The '''porae''' or '''blue morwong''' |
The '''porae''' or '''blue morwong''' ''Nemadactylus douglasii'' is a [[morwong]] of the genus ''[[Nemadactylus]]'', found around south eastern [[Australia]] and the north eastern coast of the [[North Island]] of [[New Zealand]] at depths of about 10 to 100 metres, on sandy and rocky coasts. Its length is between 40 and 70 . |

The porae is similar in appearance to the [[snapper]] but with a more pointed snout with protruding rubbery lips which it uses to suck up sediment containing small [[invertebrate]] life. The body colour varies from silver-grey to bright silver-blue, even to a copper tinged blue. The middle [[pectoral fin]] ray is greatly elongated to almost 3 times the length of the other rays. These are used to form a tripod when feeding vertically on the bottom. |

The porae or blue morwong, Nemadactylus douglasii, is a morwong of the genus Nemadactylus, found around south eastern Australia and the north eastern coast of the North Island of New Zealand at depths of about 10 to 100 metres, on sandy and rocky coasts. Its length is between 40 and 70 cm.
The porae is similar in appearance to the snapper but with a more pointed snout with protruding rubbery lips which it uses to suck up sediment containing small invertebrate life. The body colour varies from silver-grey to bright silver-blue, even to a copper tinged blue. The middle pectoral fin ray is greatly elongated to almost 3 times the length of the other rays. These are used to form a tripod when feeding vertically on the bottom.
Porae live in the same general area, forming groups, for long periods and, like other morwongs, are long-lived.
They are caught commercially in a small way and are good eating.
