Biology

provided by Fishbase
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.

Stigmatopora nigra

provided by wikipedia EN

Stigmatopora nigra, also known as the wide-bodied pipefish is a species of marine fish belonging to the family Syngnathidae.[1] This species can be found in the shallow waters, bays, and estuaries of southern Australia from Shark Bay to Brisbane, Tasmania, and New Zealand.[2][3] They often inhabit seagrass or algae beds in addition to bare sand.[4] Their diet consists of small crustaceans such as copepods and amphipods.[5] Adult brooding males have been measured at 6.5-7 centimeters.[2] Reproduction occurs through ovoviviparity.[6] in which the males brood up to 25 eggs in a pouch below the tail before giving live birth.[2][7] Stigmatopora nigra can live to 150 days old and are able to reproduce throughout the year.[8]

Stigmatopora nigra: Brief Summary

provided by wikipedia EN

Stigmatopora nigra, also known as the wide-bodied pipefish is a species of marine fish belonging to the family Syngnathidae. This species can be found in the shallow waters, bays, and estuaries of southern Australia from Shark Bay to Brisbane, Tasmania, and New Zealand. They often inhabit seagrass or algae beds in addition to bare sand. Their diet consists of small crustaceans such as copepods and amphipods. Adult brooding males have been measured at 6.5-7 centimeters. Reproduction occurs through ovoviviparity. in which the males brood up to 25 eggs in a pouch below the tail before giving live birth.
