity<100).
Vulnerability (Ref.
59153): Moderate to high vulnerability (46 of 100) .
