Northwest Pacific: southern Japan and southwest Korea to the China seas.

Length at first maturity / Size / Weight / Age

Maturity: L_m ?, range 39 - 44 cm
Max length : 53.0 cm TL male/unsexed; (Ref. 6933); 62.0 cm TL (female)

Dwells near shore in sandy mud bottoms (Ref. 11230). Caught throughout the year in coastal waters of southern China. Feeds on small benthic animals. Ovoviviparous (Ref. 50449). Used as `kamaboko' material (Ref. 637).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449). Off southern China, the gestation period is about one year and parturition takes place in June or July.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00324 (0.00159 - 0.00657), b=3.11 (2.93 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.5 ±0.37 se; Based on food items.

Resilience (Ref. 69278): Very Low, minimum population doubling time more than 14 years (Fec=2).

Vulnerability (Ref. 59153): Moderate vulnerability (41 of 100) .

Price category (Ref. 80766): Low.
