生態學
海洋 居於水底的; 深度上下限 20 - 175 m (Ref. 106604). 熱帶
Northwest Pacific; Korea to Vietnam, including Taiwan and southern Japan.
中西太平洋: 從上海 (中國) 到古晉 (砂勞越) 的東南中國海 , 與可能外海的印尼東部。 可能地在印度-太平洋廣泛分佈。
大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm
Max length : 55.0 cm 雄魚/尚未辨別雌雄; (Ref. 9908)
Occur in the sublittoral zone, 70-90 m on sandy mud bottoms (Ref. 11230). 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 measure 6.1 cm long and 3.7 cm wide (Ref. 41249). Utilization details sketchy (Ref. 9908). Very rarely caught by demersal longline fisheries off Java. Utilized for its meat (Ref.58048).
出現在亞潮帶, 在沙泥底上的 70-90 公尺.(參考文獻 11230) 卵生的。 明顯的成對出現。 幼魚可能傾向跟隨大的個體, 例如他們的母親.(參考文獻 205) 卵為長方形鞘囊具有僵硬的觸角沈積在沙灘或泥灘的角落.(參考文獻 205) 卵鞘測量 6.1 公分長與 3.7 公分寬的.(參考文獻 41249) 利用細節不完全.(參考文獻 9908)

Estimates based on models
Preferred temperature (Ref.
123201): 11.5 - 27.2, mean 24.7 °C (based on 98 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00302 (0.00141 - 0.00645), b=3.24 (3.07 - 3.41), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
