ຊີວະສາດ     ຄຳແປສັບ (ຕ.ຢ. epibenthic)

Found on edge of rocky areas, muddy bottom and areas of high sediment load; jetty piles and moorings; often associated with sponges or sea squirts or attached to man-made objects; moves to deeper waters in winter. Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). This species manifested evidence of genetically monogamous character in seahorses (Ref. 59213). Site fidelity is observed during breeding season (Ref. 59213). Length type refers to height (= TL - head length) (Ref. 30915). Minimum depth reported taken from Ref. 128812.

Gestation period 2-3 weeks, depending on water temperature. This species manifested evidence of genetically monogamous character in seahorses (Ref. 59213). Monogamous mating is observed as both obligate and genetic (Ref. 52884). Site fidelity is observed during breeding season (Ref. 59213). Male carries the eggs in a brood pouch (Ref. 205).
