Morphology | Morphometrics
soft rays: 4. Body slender and snout elongate, continuous superior and inferior trunk and tail ridges, a dorsal fin which originates on trunk rings 5-9, and an extremely slender tail without a caudal fin. The trunk is broad in females and the brood pouch in males is on the underside of the tail immediately behind the anal fin. No caudal fin. Body rings: 16-19 + 67-79.
Occur in bays, estuaries and shallow coastal waters. Occurs among seagrass and algae (Ref. 31838). Occasionally found in floating seaweed (Ref. 31838). Ovoviviparous (Ref. 205). The male carries the eggs in a brood pouch which is found under the tail (Ref. 205). Males may be brooding at 6.5-7 cm TL.
Up to 41 eggs are incubated by the male in a brood pouch formed from laterally expanded flaps of skin on the underside of the tail. Newly emerged larvae may remain in the pouch (Ref. 31838).
