Western Pacific: Japan, Sea of Okhotsk and the East China Sea.
Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 14.5-16.0 cm long and 7.0-7.5 cm wide (Ref. 41249, 41253, 41298).

Estimates of some properties based on empirical models
Phylogenetic diversity index (Ref. 82805): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00331 (-0.17356 - 0.18017), b=3.21 (3.11 - 3.31), based on LWR estimates for this family-BS (Ref. 93245).
Trophic Level (Ref. 69278): 3.7 ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref. 59153): High to very high vulnerability (69 of 100) .
