Parupeneus porphyreus, also called whitesaddle goatfish or kūmū in Hawaiian, is endemic to Hawaii.

They have a small white spot, or saddle above the base of the tail and beard-like extrusions called barbels on the lower part of its head, resembling a goats beard.

They shelter in the holes of the reef during the day and forage over sand during the night to find food.

They are located around coral reef fishes in the main and Northwestern Hawaiian Islands.

[5] They live in lagoons and seaward reefs, usually in small groups under ledges or near corals during the day.
