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 10.6-13.2 cm long and 7.6-8.6 cm wide (Ref. 41298, 41253).
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) 卵鞘是 10.6-13.2 公分長與 7.6-8.6 公分寬的.(參考文獻 41298,41253)
