簡短描述 型態特徵 | 形態測量圖

This species is distinguished from its congeners in having the following set of characters: two rows of thorns (strongly hooked and gradually becoming somewhat embedded toward first dorsal fin origin) on mid-dorsum of tail; no thorns at the anterior part of scapular region; thorns on the orbital, nape and scapular regions not encircled by light yellow or white pigment; dorsal surface covered with minute dermal denticles of uniform size and shape, no obvious larger dermal denticles (smooth to touch) (Ref. 86259).

Life cycle and mating behavior 成熟度 | 繁殖 | 產卵場 | | 孕卵數 | 仔魚

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).西北太平洋: 日本外海到越南。

Estimates based on models

Preferred temperature (Ref. 115969): 22.8 - 26.7, mean 25.2 °C (based on 112 cells).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.6250   [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).
營養階層 (Ref. 69278):  3.5   ±0.37 se; based on food items.
回復力 (Ref. 120179):  低的, 最小族群倍增時間4.5 - 14 年 (Fec assumed to be <100).
